Definitions
- This invention relates to a device for controlling post-partum hemorrhage, and more particularly, to a tamponade device for controlling uterine and vaginal postpartum hemorrhage.
- Postpartum hemorrhage is most commonly caused by uterine atony whereby the uterus fails to contract normally after the delivery of a baby. This condition occurs in about 5 percent of deliveries. Hemorrhage continues to be one of the major causes of maternal deaths generally, with obstetrical hemorrhage being the third leading cause of maternal death by hemorrhage in the United States. Worldwide, maternal hemorrhage qualifies as the leading cause of maternal death.
- Techniques for managing obstetrical hemorrhage may be medical, mechanical, or surgical. Hysterectomy, while an effective surgical procedure for treating this condition, bears severe consequences, in particular for young women who have not completed childbearing.
- U.S. Pat. No. 4,619,261 issued on Jun. 17, 1980 to Guerriero discloses a hydrostatic pressure application device for controlling bleeding from an internal wound.
- the device of Guerriero comprises a balloon captured within a net.
- the net is secured to an area surrounding a wound with surgical sutures, so that hydraulic pressure applied to the balloon expands the balloon and causes pressure to be applied at the wound. Pressure so applied at the wound causes a cessation in bleeding.
- applying and removing the device of Guerriero requires an operative (surgical) procedure.
- U.S. Pat. No. 4,207,891 issued on Jun. 17, 1980 to Bolduc discloses a fluid dispensing instrument having a dispenser that operates to place a drug material into a uterine cavity, and an expandable balloon that operates to move the drug material from the uterine cavity into both canals of the Fallopian tubes.
- the dispensing instrument of Bolduc is not configured and operated in a manner directed to the control of post-partum hemorrhage and bleeding.
- U.S. patent application Ser. No. US2001/0007945 published on Jul. 12, 2001 to Piraka discloses a uterine balloon for controlling hemorrhaging in a patient after childbirth.
- the balloon of Piraka is filled with a physiologic solution by means of a catheter inserted through a valve in the balloon.
- a fill system, a control system, and a pressure relief valve are each employed for maintaining a constant solution pressure in the balloon.
- no means are disclosed for determining whether bleeding has been effectively stopped, in order to adapt balloon pressure accordingly.
- a novel device and method are disclosed for controlling uterine and vaginal postpartum hemorrhage.
- the present invention comprises a tamponade device having an inflatable balloon whose shape, when inflated, takes on the shape of the site to be controlled (for example, the shape of a uterine wall).
- the device also comprises an internal drain tube coaxially and sealably positioned with respect to the balloon, and having a port at an inserted end for draining blood and other fluids from the uterine cavity.
- An insufflation tube feeds a distending medium (such as air or a physiologic fluid) through a supply tube to inflate the balloon.
- the supply tube co-axially encircles the drain tube to define a thin passageway between an inner surface of the supply tube and an outer surface of the drain tube. Perforations in the supply tube allow the medium to pass from this passageway in order to distend the balloon.
- the balloon exerts a uniform distribution of compressive pressure, which in turn controls bleeding sites.
- This control of bleeding gives the uterus time to respond normally as bleeding stops, and conserves blood while preparing the patient for surgery as necessary.
- This device may also be utilized in the vagina to control bleeding associated with submucosal tears ( tears under the mucosal vaginal lining), and with any continuous bleeding resulting in the subsequent development of hematomas. Accordingly, significant blood loss, pain, and the possibility of an operative procedure may be prevented.
- an outer surface of the balloon is coated or impregnated with a hemostatic material for contact with the uterine wall or vaginal lining to provide additional control of bleeding.
- An advantage provided by the present invention is that its insertion, inflation, and removal require no surgical procedures, and very little time.
- the device is thus uniquely and admirably suitable for use in uterine hemorrhaging emergencies.
- Other presently known devices which use expandable material to stop abdominal bleeding during or after surgery are considerably more complicated in construction and much more difficult to use, often requiring surgical application and removal.

Abstract
Description
- The present application claims priority under 35 U.S.C. § 119(e) from U.S. Ser. No. 60/XXX,XXX, filed on Jul. 13, 2001. U.S. Ser. No. 60/XXX,XXX was filed by at an inventor common to the present application, and is hereby incorporated by reference.
- This invention relates to a device for controlling post-partum hemorrhage, and more particularly, to a tamponade device for controlling uterine and vaginal postpartum hemorrhage.
- Postpartum hemorrhage is most commonly caused by uterine atony whereby the uterus fails to contract normally after the delivery of a baby. This condition occurs in about 5 percent of deliveries. Hemorrhage continues to be one of the major causes of maternal deaths generally, with obstetrical hemorrhage being the third leading cause of maternal death by hemorrhage in the United States. Worldwide, maternal hemorrhage qualifies as the leading cause of maternal death.
- Techniques for managing obstetrical hemorrhage may be medical, mechanical, or surgical. Hysterectomy, while an effective surgical procedure for treating this condition, bears severe consequences, in particular for young women who have not completed childbearing.
- One of the mechanical procedures often used for managing obstetrical hemorrhage involves packing the uterus with heavy gauze. This procedure remains controversial because of a high failure rate, and is considered a waste of time by some medical practitioners. The high failure rate is attributable to the inherent difficulty in packing the uterus properly so that there is an even distribution of pressure along the entire inner surface of the organ.
- Accordingly, a more effective procedure is needed to address post-partum hemorrhage and bleeding. Ideally, the procedure should present minimal long-term health consequences to the patient, be quickly and easily accomplished, be easily learned and require no specialized instrumentation.
- U.S. Pat. No. 4,619,261 issued on Jun. 17, 1980 to Guerriero, discloses a hydrostatic pressure application device for controlling bleeding from an internal wound. The device of Guerriero comprises a balloon captured within a net. The net is secured to an area surrounding a wound with surgical sutures, so that hydraulic pressure applied to the balloon expands the balloon and causes pressure to be applied at the wound. Pressure so applied at the wound causes a cessation in bleeding. Disadvantageously, however, because the device is sutured to an area surrounding the wound, applying and removing the device of Guerriero requires an operative (surgical) procedure.
- U.S. Pat. No. 4,207,891 issued on Jun. 17, 1980 to Bolduc, discloses a fluid dispensing instrument having a dispenser that operates to place a drug material into a uterine cavity, and an expandable balloon that operates to move the drug material from the uterine cavity into both canals of the Fallopian tubes. However, the dispensing instrument of Bolduc is not configured and operated in a manner directed to the control of post-partum hemorrhage and bleeding.
- U.S. patent application Ser. No. US2001/0007945 published on Jul. 12, 2001 to Piraka discloses a uterine balloon for controlling hemorrhaging in a patient after childbirth. The balloon of Piraka is filled with a physiologic solution by means of a catheter inserted through a valve in the balloon. A fill system, a control system, and a pressure relief valve are each employed for maintaining a constant solution pressure in the balloon. However, no means are disclosed for determining whether bleeding has been effectively stopped, in order to adapt balloon pressure accordingly.
- None of the above-described devices provide the full advantage of the novel device and method described herein.
- A novel device and method are disclosed for controlling uterine and vaginal postpartum hemorrhage.
- The present invention comprises a tamponade device having an inflatable balloon whose shape, when inflated, takes on the shape of the site to be controlled (for example, the shape of a uterine wall). The device also comprises an internal drain tube coaxially and sealably positioned with respect to the balloon, and having a port at an inserted end for draining blood and other fluids from the uterine cavity. An insufflation tube feeds a distending medium (such as air or a physiologic fluid) through a supply tube to inflate the balloon. The supply tube co-axially encircles the drain tube to define a thin passageway between an inner surface of the supply tube and an outer surface of the drain tube. Perforations in the supply tube allow the medium to pass from this passageway in order to distend the balloon.
- With sufficient inflation pressure, the balloon exerts a uniform distribution of compressive pressure, which in turn controls bleeding sites. This control of bleeding gives the uterus time to respond normally as bleeding stops, and conserves blood while preparing the patient for surgery as necessary. This device may also be utilized in the vagina to control bleeding associated with submucosal tears ( tears under the mucosal vaginal lining), and with any continuous bleeding resulting in the subsequent development of hematomas. Accordingly, significant blood loss, pain, and the possibility of an operative procedure may be prevented. In a preferred embodiment of the present invention, an outer surface of the balloon is coated or impregnated with a hemostatic material for contact with the uterine wall or vaginal lining to provide additional control of bleeding.
- An advantage provided by the present invention is that its insertion, inflation, and removal require no surgical procedures, and very little time. The device is thus uniquely and admirably suitable for use in uterine hemorrhaging emergencies. Other presently known devices which use expandable material to stop abdominal bleeding during or after surgery are considerably more complicated in construction and much more difficult to use, often requiring surgical application and removal.
- A more complete understanding of the invention may be obtained by reading the following description of specific illustrative embodiments of the invention in conjunction with the appended drawing in which:
- FIG. 1 illustrates a cross-sectional view of a hemorrhage control device according to the present invention; and
- FIG. 2 illustrates a mechanism for supplying fluid to fill a balloon of the hemorrhage control device.
- The following detailed description includes a description of the best mode or modes of the invention presently contemplated. Such description is not intended to be understood in a limiting sense, but to be an example of the invention presented solely for illustration thereof, and by reference to which in connection with the following description and the accompanying drawing one skilled in the art may be advised of the advantages and construction of the invention.
- Referring to the FIG. 1,
hemorrhage control device 100 comprises aninner drain tube 10 and anouter sheathing 20.Outer sheathing 20 coaxially surroundsinner drain tube 10 over lengths defined byinsertable portion 22 andexternal portion 23. Overexternal portion 23,outer sheathing 20 is sealably attached toinner drain tube 10. Overinsertable portion 22,outer sheathing 20 comprises aballoon 24 that may be distended with a medium (gas or fluid) viainsufflation tube 25 andsupply tube 25 a to occupy an expanded shape. At one end,balloon 24 meetsexternal portion 23 of sheathing 20 atseal 27. Near an end ofinsertable portion 22, seal 21 fixedly and sealablyjoins another end ofballoon 24 toinner drain tube 10. -
Seals balloon 24, and for restraininginner drain tube 10 toballoon 24.Insufflation tube 25 sealably surroundsinner drain tube 10 at anend 25 b that joins to supplytube 25 a.Supply tube 25 a co-axially encirclesdrain tube 10 to definepassageway 26 a betweensupply tube 25 a anddrain tube 10. Atend 25 b,passageway 26 ofinsufflation tube 25 couples topassageway 26 a ofco-axial supply tube 25 a for delivering the distending medium to the interior volume ofballoon 24 via a plurality ofperforations 28 distributed overregion 29 ofco-axial supply tube 25 a.Supply tube 25 a andpassageway 26 a sealably terminate near a terminatingend 25 c ofinner drain tube 10. - As shown in FIG. 1,
insufflation tube 25 preferably mates withinflation control valve 30 for maintainingballoon 24 in an inflated state, and for controllably deflatingballoon 24 when it is required that pressure supplied to the uterine cavity be reduced or altogether removed.Valve 30 may comprise one of a variety of conventional devices including, for example, ball valves and needle valves.Valve 30 may alternatively comprise a connecting area (for example, using a glass adapter) for connecting a fluid tube toinsufflation tube 25. -
Balloon 24 is made of an expandable material, such as urethane, natural rubber, silicone, synthetic rubber or vinyl, and may preferably be inflated hold up to 4000 cubic centimeters (cc) of air volume.Balloon 24 is also preferably heart-shaped when inflated so that it will evenly conform, for example, to the interior surface of the uterine wall. Conformance of the exterior shape ofballoon 24 with the interior shape of the uterine wall enablesballoon 24 to fit evenly and tightly against this surface, thereby providing pressure against all associated bleeding sites. - An external surface of
balloon 24 may preferably be coated, impregnated or otherwise covered with a hemostatic material in order that this hemostatic material may come into direct contact with the uterine wall or vaginal lining to further assist in controlling bleeding. Oxidized cellulose and hemotene are materials suitably used for this purpose. -
Inner drain tube 10,outer sheathing 20 andinsufflation tubes 25, andsupply tube 25 a may also be made from a flexible material such as neoprene, natural rubber, silicone, synthetic rubber or vinyl.Inner drain tube 10 however must be sufficiently rigid to maintain its inner diameter whenballoon 24 is inflated, and therefore may either be made from a more rigid material thanballoon 24 or have a thicker cross-section thanballoon 24. - As illustrated by FIG. 1,
inner drain tube 10 has adrainage port 11 at its distal end for receiving blood and other fluids to be drained from the uterine cavity. Without adequate drainage, bleeding may continue unobserved in spite of the pressure applied byballoon 24, and may possibly lead to severe bleeding diathasis. At an end ofexternal portion 23,inner drain tube 10 may optionally include expandedportion 13 for couplinginner drain tube 10 to another vessel having, for example, a passageway of like inner diameter toinner drain tube 10.Inner drain tube 10 may also be used, for example, to irrigate the uterus as necessary by introducing irrigation fluids at expandedportion 13. -
Hemorrhage control device 100 of FIG. 1 may be simply operated by inserting thedevice 100 to a desired position in the uterine cavity and inflatingballoon 24 to a desired pressure and volume. Optimum pressure is detected, for example, when there is no further fluid drainage. After an appropriate length of time, pressure can be lowered and observations made to determine whether or not bleeding has been controlled, and to determine whether the uterus is showing signs of contracting normally. If bleeding begins again or the uterus remains soft and boggy, the balloon may be re-inflated. - When the device is used to stop bleeding in the vagina due to submucosal tears, it will require a much smaller volume of gas or fluid for
balloon 24 to accommodate itself to the shape of the vagina. Optimally formed balloon shapes and sizes in either uterine or vaginal applications will vary with patient anatomy. Accordingly, a variety of balloon shapes and sizes may be employed in the present invention, each of which is fully contemplated within the scope of the present invention. - A variety of gases (for example, air) and fluids may be used to inflate
balloon 24 of FIG. 1. In a preferred embodiment of the present invention, a fluid comprising a normal saline solution is used to inflate the balloon. Fluid media have an advantage over gaseous media in decreasing the risk of generating embolisms. - FIG. 2 illustrates an
apparatus 200 for supplying a fluid medium to thehemorrhage control device 100. In theapparatus 200, intravenous (IV) bag 40 contains asaline solution 46. Bag 40 may be hung approximately three to four feet above a position ofhemorrhage control device 100 in order to provide sufficient supply pressure for inflatingballoon 24 ofhemorrhage control device 100 to curtail bleeding.Adapter 41 may be used to coupletube 44 tocoupling tube 42, and thereby tovalve 30 ofhemorrhage control device 100.Hemostat 45 may be used to clamptube 44 for controlling the flow ofsaline solution 46 into the balloon ofhemorrhage control device 100. When it is desired to reduce pressure or volume of the balloon,tube 44 may be disconnected atadapter 41, andcoupling tube 42 positioned so that fluid is able to drain fromdevice 100 by gravity flow. - While the present invention has been described at some length and with some particularity with respect to the several described embodiments, it is not intended that it should be limited to any such particulars or embodiments or any particular embodiment, but it is to be construed with references to the appended claims so as to provide the broadest possible interpretation of such claims in view of the prior art and, therefore, to effectively encompass the intended scope of the invention.
