Definitions
- means may be provided to shroud at least some of the drainage means while the catheter is being thrust into the region.
- the catheter comprises a pair of flexible fins which surround a catheter tube on each side of a passage through its wall.
- the passage is an inlet means to the lumen of the tube.
- These fins are joined to each other at a peripheral junction so as to form a chamber in communication with the passage.
- a plurality of perforations through at least one of the fins augments the inlet means in the sense of providing an increased total flow channel to the lumen of the tube without requiring enlargement of the passage, which could risk the passage of particulate matter of excessive size.
- This invention relates to a catheter for the drainage of fluids from within the human body.
- a conventional catheter is a tube with an axially extending lumen which, near one end thereof has a passage in the nature of an inlet port extending between the lumen and the outer wall. After the catheter is thrust in to a region holding unwanted fluids, the fluid may enter the inlet port and flow through the lumen to be disposed of either outside the body or in some region within the body where a further disposal process takes place.
- a well-known application for such a catheter is in the alleviation of the symptoms of hydrocephalus. ln such cases, a catheter is thrust into the ventricles of the brain in order to drain unwanted fluid therefrom, and is then led through the jugular vein into the heart so that the fluid from the ventricles enters the blood stream and is disposed of in the process of purification of the blood.
- a problem encountered with conventional catheters is that the debris created by its insertion may clog the inlet port during the insertion process. Furthermore, in applications such as in drainage of the brain, the matter of the brain is thrust aside upon insertion and when the brain is decompressed by drainage of the fluid, it tends to bear against the wall of the catheter, thereby potentially clogging the inlet port. Also, the fluids to be drained are frequently burdened with particulate matter which can clog up single openings as so often are provided in conventional catheters.
- a catheter according to this invention comprises a tube having an internal longitudinal lumen with an inlet port or passage passing through its wall to the lumen.
- a pair of circumferential flexible fins are attached to the outer wall of the tube on each side of the opening and are connected to each others peripheries so as to form a chamber between them in fluid communication with the inlet port.
- a plurality of perforations is provided in at least one of the fins and may be provided in both. Advantages are obtained when only that one of the fins of each pair which is the farther from the tip is perforated.
- FIG. 1 is a perspective drawing showing the presently preferred embodiment of this invention together with a tool for its insertion;
- F l6. 2 is a perspective drawing partly in cutaway cross section showing the catheter of the invention in the process of being inserted into the brain;
- FIG. 3 shows the device of F I68. 1 and 2 in the brain
- FIG. 4 is a cross section taken at 4-4 ofFIG. l.
- FIG. 5 is a axial cross section taken at line 5-5 of FIG. 2.
- F lG. 1 The presently preferred embodiment of the invention is shown in F lG. 1 wherein a catheter is shown which includes an elongated tube 11 having a central lumen 12 comprising a cylindrical interior bore ending at a closed tip 13.
- Drainage means 14 comprising a laterally extending hole extending between the lumen 12 and outer wall 15 of the tube is provided to permit fluid from outside the tube to be drained to the internal lumen and thus to be removed from the body.
- drainage means hereinafter frequently referred to as drain ports
- drain ports have been all the openings which exist, and these have been subject to clogging by particulate matter contained in the fluid to be drained and also by contact with the surrounding tissue which has been pushed aside upon insertion of the catheter itself.
- a pair of circumferential fins 20, 21 are bonded to, or otherwise formed integrally with, outer wall 15. These include annular disclike surfaces which are joined at their outer peripheral edges 22, 23 respectively by cementing or fusion so as to form inside chambers 24, which chambers are in fluid communication with respective ones of ports 14.
- each pair of fins is provided with perforations 25 to provide for admission of fluids from the surrounding region into the chamber.
- perforations 25 are provided only in the fins which are on the opposite side of the tip from the other member of the respective pair of fins.
- this device provides a means optionally for shrouding the perforations of the catheter upon insertion into the brain or the region to be drained, and thereafter when the means for insertion is removed, to provide an augmented inlet means such that a particle of material might clog up one perforation, but not the inlet passage, so that the device is not disabled.
- the perforations in the fins would preferably be smaller than the diameter of port 14.
- the entire structure is preferably made of medical grade silicone rubber, and joined as appropriate by a similar type of cement. I
