    • FIELD OF THE INVENTION
  • The present invention relates, in general, to deflectable medical device shafts, and, in particular, to deflectable catheter shafts.
    • BACKGROUND OF THE INVENTION
  • In order to facilitate the advancement of catheters through body lumens such as an artery, deflectable catheters have been developed. The simultaneous application of torque at the proximal portion of the catheter and the ability to selectively deflect the distal tip of the catheter in a desired direction permits the physician to adjust the direction of advancement of the distal portion of the catheter, as well as to position the distal portion of the catheter during, for example, delivery of an occlusive implant.
  • A physician may manipulate the proximal portion of the catheter to guide the catheter through the vasculature. The deflection of the distal tip is typically provided by one or more steering wires that are attached at the distal portion of the catheter and extend to a control handle that controls the application of tension in the steering wires. In order to maneuver around turns and bends in the vasculature, the physician observes the catheter fluoroscopically, and selectively deflects the tip and rotates the proximal portion of the catheter shaft.
  • It is critically important to have sufficient flexibility in the distal portion of the catheter shaft so that when the catheter is advanced through a blood vessel, the catheter may follow the inherent curvature of the vessel without puncturing the vessel wall. However, it is also important to maintain stiffness in the proximal portion of the catheter shaft to allow the distal portion of the catheter to be manipulated by the physician. Therefore, there exists a need for a catheter shaft having a flexible, atraumatic distal portion while maintaining a sufficiently stiff proximal portion.
    • SUMMARY OF THE INVENTION
  • An aspect of the invention involves a medical device shaft for connection with a handle and for insertion within a body. The medical device shaft includes an elongated, deflectable shaft having a proximal shaft portion, an intermediate shaft portion, and a distal shaft portion. The elongated, deflectable shaft includes a transition in stiffness from the proximal shaft portion to the distal shaft portion. In a preferred implementation, the shaft includes a plurality of slits that extend perpendicular to a longitudinal axis of the shaft. Varying at least one of the number of slits, the location of slits, the frequency of slits, the orientation of the slits, the size of the slits, and the depth of the slits varies the transition of stiffness.
  • Other features and advantages of the invention will be evident from reading the following detailed description, which is intended to illustrate, but not limit, the invention.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to FIG. 1, a catheter 10 including a torqueable and deflectable shaft or body 20 constructed in accordance with an embodiment of the present invention will now be described. The catheter 10 will first be generally described before describing the torqueable and deflectable shaft or body 20. The catheter shaft 20 will be described as being used within the vascular system of a patient; however, the catheter shaft 20 may be used within other lumens, passages, ducts, tracts, openings, etc. in the body other than blood vessels. Further, the shaft 20 may be a torqueable and deflectable shaft or body of a medical device other than a catheter.
  • The catheter body 20 includes an operative distal tip portion 50. The catheter 10 further includes a catheter handle 60 with a steering knob 70 to control the distal tip portion 50 of the catheter body 20 when guiding the distal tip portion 50 through the vascular system of the body. The steering knob 70 is attached to steering wires that extend through an interior lumen of the catheter body 20. The steering wires terminate and are anchored near the distal tip portion 50 so that rotation of the steering knob 70 causes deflection and bending of the shaft 20 near the distal portion 50 as shown.
  • The operative distal tip portion 50 may take any known construction in the art. For example, but not by way of limitation, the operative distal tip portion 50 may include an implantable and detachable occlusion device, a probe assembly, an expandable basket assembly, an expandable balloon or body, one or more electrodes for sensing, pacing, and/or ablating, one or more markers for identifying the distal tip portion, an imaging device, and any combination of the above. In the embodiment of the operative distal tip portion shown, two ring electrodes 100, 110 are disposed along the length of the distal tip portion 50 to provide radio frequency energy for ablation and/or sensing of electrical activity in body tissue. In addition, a radiopaque marker band 120 is secured to the distal tip portion 50 to facilitate visualization of the distal tip portion 50 inside the body using fluoroscopy.
  • FIGS. 2A and 2B relate to illustrate the body or shaft 20 of FIG. 1 in more detail. The shaft 20 includes a proximal shaft portion 140, an intermediate shaft portion 145, and a distal shaft portion 150. The shaft increases in flexibility from the proximal shaft portion 140 to the distal shaft portion 150. The distal shaft portion 150 includes the distal tip portion 50 and is comprised of a ribbon braid 170 of counter-wound double Nitinol wires embedded in a layer of hydrophobic polymer 180 to prevent the braiding 170 from being exposed. The polymer layer 180 may be covered with a hydrophilic coating. This construction allows the distal shaft portion 150 to be flexible or bendable in a lateral direction to facilitate steering of the shaft 20, but has enough torsional strength to allow torque to be efficiently transmitted by the user from the handle to the distal shaft portion 150 without give in the shaft 150.
  • The ribbon braid 170 is preferably made from Nitinol in order to create a shaft that minimizes kinking, transmits a high amount of torque, and retains its shape after being bent. Importantly, a Nitinol braid 170 allows increased flexibility in the distal tip portion 50, but keeps the interior lumen from collapsing by inhibiting kinking Additionally, because Nitinol is a memory metal, a user may easily maintain the distal tip portion 50 in a desired shaped throughout a surgical procedure. In other embodiments, the braid 170 may be made of different materials such as metal alloys (e.g., stainless steel, carbon fiber).
  • The proximal shaft portion 140 and intermediate shaft portion 145 are preferably made of a substantially hollow Nitinol tubing 182 coated with the hydrophobic polymer layer 180. The polymer layer 180 may be covered with a hydrophilic coating. The Nitinol tubing 182 is designed to transmit torque to provide a substantially one-to-one correspondence between rotation of the proximal shaft portion 140 and distal shaft portion 150. The Nitinol tube 182 provides the shaft 150 with sufficient flexibility for advancing the shaft 150 through a tortuous lumen path and sufficient torsional strength to efficiently transmit torque from the handle 60 to the distal shaft 150. The tube 182 is also preferably made of Nitinol to minimize kinking and because Nitinol is a memory metal that retains its shape after being bent. In other embodiments, the tube 182 may be a made of a material other than Nitinol such as, but not by way of limitation, carbon fiber or a metal alloy such as stainless steel.
  • The shaft 20 increases in flexibility from a proximal junction 184, where the shaft 20 meets a luer attachment 185, to a distal junction 186, where the Nitinol tube 182 attaches to the Nitinol braid 170 of the distal shaft portion 150. The increase in flexibility is created by making a plurality of slits or cuts 188 along the hollow tube 182. These slits 188 extend perpendicular to a longitudinal axis of the shaft 20. An increase in flexibility in the shaft 20 from the proximal junction 184 to the distal junction 186 may be achieved by increasing the depth of the slits 188 as one progresses from the proximal junction 184 to the distal junction 186 and/or by increasing the number of slits 188 per unit length of tube 182 as one progresses from the proximal junction 184 to the distal junction 186. As best seen in FIG. 2A, the number of slits 188 per length of tube increases gradually from the proximal shaft portion 140 to the distal junction 186. Additionally, the slits 188 become increasingly deeper toward the distal junction 186. As a result, a transition in stiffness is formed, whereby the shaft 20 becomes progressively more flexible from proximal shaft portion 140 to distal shaft portion 150. The number of slits 188, location of slits 188, frequency of slits 188, orientation of the slits 188, size of the slits 188, and/or depth of the slits 188 may be varied to vary the transition of stiffness according to the desired application of the shaft 20.
  • While preferred embodiments and methods have been shown and described, it will be apparent to one of ordinary skill in the art that numerous alterations may be made without departing from the spirit or scope of the invention. Therefore, the invention is not limited except in accordance with the following claims.
