Abstract
A vena cava filter catheter includes a catheter having a lumen disposed therethrough and at least one strand of biocompatible wire. The at least one strand has a first state in which the at least one strand has an elongate geometry suitable for traversing the lumen of the catheter and a second state in which the at least one strand assumes a pre-set geometry in which the at least one strand assumes a tortuous configuration adapted to occupy a space approximating a luminal diameter of an inferior vena cava.
Claims10
A method for implementing a vena cava filter catheter, wherein the vena cava filter catheter includes a catheter having at least one lumen disposed therethrough, the method comprising the steps of:
- a. advancing at least one strand of a biocompatible wire in a first state having an elongate geometry through the at least one lumen of the catheter;
- b. pushing the at least one strand out of the catheter through an opening therein such that the at least one strand deploys to a second state having a tortuous configuration adapted to occupy a space approximating a luminal diameter of an inferior vena cava.
