Vena cava filter catheter and method

摘要

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: advancing at least one strand of a biocompatible wire in a first state 5 having an elongate geometry through the at least one lumen of the catheter; 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.
