Abstract:
1. 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. expanding a collapsible filter within an inferior vena cava and capturing embolic material within the collapsible filter; b. 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; c. pushing the at least one strand out of the catheter through an opening in the catheter and through the expanded collapsible filter including any captured embolic material within the expanded collapsible filter such that the at least one strand deploys distal the expanded collapsible filter and to a second state having a convoluted and tortuous configuration said configuration adapted to create multiple regions for capture of embolic material dislodged distally from the collapsible filter and occupy a space approximating a luminal diameter of an inferior vena cava.
