Abstract:
1. A system for delivering and retrieving multiple embolic filters which employs a single delivery and retrieval sheath, the system comprising: a first filter wire segment having a distal region and a proximal region; a first embolic filter deployable from the first filter wire segment and operatively coupled to the distal region thereof; a second filter wire segment having a distal region and a proximal region; a second embolic filter deployable from the second filter wire segment and operatively coupled to the distal region thereof; a delivery and retrieval sheath having a distal end, a proximal end, and at least one lumen therebetween configured and adapted to slidably contain a filter wire; a first distal sheath segment associated with the distal end of the delivery and retrieval sheath, said first distal sheath segment having a lumen configured and adapted to contain the first embolic filter in a collapsed state; and a second distal sheath segment associated with the distal end of the delivery and retrieval sheath, said second distal sheath segment having a lumen configured and adapted to contain the second embolic filter in a collapsed state, wherein the first filter wire segment passes at least in part through the lumen of the first distal sheath segment, further wherein the second filter wire segment passes at least in part through the lumen of the second distal sheath segment, and wherein the first and second distal sheath segments are configured and adapted to deploy the respective first and second filters at locations which are longitudinally displaced from each other.
