1. A filter exchange system, comprising:
- a filter assembly including a filter member coupled to an elongated wire;
an exchange sheath having a proximal end and a distal end, the exchange sheath defining a guidewire sheath and a filter sheath;
the guidewire sheath having a proximal end, a distal end, a length, and a guidewire lumen adapted to receive a guidewire therethrough, said guidewire lumen including an open discontinuous portion exposing at least a portion of the length of the guidewire sheath; and
the filter sheath having a proximal end, a distal end, and a filter lumen adapted to receive at least a portion of the filter member therein.

Abstract
Vascular embolic filtering systems, as well as methods for using the same, are provided. In general, the subject invention includes a system comprised of an embolic filter assembly and a multiple lumen delivery and retrieval sheath, where the embolic filter assembly includes a guide wire with an embolic filter operatively coupled to the distal end of the guide wire for capturing emboli created during interventional procedures within a target vessel. Features of the subject invention provide for the rapid exchange and deployment of embolic filters in a patient'"'"'s vasculature.
