Abstract
A device for retrieving an intravascular device from a body lumen is disclosed. A retrieval device in accordance with an exemplary embodiment of the present invention includes a braided member coupled to an elongated shaft member. The braided member may include a number of filaments defining a radially expandable inner lumen configured to receive and encapsulate the intravascular device therein. An elastomeric jacket disposed about at least a portion of the braided member may encase the filaments.
