Abstract

Devices, systems and methods are provided for performing intra-lumenal medical procedures in a desired area of the body. Retrieval devices and methods of performing medical procedures to remove foreign objects to re-establish the intravascular flow of blood are provided.

Claims

1. A medical device for retrieving objects in a patient comprising:

an elongate tubular sheath having distal and proximal ends and a lumen extending therethrough,

an elongate flexible member having distal and proximal ends defining a longitudinal axis and being positioned within the lumen of said sheath,

a capture member coupled to the distal end of said flexible member, said capture member having first and second resilient capture arms biased outwardly from said longitudinal axis, said capture arms including a plurality of engagement elements extending from each capture arm in a direction generally perpendicular to said longitudinal axis, said capture arms being operable between a constrained configuration wherein said engagement elements of said first capture arm intermesh with said engagement elements of said second capture arm and an unconstrained configuration wherein said engagement elements of said capture arms are non-intermeshing.

2. The medical device of claim 1 wherein said capture member comprises nitinol.

3. The medical device of claim 1 wherein said capture member includes a radiopaque material.
