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 element coupled to the distal end of said flexible member, said capture element having a pair of resilient capture arms biased outwardly from said longitudinal axis and an engagement member positioned between said capture arms, said engagement member having a plurality of engagement elements spaced apart and extending outwardly from said engagement member.

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

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

4. The medical device of claim 1 wherein said engagement elements extend in a generally proximal direction.

5. The medical device of claim 4 wherein said engagement elements are oriented substantially parallel to the plane defined by said capture arms.

6. 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 element coupled to the distal end of said flexible member, said capture element having a pair of resilient capture arms biased outwardly from said longitudinal axis and an engagement member positioned between said capture arms, said engagement member having a plurality of engagement elements spaced apart along the length of said engagement member.

7. The medical device of claim 6 wherein said capture element comprises nitinol.

8. The medical device of claim 6 wherein said capture element includes a radiopaque material.

9. The medical device of claim 6 wherein said engagement elements extend in a generally proximal direction.

10. The medical device of claim wherein said engagement elements are oriented substantially parallel to the plane defined by said capture arms.
