Claim:
1. A medical device for removing an obstruction from a body passage, the medical device comprising: at least one leading wire having a first end and a second end; a capturing portion having a surface extending between an open proximal end and a permeable distal end; where the at least one leading wire extends through an interior of the capturing portion and diverges to form the permeable distal end, the at least one leading wire extends back in a proximal direction to form the capturing portion; and where the surface of the capturing portion comprises a translating surface formed of the at least one leading wire and a capturing surface, each being configured so that the at least one leading wire causes a translating surface axial strength to be greater than a capturing surface axial strength, wherein application of a tensile force on the at least one leading wire causes axial compression of the capturing surface before causing axial compression and deformation of the translating surface as the capturing portion engages the obstruction.
