Patent ID: 8177790

Claim:
A medical retrieving device for capturing and extraction of a spiral helix from a blood vessel with said device having a guide wire ( 3 ), having a proximal end, a distal region, and a free end, and which bends back on itself in its distal region where it consists of a loop structure ( 13 ) so that an anchoring part ( 2 ) in the form of a hook is created, with the free end ( 7 ) of the guide wire ( 3 ) pointing towards the proximal end of the guide wire ( 3 ) so that it can be hooked on the spiral helix ( 8 ) to be extracted, wherein the device is characterized in that the free end ( 7 ) of guide wire ( 3 ) has a corkscrew-like configuration pointing to the proximal end of the guide wire ( 3 ), and further characterized in that at least the distal region of the loop structure ( 13 ) is arranged at an angle relative to a run of the guide wire ( 3 ) which is conducive to the capturing process and further characterized in that the loop structure ( 13 ) forms a loop ( 4 ) having a plane formed by the loop, said plane being inclined relative to the run of the guide wire ( 3 ), for facilitating steering of the medical retrieving device through vascular bends.
