Patent ID: 8043302

Claim:
An implant retrieval assembly for retrieval of an implant in a body vessel, the assembly comprising: an implant retrieval device comprising; an outer sheath having a proximal portion and a distal portion; an inner catheter movably disposed through the outer sheath, the inner catheter having a first portion and a second portion; and a snare wire movably disposed through the inner catheter for retrieval of the implant in the body vessel; and an implant retrieval frame for advancement of the retrieval device to snare the implant, the frame comprising: a first arm having a first handle end and a first pivot end; a second arm having a second handle end and a second pivot end, the second pivot end connected to the first pivot end defining a common pivot axis about which the first and second arms pivotally move; and a connector to which the retrieval device is attached, the connector being configured to cooperate with the first and second arms to translate pivotal movement of one of the first and second arms to linear movement of the retrieval device relative to the pivot axis, the connector comprising a movable body connected to the first and second arms so that the connector linearly moves when the arms pivotally move relative to the pivot point, the connector further comprising first and second receivers to which the retrieval device is attached, the first receiver being connected to the first and second arms at the pivot point, the second receiver being connected to the movable body so that the connector linearly moves relative to the pivot point, the connector being configured to linearly extend when one of the first and second handles pivots towards the other relative to the pivot point and linearly retract when one of the first and second handles pivots away from the other relative to the pivot point, the first and second handles being configured to pivot towards each other to move the movable body and extend the second receiver linearly from the pivot point, wherein the first and second handles are configured to pivot away from each other to retract the second receiver towards the pivot point to allow control of linear movements of the outer sheath, the inner catheter, and the snare wire of the assembly.
