Abstract

A retrieval system for a medical device includes an access sheath, a clot catch with an attached mesh, and a filter catch having an attached retrieval member. The filter catch is translatable within clot catch, and the clot catch is translatable within the access sheath. The mesh is expandable into engagement with a body vessel during retrieval of the medical device. The mesh captures emboli that are dislodged during retrieval of the device. The device is captured by the clot catch during retrieval, and the clot catch is subsequently captured by the access sheath. The system can further include an inner sheath translatable within the clot catch, with the inner sheath capturing the medical device and the clot catch capturing the inner sheath.
