Abstract
An intravascular articulating retrieval apparatus may be used to move objects within the vasculature, such as to remove an intravascular filter, tissue and other items from the vasculature. The apparatus has a user interface to manipulate a first and second actuating portion that are coupled to the distal end of the apparatus conduit. A retrieval apparatus may include forceps coupled to the second actuating portion whereby the retrieval actuator opens and closes the forceps for retrieval of an IVF or other device, such as stent or stent graft. An intravascular articulating retrieval apparatus may be used to dissect thrombus from the interior of the vascular wall, move a stent or remove a portion of a stent or stent graft to provide better blood flow or to allow blood flow into a branched vessel.
