ABSTRACT:
A percutaneous thrombolytic device, also referred to herein as a percutaneous mechanical fragmentation catheter system, that includes a wire cage or basket attached to a rotational drive motor. The fragmentation basket, ensheathed in an outer catheter, is introduced into the clotted graft or vessel via an introducer sheath. When deployed, the basket will automatically conform to the inner dimensions of the vessel lumen. The rotating basket is slowly withdrawn through the clotted graft, mechanically fragmenting the clot. The fragmented, homogenized debris can be flushed into the venous system or aspirated.
