<p>A percutaneous catheter system is disclosed for mechanically fragmenting thrombus in a vascular conduit. The system has a fragmentation catheter (14) inside an outer introducer sheath (12). A self-expandable fragmentation member (16) is attached to the distal end of the fragmentation catheter. A drive mechanism (10) is attached to the proximal end of the fragmentation catheter by a flexible drive shaft (18) which rotates the fragmentation member in order to break up the thrombolytic material into small particles.</p> |
