Abstract
A clot capture system for disengaging a clot 2001 from a vessel wall 2002 and removing the clot 2001 from the vessel 202, includes a clot capture device 2140 for placement on a distal side of a clot 2001. The clot capture device 2140 has a retracted delivery configuration and an expanded deployed configuration. The clot removal device has a proximal support frame 2012, and a distal fiber net 2130. The support frame 2012 has a retracted delivery configuration and an expanded deployed configuration. The proximal support frame 2012 in the expanded configuration defines a proximal inlet mouth for engaging a clot 2001 and a net 2130 for confining the clot 2001. An elongate member facilitates capture and/or withdrawal of a clot 2001 from a vessel 2002. The system also includes a clot debonding device 2091 for placement on a proximal side of a clot 2001. The clot debonding device 2091 has a retracted delivery configuration and an expanded deployed configuration and includes a clot engagement element 2112 which defines a distal abutment in the deployed configuration for urging a clot 2001 into the clot capture device 2140.
