SYSTEM FOR REMOVING A CLOT FROM A BLOOD VESSEL

摘要

A system for removing obstructions from a blood vessel comprises a clot retrieval device and a catheter. The clot retrieval device comprises a clot engaging element attached to the distal end of an elongate shaft. The elongate shaft has a shaft proximal section, a shaft distal section and a shaft intermediate section between the shaft distal and proximal sections. The catheter has a catheter proximal section, a catheter distal section, and a catheter intermediate section between the proximal and distal sections. The maximum diameter of a shaft proximal section is greater than an inner distal lumen of the catheter distal section.

1. A system for removing obstructions from a blood vessel, the system comprising:
a clot retrieval device and a catheter; the clot retrieval device comprising a clot engaging element and an elongate shaft; the clot engaging element having a first collapsed delivery configuration and a second expanded deployed configuration; the elongate shaft having a shaft proximal section, a shaft distal section and a shaft intermediate section between the shaft distal and proximal sections; the clot engaging element being attached to the distal section of the elongate shaft; the catheter having a catheter proximal section, a catheter distal section, and a catheter intermediate section between the proximal and distal sections; the catheter proximal section having an inner proximal lumen and an outer proximal diameter, the catheter distal section having an inner distal lumen and an outer distal diameter; wherein the maximum diameter of the shaft proximal section is greater than the inner distal lumen of the catheter distal section.
