Abstract:
1. A method of treating a thrombus in a vessel, the method comprising: advancing a microcatheter in the vessel comprising crossing a distal end of the thrombus with a distal end of the microcatheter; after advancing the microcatheter, inserting a thrombectomy device in a radially compressed state into the microcatheter, the thrombectomy device comprising a plurality of wires woven to form a textile fabric comprising: after inserting the thrombectomy device into the microcatheter, advancing the thrombectomy device in the vessel and through the microcatheter proximate to the distal end of the microcatheter; after advancing the thrombectomy device, maintaining a location of a proximal portion of the thrombectomy device while proximally retracting the microcatheter, wherein upon advancing out the microcatheter the textile fabric changes from the radially compressed shape to the first shape; after retracting the microcatheter, injecting fluid to expose the textile fabric to the temperature, wherein, upon exposure to the temperature, the textile fabric changes from the first shape to the second shape; while the textile structure is in the second shape, torsionally rasping the thrombectomy device; and after torsionally rasping the thrombectomy device, retracting at a similar rate the microcatheter and the proximal portion of the thrombectomy device.
