Abstract
Devices, methods, kits, and methods remove clot material from the vasculature and other body lumens. Expansible baskets may be used as cooperating radially expansible shearing members. Helically oriented struts of each basket may wind in a uniform circumferential direction. The struts can be independently flexible, allowing the shearing members to flex axially together. The inner basket may be rotatably driven and may use an axial pump extending proximally from the shearing members and/or a distal penetrator for advancing into an occlusion which inhibits guidewire access. The struts may slide substantially continuously across each other, and may be sufficiently aggressive for highly effective thrombectomy.
