Vascular thrombectomby apparatus and method of use
First Claim
1. An apparatus comprising:
- a frame having a proximal and a distal end constructed from a super-elastic material;
a membrane attached to the frame;
a separation edge attached to the proximal end of the frame; and
at least one deployment section disposed along the separation edge and having substantially the same cross sectional area as the separation edge wherein the deployment section allows for elastic deformation of the frame and the separation edge.

Abstract
An apparatus is provided for removing matter from within a conduit. The apparatus generally comprises a separation edge attached to a wire at its proximal end, a frame attached to the distal end of the separation edge, and a membrane attached to the wire and disposed over the frame enclosing its interior. The membrane generally comprises a net constructed from a vaporized metal deposited on a mandrel. Alternatively, the membrane may comprise a braided tube constructed from wire. The apparatus may be employed as a filter or as a means for actively dislodging matter from the wall of a conduit. When employed as a filter, the apparatus is positioned downstream of the matter where it ensures that matter does not escape downstream as it is being removed. When employed to actively remover matter from a conduit, the apparatus is positioned downstream of the matter. The apparatus is then pulled proximally whereby it engages the matter and dislodges it from the wall of the conduit

18. An apparatus comprising:
-
a frame constructed from a super-elastic material the frame comprising a plurality of struts at its distal end; a first and a second member attached together at their distal and proximal ends having an inlet there between, said members having an optimal shape for maintaining apposition with the wall of a conduit into which said apparatus is inserted; a wire attached to the proximal end of the first and second members for deploying the apparatus from a sheath whereby the apparatus is expanded; a permeable membrane having an opening at its proximal end and being attached to the wire and being disposed over the frame; and wherein the first and second members are attached at their distal ends to at least two of said plurality of struts such that the internal angles between the members and between the struts are acute allowing the frame and members to elastically recover when deployed from the sheath; and - View Dependent Claims (19, 20, 21, 22)
