Abstract:
1. A self-expandable apparatus for removal of a thrombus in a blood vessel, comprising: a tubular structure having a proximal end and a distal end, the structure having (a) a distal portion comprising a first plurality of cells, (b) a proximal portion comprising a second plurality of cells,(c) a first diameter at the distal end, and (d) a second diameter at the proximal end, the distal portion having a distally widening taper at a distal end portion of the distal portion such that the first diameter is greater than the second diameter, the apparatus further comprising a connection point located at a proximal end of the proximal portion wherein the proximal portion converges at the connection point, the apparatus further comprising two edges extending parallel to a longitudinal axis of the structure, wherein the structure is configured to assume an expanded configuration at the place of implantation, and wherein the structure is configured to be modified into a volume-reduced configuration for insertion within a microcatheter, the volume-reduced configuration having a smaller cross-sectional dimension than the expanded configuration, the two edges being overlapped in the volume-reduced configuration, wherein the structure is configured to expand into the thrombus when transitioning from the volume-reduced configuration to the expanded configuration.
