Abstract
An obstruction removal device is described, having one or more engaging members which can engage portions of the clot. The one or more engaging members have a collapsed, delivery state, and an expanded, deployed state.
Claims20
A clot retrieval device, comprising:
- a set of engaging members having at least one engaging member, wherein each engaging member comprises a plurality of strut elements positioned between a proximal and a distal end of the engaging member;
- wherein each engaging member comprises a subset of diamond strut elements having at least a first approximately diamond shape and a second approximately diamond shape,
- wherein each engaging member comprises a subset of twisted strut elements having at least one twisted strut element that is not longitudinally aligned relative to a proximal-distal longitudinal axis between the proximal and distal ends of each engaging member;
- and
- wherein the subset of twisted strut elements is positioned between the first and second approximately diamond shapes.
2 more elements
A clot retrieval device, comprising:
- a set of engaging members having at least one engaging member, wherein each engaging member comprises a plurality of strut elements coupled to a proximal and a distal end of the engaging member;
- wherein each engaging member comprises a proximal subset of strut elements having a first strut density, a distal subset of strut elements having a second strut density, and a central subset of strut elements positioned between the proximal and distal subsets of strut elements and having a third strut density less than the first strut density and less than the second strut density,
- wherein the central subset of strut elements includes at least one strut element that is not longitudinally aligned relative to a proximal-distal longitudinal axis between the proximal and distal ends of each engaging member.
A clot retrieval device, comprising:
- an engaging member having a plurality of struts forming at least a first diamond shape and a second diamond shape and at least one longitudinally unaligned strut positioned between the first diamond shape and the second diamond shape, and
- wherein the longitudinally unaligned strut is not an edge of any diamond shape.
