Abstract
A provided clot extraction system can be used for the removal of clot that may have a wall adherent component. The clot extraction system includes a cover sleeve and a telescoping 5-shaft assembly. A coring element having a blade used for physically breaking down clot is coupled to the shaft assembly. A mesh support element is coupled to the shaft assembly. An open end of a mesh is coupled to the mesh support element and a distal end of the mesh is coupled to the shaft assembly. The mesh is used to collect clot within the vessel, such as the clot that the blade of the coring element separates from the vessel wall. The shape of the coring element or the mesh support element may be altered via the shaft assembly.
Claims23
A system comprising:
- a first shaft;
- a second shaft;
- a third shaft;
- a fourth shaft;
- a fifth shaft;
- a support element coupled to the second and third shafts;
- a mesh having an open end and a second end, wherein the open end of the mesh is coupled to the support element and the second end of the mesh is coupled to the first shaft;
- and
- a coring element coupled to the fourth and fifth shafts, wherein the coring element includes a cutting edge.
A system comprising:
- a telescoping shaft assembly including a plurality of shafts;
- a coring element coupled to the telescoping shaft assembly, wherein the coring element includes a cutting edge;
- a support element coupled to the telescoping shaft assembly and spaced apart from the coring element along the telescoping shaft assembly;
- and
- a mesh coupled to the support element;
- wherein the telescoping shaft assembly, the coring element, and the support element are configured such that the coring element is movable relative to the support element in a direction parallel to an axis extending through the telescoping shaft assembly.
An apparatus comprising:
- a plurality of shafts;
- a mesh comprising a distal end coupled to a first shaft of the plurality of shafts and an open end coupled to a second shaft of the plurality of shafts;
- and
- a coring element comprising a first end coupled to a third shaft of the plurality of shafts and a second end coupled to a fourth shaft of the plurality of shafts, wherein the coring element includes a cutting edge;
- wherein:
- the open end of the mesh faces the coring element, and
- the cutting edge of the coring element faces away from the mesh.
