Deep vein thrombosis thrombectomy device with embolic protection

A thrombectomy device, comprising:

• an elongate shaft having a proximal end and a distal end;
• an expandable structure coupled to the distal end of the elongate shaft;
• and
• a catheter configured to deliver the expandable structure in a collapsed state to a location in a vessel containing a thrombus, wherein
• the expandable structure in an expanded state is rotatable with the elongate shaft to disintegrate the thrombus into fragments, and
• the expandable structure comprises a first end fixedly coupled to the elongate shaft and an unfixed second end freely slidable along the elongate shaft.

A thrombectomy device, comprising:

• an elongate shaft having a proximal end and a distal end;
• an expandable structure coupled to the distal end of the elongate shaft;
• and
• a catheter configured to deliver the expandable structure in a collapsed state to a location in a vessel containing a thrombus, wherein
• the expandable structure in an expanded state is rotatable with the elongate shaft to disintegrate the thrombus into fragments, and
• wherein the elongate shaft comprises a tubular shaft and one or more removable or replaceable sections.

A thrombectomy device, comprising:

• a coring member configured to disintegrate a thrombus in a vessel into fragments;
• and
• a catch member configured to be anchored at a distal side of the thrombus to provide embolic protection,
• wherein the coring member and the catch member are operable independently of each other,
• wherein the coring member is coupled to a shaft, the catch member is coupled to a shaft, and the shaft of the coring member and the shaft of catch member are moveable independently of each other, and
• wherein the shaft of the coring member comprises one or more removable or replaceable sections.
