First Claim
1. An embolectomy device, comprising:
- a clot engaging structure comprising a plurality of interconnected struts forming an open cell structure having an inner lumen, wherein the clot engaging structure is biased to expand, or is otherwise expandable from, a radially constrained configuration to a radially expanded configuration when released from a delivery catheter into a blood vessel; and
a support structure positioned within the inner lumen of the clot engaging structure, the support structure comprising a plurality of connectors connected to respective struts of the clot engaging structure,wherein the connectors are biased to move or otherwise movable from a radially constrained configuration to a radially expanded configuration to thereby cause or otherwise assist and/or facilitate expansion of the clot engaging structure and/or establishing and maintaining an open cell structure thereof when the clot engaging structure is released from a delivery catheter into a blood vessel.
