Publication number: 20220370086Abstract: An embolectomy device comprised of an expansion unit and a support unit is disclosed. The expansion unit can be actuated in response to one or more external stimuli, and the support unit, located proximately to the expansion unit, provides a force to hold the expansion unit in place and to further induce the expansion unit's radial expansion. The radial expansion of the expansion unit causes the expansion unit to physically contact a blood clot, enabling the blood clot to be removed. In some embodiments, the expansion unit can be fabricated from a shape memory polymer foam. In some embodiments the support unit can be fabricated from any elastic material including, without limitation, shape memory alloys.Type: ApplicationFiled: August 5, 2022Publication date: November 24, 2022Inventors: Jason Szafron, Duncan Maitland, Ward Small, IV, Patrick R. Buckley, Andrea D. Muschenborn
