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

Publication number: 20220304667Abstract: A device for a tissue channel includes a device frame, a shape memory polymer foam segment coupled to the device frame, and an attachment structure coupled to the device frame. The device frame includes a proximal structure, a distal structure, and an intermediate structure coupled to the proximal structure and the distal structure. The proximal structure is configured to collapse to fit into a delivery structure and expand to block migration of the proximal structure. The distal structure is configured to collapse to fit into the delivery structure and expand to block migration of the distal structure. The intermediate structure is configured to fit in the tissue channel upon device deployment. The shape memory polymer foam segment is configured to compress to fit into the delivery structure and occlude the channel. The attachment structure is configured to attach and detach the device from a delivery guide.Type: ApplicationFiled: June 10, 2022Publication date: September 29, 2022Inventors: Mark A. Wierzbicki, Duncan Maitland, Matthew W. Miller, Andrea D. Muschenborn, Landon Nash, Jason M. Szafron, Todd Landsman
