Patent number: 11864781Abstract: A device for removing a clot from a vessel can have dual layers where an inner expandable body runs within an outer expandable body. The device can have a collapsed delivery configuration, an expanded deployed configuration, and a clot pinching configuration. The inner and outer bodies can be a plurality of cells formed by a network of struts. The openings of the cells align when the device is deployed within the clot, where the radial force from the expanding bodies urges portions of the clot through the openings. The inner and outer bodies can be configured to be selectively translatable relative to each other, so that the portions of the clot in the cell openings can be compressed and gripped when the translation transitions the device to the clot pinching configuration. The translation can be maintained to pinch the clot as it is retrieved from the patient.Type: GrantFiled: September 23, 2020Date of Patent: January 9, 2024Assignees: NEURAVI LIMITED, BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Avi Shalgi, David Vale
