Hybrid thrombectomy device and process

Abstract

The disclosed embodiments generally relate to hybrid thrombectomy devices and processes using such devices. In an exemplary embodiment, the disclosure provides a thrombectomy device to extract a thrombus from a body lumen. The device includes a retraction catheter (150) having a proximal end and a distal end, the retraction catheter configured for insertion into the body lumen; a retracting wire (160) movably positioned inside the retraction catheter, the retraction wire further includes: a plurality of struts (170) coupled to the distal end of the retracting wire at a first end of each of the plurality of struts; a collapsible ring (180) coupled to the second end of each of the plurality of struts; and a collapsible web (190) coupled to the ring and configured to expand into a basket when extended beyond the distal end of the retraction catheter. The collapsible web can be configured to fold into a substantially linear structure to movably fit within the retraction catheter. In addition, an Aligner (1120) structure can be deployed to enforce equidistant position of the struts, preventing the struts, ring and web from collapsing along the side of the clot when retracting the device.
