  • Publication number: 20230062684
    Abstract: An intravascular thrombus retraction device includes: wires that are compressible into a compact cylindrical form within a catheter and are self-expandable into a wire mesh web with at least some parallel wires forming openings in the wire mesh sufficient to allow fluid passage and small enough to filter particles of at least 0.001 mm, a base of the wire mesh web connected to radial ring-shaped structure supporting and maintaining an opening in the base of the wire mesh and forming a thrombus capture volume, and the radial ring-shaped structure being compressible into the catheter and being self-expandable or expandable by struts when free of compressive forces within the catheter to open up into an open, expanded, radial ring-shaped structure which maintains the opening in the opening in the base of the wire mesh.

  • Publication number: 20220087694
    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.

  • Publication number: 20220054153
    Abstract: An intravascular thrombus retraction device and method utilizing wires compressible into a compact form within a catheter and are self-expandable into a wire mesh web with fluid-penetrable openings in the wire mesh small enough to filter clot particles. A base of the wire mesh web is connected to a radially ring-shaped structure supporting and maintaining an opening in the base of the wire mesh and forming a thrombus capture volume. The ring-shaped structure is compressible into the catheter and is self-expandable when free of compressive forces within the catheter to open up into the open, expanded ring-shaped structure, maintaining the opening in the opening in the base of the wire mesh.
