Publication number: 20230149148Abstract: A system used to entrap clots in arteries, such as cerebral arteries, between the artery wall and an external surface of a stent to provide restoration of blood flow therethrough that includes a stent forming an annular wall that defines a set of openings, and an expansion member extendable through the stent to place a distal portion thereof distal to the stent. The stent is advanced into a clot disposed within a vessel and transitioned to an expanded configuration such that the annular wall engages the clot. The expansion member extends through the stent and is transitioned to an expanded state such that a diameter of the distal portion is greater than a diameter of a proximal portion thereof. The expanded distal portion is sized to fill a portion of the vessel to prevent clot fragments from flowing distal to the expansion member.Type: ApplicationFiled: January 5, 2023Publication date: May 18, 2023Inventors: Salvatore MANGIAFICO, Mario MUTO, Mehmet Hakan AKPINAR, Rafal Wojciech LOPALLO, Antonello FAZIO, Scott Edward PARAZYNSKI, Thomas NISSL

Patent number: 9925076Abstract: A stent in the form of a generally tubular body has multiple annularly expandable serpentine elements. The serpentine elements have arcs at the first and second element ends which point in the axial direction of the stent. Annularly expandable serpentine elements which follow one another in the axial direction are connected to one another via connectors which are arranged at the ends of the adjacent elements. The connectors extend in the circumferential direction of the stent in the non-expanded state of the stent and have a curvature in the circumferential direction. In the expanded state of the stent, the curvature is so great in the circumferential direction that the connectors project radially outward beyond the circumference of the serpentine elements.Type: GrantFiled: April 17, 2014Date of Patent: March 27, 2018Assignee: NOVATECH SAInventor: Thomas Nissl
