Publication number: 20220142800Abstract: A stent delivery system can include a core member, first and second restraints, and a stent engagement component. The core member can have a distal segment. The first and second restraints can be coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap. The first and second restraints can each have an outer profile that tapers radially inwardly in directions away from the gap. The stent engagement component can be at least partially disposed in the axial gap between the first and second restraints such that the component is slidably and rotatably coupled to the core member distal segment.Type: ApplicationFiled: January 20, 2022Publication date: May 12, 2022Inventors: Kenneth Brown, Ghislain Sema, Michael Losordo, Evan Epstein, Gabriel Newell, Andy Huynh, Lawrence Farhat

Patent number: 10383644Abstract: The medical device can comprise a manipulation member, a mechanical thrombectomy apparatus attached to a distal end of the manipulation member, and flow-restricting apparatus attached to the manipulation member to a location proximal to the mechanical thrombectomy apparatus. A method, for retrieving thrombus from a blood vessel, can comprise advancing a single elongate delivery member carrying a mechanical thrombectomy apparatus and a flow-restricting apparatus through a catheter to the blood vessel, expanding the thrombectomy apparatus and capturing the thrombus with the thrombectomy device, expanding the flow-restricting apparatus to at least partially occlude blood flow toward the thrombus, retracting at least a portion of the thrombectomy apparatus into the flow-restricting apparatus, and retracting the flow-restricting apparatus and the thrombectomy apparatus into the retrieval catheter.Type: GrantFiled: October 17, 2013Date of Patent: August 20, 2019Assignee: Covidien LPInventors: Masoud Molaei, Evan David Epstein, Garrett Johnson, Ghislain Sema
