Patent number: 11871947Abstract: A clot removal device has a segment that has two main struts that serve as a frame for holding a plurality of secondary struts. Each of the two main struts has a proximal end that is connected at a proximal point of the segment and extends along a generally circumferential path, with each main strut terminating at a separate connecting point that is distal from the proximal point. The connecting points are connected to each other to form a generally tubular structure defining an inner lumen. The plurality of secondary struts forms a lattice of cells, with each cell surrounded by four secondary struts. Two generally straight distal struts are connected to the lattice of cells at a distal end of the segment, and are connected to each other to form a distal point. A distal opening is defined by the cells adjacent the distal struts, the distal opening communicating with the lumen and terminating at the proximal point.Type: GrantFiled: July 30, 2020Date of Patent: January 16, 2024Assignee: NeuroVasc Technologies, Inc.Inventors: Michael Losordo, Jianlu Ma

Patent number: 11690741Abstract: Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.Type: GrantFiled: September 16, 2020Date of Patent: July 4, 2023Assignee: COVIDIEN LPInventors: Anh Cam, Michael Losordo, Jianlu Ma, Luong Nguyen, Sanjay Shrivastava, John Wainwright, Xiaoling Zhao

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: 10271978Abstract: A medical device, for insertion into an anatomical vessel, can include a sheath, a delivery wire, and a frame or vessel-engaging member. The delivery wire can have a first stop, a second stop, and a coupling area between the first and second stops. The coupling area can be disposed within and movable relative to the sheath. The frame or vessel-engaging member can have a matrix of cells, first and second tapered sections, and interlocking members. The interlocking members can be attached to the tapered sections. The interlocking members can be releasably coupled to the delivery wire at the coupling area with the interlocking members surrounded and held in the coupling area by the sheath. The interlocking members can be movable relative to the sheath, and the interlocking members can separate from each other when the interlocking members are positioned distal to the sheath.Type: GrantFiled: February 5, 2016Date of Patent: April 30, 2019Assignee: Covidien LPInventors: John Wainwright, Michael Losordo

Patent number: 10123804Abstract: Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.Type: GrantFiled: June 24, 2016Date of Patent: November 13, 2018Assignee: COVIDIEN LPInventors: Anh Cam, Michael Losordo, Jianlu Ma, Xiaoling Zhao
