Publication number: 20230338048Abstract: Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.Type: ApplicationFiled: November 16, 2022Publication date: October 26, 2023Inventors: Earl Howard Slee, Thomas Wilder, III, Thomas McCarthy, Mark Philip Ashby, Sanjay Shrivastava

Publication number: 20230285030Abstract: Devices, systems, and methods for delivering an expandable member to a treatment site within a blood vessel are disclosed herein. According to some embodiments, a delivery system includes a core member and a coupling assembly carried by the core member. The coupling assembly may include an engagement member configured to engage an inner surface of an expandable member extending over the coupling assembly to facilitate delivery of the expandable member from an elongated shaft and/or resheathing of the expandable member into the elongated shaft. The engagement member can be movable between a radially compressed configuration and a radially expanded configuration.Type: ApplicationFiled: February 27, 2023Publication date: September 14, 2023Inventors: Mark Philip Ashby, Danyong Zeng, Sydney Loan-Phuong Ngo

Publication number: 20230277187Abstract: Expandable devices for occluding bifurcation aneurysms are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be deployed at a treatment site including blood vessel bifurcation of a human patient so that the mesh extends across a neck of an aneurysm and prevents or limits blood flow through the mesh and into the aneurysm. The mesh can comprise one or more circumferentially discontinuous portions so that, when the device is deployed at the treatment site, the device does not substantially impede flow from a parent blood vessel to two or more branching blood vessels. Systems and methods for delivering an expandable device of the present technology are also disclosed herein.Type: ApplicationFiled: March 2, 2022Publication date: September 7, 2023Inventors: Mark Philip Ashby, Ashok Nageswaran, Eric Mintz, Gaurav Girdhar, Ujwal Ramesh Jalgaonkar, John Wainwright

Publication number: 20230240686Abstract: Devices for treating vascular defects and associated systems and methods are disclosed herein. In some embodiments, for example, an occlusive device for treating an aneurysm includes a tubular structure having a first end portion with a first opening, a second end portion with a second opening, and a mesh surface extending between the first and second end portions. The occlusive device also includes a plurality of spiral struts coupled to the first end portion of the tubular structure and extending over the first opening. When the occlusive device is deployed within the aneurysm, the tubular structure and the plurality of spiral struts can be configured to self-expand such that the plurality of spiral struts span a neck of the aneurysm substantially within a single plane and the mesh surface of the tubular structure engages a wall of the aneurysm near the neck.Type: ApplicationFiled: February 3, 2022Publication date: August 3, 2023Inventor: Mark Philip Ashby

Patent number: 8864790Abstract: An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.Type: GrantFiled: April 16, 2007Date of Patent: October 21, 2014Assignee: Covidien LPInventors: Brian Michael Strauss, Earl Howard Slee, Ramon Torres Carrillo, Khoa Dang Vu, William Robert Patterson, Jessica Liang, Richard Stephen Bein, Todd Jeffrey Hewitt, Stacy Leon Faught, Vince Divino, Darrell Christopher Drysen, Mark Philip Ashby, Justin Arthur Klotz, Maria De Jesus Sanson, Scott William Brennan, Lawrason Charles Wilbur, Lester Eugene Oestreich
