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

Patent number: 9486608Abstract: A microcatheter for delivering embolic agent to a vascular site is provided. The microcatheter has a biocompatible or biocompatible and biodegradable tip which can be detachably engaged to the microcatheter body by a thermoplastic sleeve. Once the embolic agent is delivered to the desired vascular site, the tip of the microcatheter is often entrapped within the mass of the liquid embolic fluid. Using the microcatheter, the clinician can retract the microcatheter at a predetermined retraction force thereby disengaging the tip from the microcatheter body allowing for easier removal of the microcatheter.Type: GrantFiled: April 9, 2013Date of Patent: November 8, 2016Assignee: Covidien LPInventors: Karl Sutherland, Earl Howard Slee, Vitas Jonas Sipelis, Mark Anthony Siminuk, Brian Michael Strauss

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
