Publication number: 20200269013Abstract: A tubular sheath for enclosing an expandable balloon attached to the distal portion of a catheter encloses and protects the expandable balloon. The tubular sheath is configured to be slidable and removable from the catheter. The tubular sheath may include a longitudinal splitting element that is removable as a result of a force applied to the longitudinal splitting element. The longitudinal splitting element is configured to split the wall of the tubular sheath in response to the force. Alternatively, the tubular sheath may include a gripping portion that has relatively poor cohesive strength to adjacent portions of the tubular sheath. The tubular sheath is configured to be removable in response to a force applied to the gripping portion.Type: ApplicationFiled: May 13, 2020Publication date: August 27, 2020Inventors: John Wilson Traxler, Michael Baldwin, Joseph Duffy, John Kantor, Tony Le, Asim Malik, Susan Peterson, Emily Schoenhoff, Eric Hallberg, Steven Holt, Erik Svensson, Ronan Cleary, Sameer Singh, Steven Holmgren, Janet Komatsu, Traci Colgan, Gregory Hopper, Marcel Fuhrer

Patent number: 10668255Abstract: A medical device includes a catheter, an expandable balloon on the distal portion of the catheter, and a sheath that is configured to enclose and protect the expandable balloon. The sheath extends within a sheath lumen of the catheter and out from the catheter through a distal opening of the sheath lumen. When in a deployed configuration, the sheath extends proximally to enclose at least a portion of the expandable balloon. The sheath may be axially movable within the sheath lumen of the catheter to actuate from the deployed configuration to a retracted configuration. In moving to the retracted configuration, the sheath may expose the outer surface of the expandable balloon.Type: GrantFiled: January 19, 2018Date of Patent: June 2, 2020Assignee: MEDTRONIC VASCULAR, INC.Inventors: John Kantor, Claudio Silvestro, Shashank Raina

Publication number: 20170020700Abstract: A method of forming a stent includes the steps of forming a composite member into a stent pattern, forming openings through an outer member of the composite member, processing the composite member to remove a portion of the composite member without adversely affecting the outer member, and swaging the outer member to create a plurality of lumens. The composite member may be formed of an outer member with an hourglass-shaped inner member, wherein the processing step removes the inner member and the swaging step forms two lumens from the hourglass shaped cavity. The composite member may be formed of an outer member, an inner member, and an intermediate member, wherein the processing step removes the intermediate member and the swaging step presses portions of the outer member into contact with the inner member to form two lumens separated by the inner member.Type: ApplicationFiled: August 1, 2016Publication date: January 26, 2017Inventors: Ryan Bienvenu, John Kantor
