Publication number: 20150018931Abstract: A graft device can include a graft component and an expandable component that has a longitudinal axis and a coupling portion. The coupling portion has a surface extending radially relative to the longitudinal axis. The graft component also has a portion that is coupled to the surface of the expandable component for securing the graft component relative to the expandable component. For example, the graft component portion can be frictionally engaged between the surface and a member positioned against the expandable component.Type: ApplicationFiled: April 30, 2014Publication date: January 15, 2015Applicant: COVIDIEN LPInventors: Michi E.

Patent number: 8747450Abstract: A method for assembling a stent graft onto a balloon delivery catheter is disclosed. The method includes the steps of: assembling a graft over a stent with attached security rings and inserting the ends of the graft between the stent and the rings; placing the assembled stent graft on the delivery balloon of the delivery catheter; and crimping the stent graft onto the balloon. The stent may include a plurality of axially aligned belts that include a plurality of mid belts, and first and second end belts, where each of the mid belts includes a plurality of circumferentially spaced struts having first and second ends adjoining first sinusoidal-shaped elements, and each of the first and second end belts includes at least about twice the number of circumferentially spaced struts adjoining second sinusoidal-shaped elements. Also disclosed is a stent graft for use in practicing the method.Type: GrantFiled: June 27, 2012Date of Patent: June 10, 2014Assignee: Covidien LPInventors: Michi E. Garrison, Leon V. Rudakov

Patent number: 6520984Abstract: A stent graft assembly for use in placing a stent graft in a vessel of a patient comprising a balloon delivery catheter having a distal extremity and having an inflatable balloon on the distal extremity. A stent graft disposed over the inflatable balloon. The stent graft comprises a stent and a graft in the form of a polymeric sleeve extending over at least a portion of the graft. The graft has first and second ends. First and second expandable security rings are disposed over the first and second ends of the graft and serve to secure the first and second ends of the graft to the stent to prevent inadvertent displacement of the graft with respect to the stent during deployment of the stent graft into the vessel of the patient.Type: GrantFiled: April 28, 2000Date of Patent: February 18, 2003Assignee: CardioVasc, Inc.Inventors: Michi E. Garrison, Leon V. Rudakov
