Patent number: 9452068Abstract: An expandable slide and lock stent comprises a tubular member that can be expanded from a collapsed state to an expanded state. The tubular member can comprise a reversing helical backbone and at least one rail member extending from the helical backbone in a circumferential direction. The backbone can have at least one engagement element that can be configured to receive a rail member to form the tubular member. In some embodiments, the reversing helical backbone can comprise a plurality of discrete segments having a variable profile and/or wave form.Type: GrantFiled: August 28, 2013Date of Patent: September 27, 2016Assignee: REVA Medical, Inc.Inventors: Eric Schmid, Keith Weier, Keith A. Esser, Steven C. Howard, John Hobson, Craig Bonsignore

Patent number: 9314354Abstract: Expandable medical implants for maintaining support of a body lumen are disclosed. These implants comprise an axially-radially nested, diametrically expandable, moveable vascular device for enlarging an occluded portion of a vessel. The device can be configured to allow for motion such as translating and/or slide and lock. One advantage of the axially-radially nested stent is that it maintains the expanded size, without significant recoil.Type: GrantFiled: May 10, 2013Date of Patent: April 19, 2016Assignee: Reva Medical, Inc.Inventors: Andrew Morris, Jeffrey T. Sheriff, Keith Esser
