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: 9408732Abstract: 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. A plurality of regions of each backbone may have a recessed or “nesting” profile providing for a smaller overall stent profile in a compacted configuration, and improved stent retention as mounted on a balloon catheter.Type: GrantFiled: March 11, 2014Date of Patent: August 9, 2016Assignee: REVA Medical, Inc.Inventors: Keith Weier, Steven C. Howard

Patent number: 9173751Abstract: The invention relates to an expandable stent comprising circumferentially adjacent modules. The modules comprise longitudinally adjacent slide-and-lock radial elements which permit one-way sliding of the radial elements from a collapsed diameter to an expanded/deployed diameter, but inhibit radial recoil from the expanded diameter.Type: GrantFiled: September 13, 2012Date of Patent: November 3, 2015Assignee: REVA MEDICAL, INC.Inventors: Eric V. Schmid, John D. Nguyen, Steven C. Howard, Orlando M. Padilla, Andrew Morris, Robert F. Eisele, Daniel Moore, Thomas R. Jackson, Joan Zeltinger

Patent number: 8512394Abstract: An intraluminal, balloon expandable stent for implantation in a body lumen is disclosed. The present invention provides a lumen support stent with an unobstructed through-lumen for use in a blood vessel. A constraining mechanism is provided for securely maintaining the stent in the collapsed condition during delivery. The stent is preferably formed with a series of interconnected slide and lock mechanisms for permitting movement from a collapsed condition to an expanded condition and inhibiting radial recoil from the expanded condition. The stent may be formed from a shape memory alloy for providing crush-recovery after deployment.Type: GrantFiled: July 26, 2010Date of Patent: August 20, 2013Assignee: Reva Medical Inc.Inventors: Eric V. Schmid, Andrew Morris, John Nguyen, Robert F. Eisele, Steven C. Howard, Orlando M. Padilla, Philip J. Simpson
