Patent number: 8523936Abstract: 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: April 8, 2011Date of Patent: September 3, 2013Assignee: REVA Medical, Inc.Inventors: Eric Schmid, Keith Weier, Keith A.

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

Patent number: 8460363Abstract: 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: July 29, 2011Date of Patent: June 11, 2013Assignee: Reva Medical, Inc.Inventors: Andrew Morris, Eric Schmid, Jeffrey T.

Patent number: 8133959Abstract: Inherently radiopaque side-chain crystallizable polymers (IRSCCP's) are useful in various medical applications. An example of a IRSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer, the heavy atoms being present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes a IRSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product.Type: GrantFiled: May 5, 2011Date of Patent: March 13, 2012Assignee: REVA Medical, Inc.Inventors: Donald K Brandom, Joan Zeltinger, Eric V Schmid, Joseph J Mallon

Publication number: 20110213456Abstract: Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product.

Publication number: 20110172759Abstract: The invention relates generally to expandable medical implants for maintaining support of a body lumen and, in particular, to an axially nested, diametrically expandable, slide and lock vascular device for enlarging an occluded portion of a vessel. The axially nested vascular device desirably achieves both competitive crossing profiles while maintaining other key features, such as, for example, radial strength and luminal patency. The collapsed profile can also be made very thin without compromising radial strength. Thus, the vascular device can advantageously be deployed in small and difficult to reach areas or vessels. The axial nesting substantially eliminates radial overlap between mating structural elements thereby desirably allowing for a low, uniform profile.Type: ApplicationFiled: March 28, 2011Publication date: July 14, 2011Applicant: REVA MEDICAL, INC.Inventors: Eric V. Schmid, John D. Nguyen, Orlando Padilla, Andrew Morris, Daniel Moore, Thomas R. Jackson
