Publication number: 20190314140Abstract: A stent device including a stent frame encapsulated by a first graft member and a second graft member. The first graft member can be bonded to the second graft through a plurality of gaps in the stent frame. The stent device also includes an expansion portion that elongates when the stent device is transitioned from a straight configuration to a bent configuration in order to maintain a substantially constant effective cross-sectional area along a longitudinal axis of the stent device in the bent configuration.Type: ApplicationFiled: June 26, 2019Publication date: October 17, 2019Inventors: Debra A. Bebb, Sandra M. Cundy, Jurgen Dorn

Patent number: 10335266Abstract: A stent device includes a first graft member, a second graft member and a stent frame defining a central axis. The frame has an abluminal surface engaged with the first graft member and a luminal surface engaged with the second graft member such that the first graft member and the second graft member encapsulates the stent frame along the length of the central axis. The stent frame includes a configuration where the stent frame is disposed on a curvature such that the abluminal surface has a radius of curvature of approximately 20 millimeters about a center of the curvature and the luminal surface defines a substantially constant effective cross-sectional area at any portion generally transverse to the central axis of the stent frame disposed about the curvature.Type: GrantFiled: October 20, 2016Date of Patent: July 2, 2019Assignee: C. R. Bard, Inc.Inventors: Debra A. Bebb, Sandra M. Cundy, Jurgen Dorn

Patent number: 5667523Abstract: A dual supported intraluminal graft comprising a biocompatible flexible layer sandwiched between two structural support layers. The preferred embodiment comprises a first structural support, such as a stent, which is concentrically retained within a tubular shaped PTFE graft which is concentrically retained within a second structural support, such as a stent. The ends of the PTFE graft may be folded back onto the outer surface of the second structural support thereby forming flaps. Upon radial expansion of the preferred embodiment, the stent/graft/stent assembly forms inseparable layers.Type: GrantFiled: April 28, 1995Date of Patent: September 16, 1997Assignee: Impra, Inc.Inventors: Anne Nina Bynon, Sandra M. Cundy, Rajagopal R. Kowligi
