Abstract: Lumen support devices and methods of their use are provided. A lumen support includes one or more plastically deformable cells having two stable configurations with no stable configurations between the two stable configurations. The lumen support device may be plastically deformed to other stable configurations.

Abstract: A stent may include a connector having a first portion, a second portion, and a third portion positioned between the first and second portions. The connector may be configured to interconnect axially adjacent stent segments. The connector may be further configured such that the third portion severs in response to a threshold amount of axial force, axial foreshortening, and/or cyclic loading or fatigue, in order to predispose the severance of one or more pre-configured connectors in a controlled manner to minimize any potential harm to the surrounding vasculature of a patient.

Abstract: The present invention is directed to bistable cells and their use in devices, particularly medical devices such as stents, clamps and valves. An expandable stent formed of a plurality of bistable cells is described. The stent has two or more stable configurations, including a first stable configuration with a first diameter and a second stable configuration with a second, larger diameter. A valve comprising a bistable cell for use in eliminating incontinence is also disclosed.

Abstract: Expandable biodegradable devices formed of bistable and multistable unit cells for use in devices, such as stents and graft systems, are provided, in which the device has two or more stable configurations, including a contracted configuration and an expanded configuration, the contracted stable configuration having a smaller diameter than the expanded configuration.

Abstract: Vascular prostheses and methods of use are provided, wherein the vascular prosthesis includes a plurality of bistable unit cells configured to form a helical structure. A visualization catheter also is provided for use ensuring accurate measurement of a lesion and ensuring delivery and placement of the vascular prosthesis.
