A medical device for inserting into a hollow organ of the body, said medical device having a compressible and expandable lattice structure made of webs, which are integrally connected to each other by web connectors and which bound closed cells of the lattice structure, wherein the web connectors each have a connector axis extending between two cells which, in a longitudinal direction of the lattice structure, are adjacent to each other. During the transition of the lattice structure from the production state to a compressed state, the web connectors rotate in such a way that an angle between the connector axis and a longitudinal axis of the lattice structure changes, in particular increases, during the transition of the lattice structure from a completely expanded production state to a partially expanded intermediate state.

A biodegradable stent prosthesis formed from a degradable material, having a plurality of luminal, abluminal, and side surface regions, wherein a surface portion extending between the abluminal and luminal surface region of at least some structural elements is convex.

A stent comprises a plurality of undulating circumferential portions, each circumferential portion comprising alternating peaks and valleys; and a plurality of longitudinally extending portions connecting the plurality of undulating circumferential portions. Each of the plurality of longitudinally extending portions contains a first longitudinally extending strut and a second longitudinally extending strut circumferentially offset with respect to the first longitudinally extending strut. The first longitudinally extending strut and the second longitudinally extending strut are interconnected by a connecting portion. Circumferentially adjacent first longitudinally extending struts in a pair of circumferentially adjacent longitudinally extending portions are circumferentially spaced at a first distance and circumferentially adjacent second longitudinally extending struts in the pair of circumferentially adjacent longitudinally extending portions are circumferentially spaced at a second distance. The first distance is greater than the second distance. The present stent has a very desirable balance of conformability and flexibility while obviating or mitigating crashing, out of tubular configuration and other problems (as discussed herein).

Polymeric composite stents reinforced with fibers for implantation into a bodily lumen are disclosed.

A stent has one or more redundant crests for a ring. The redundant crest is located at a Y-crown for a peak-to-valley type stent pattern in one example. The stent may also have frangible bridges for connecting links. The stent's radial stiffness decreases when a redundant crest fractures and its axial and bending stiffness decreases when a frangible bridge breaks.

A stent that includes a plurality of quill filaments. Each quill filament includes filament material, a surface, and a plurality of quills. Each quill has a tip, a body, and a base where the body extends from the base to the tip. The quill filaments can be interwoven to form the stent or the quill filaments can be engaged to the framework of a stent.

A prosthesis is provided for a variety of medical treatments. The prosthesis may include an expandable tubular frame structure and a covering disposed along the frame structure. A proximal liner may be situated along a proximal end of the frame, a distal liner may be situated along a distal end of the frame, and an intermediate liner may be between the proximal liner and the distal liner along the frame. The intermediate liner comprises an extended layer that meets and bonds to the proximal liner and the distal liner at their respective ends. A method of manufacturing the prosthesis is also provided.

A stent includes a tubular body possessing a plurality of gaps. The tubular body includes a plurality of circumferentially extending linear struts. The stent includes a plurality of links connecting the linear struts. At least one of the links has first and second connection portions. The first connection portion is integrally formed with one strut, and the second connection portion is integrally formed with an adjacent strut. The stent includes a biodegradable material between the first connection portion and the second connection portion to connect the first and second connection portions to each other. The biodegradable material restrains the one strut and the adjacent strut from moving to their original shapes. The first and second connection portions move relative to one another in a separation direction when a connection by the biodegradable material is released so that the original shapes of the struts are restored.

A method of crimping a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the maker support structures.

An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.
