Abstract:
This disclosure is directed primarily to a stent for use in the trachea. The stent has a nominally deployed state, an axially extended state and an axially compressed state. The stent has a length. In the axially extended state, the length is at least 20% greater than in the nominally deployed state.
Abstract:
An endoluminal stent and associated methods for placing the endoluminal stent in a lumen of a trachea of a patient. The stent includes an elongate framework having a first open end, a second open end opposite the first open end, and a lumen extending from the first open end to the second open end. The elongate framework includes a first edge extending from the first open end to the second open end, a second edge extending from the first open end to the second open end, and an opening between the first edge and the second edge extending from the first open end to the second open end such that the stent has a C-shaped cross-section. The stent may be implanted in a trachea with the opening positioned along a posterior wall of the trachea adjacent the trachealis muscle.
Abstract:
Tracheal stents may include a plurality of wave form structures each extending radially about the support structure, a plurality of axial loop members extending axially between adjacent wave form structures and a polymeric covering disposed thereover. Tracheal stents may include an expandable metal structure and a plurality of spacer fins extending above an outer surface of the expandable metal structure. The plurality of spacer fins may be formed of a material different than that of the expandable metal structure.

Abstract:
An endoprosthesis, such as a stent, having anti-migration features. The endoprosthesis includes an expandable tubular framework including a plurality of strut rows and a plurality of connectors extending across interstices between adjacent strut rows and interconnecting adjacent strut rows. The strut rows have an outer diameter in an expanded state and the connectors extend radially outward beyond the outer diameter of the strut rows in the expanded state. The connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis in the body lumen. The endoprosthesis may include a polymeric cover covering the strut rows and spanning the interstices between adjacent strut rows, while a space between the connectors and the strut rows to which the connectors are interconnected with is devoid of the polymeric cover to permit tissue ingrowth around the connectors.
Abstract:
An implantable medical device may include a stent being structured and arranged to increase in length from a deployed length to an extended length; and a cover 120 disposed around an exterior surface of a covered section of the stent, wherein a second portion of the cover overlaps a first portion of the cover, wherein an adhesive is disposed between the first portion of the cover and the second portion of the cover. Methods of using an implantable medical device and methods of making an implantable medical device are disclosed.
Abstract:
A prosthesis that includes a stent comprising a plurality of circumferential bands, a plurality of linking members, at least one anchor, or a prosthesis that includes a stent comprising at least one anchoring section comprising a first circumferential band, a second circumferential band, and at least one anchor. Optionally, the prosthesis further includes at least one cover.
