A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

Apparatus for loading and delivering a stent

Embodiments of the invention include an endoscope including a distal chamber and related methods of use, for example, with an endoscopic instrument.

Medical devices including distal chamber

Embodiments of the invention include an endoscope including multiple lumens for tissue acquisition and removal and related methods of use.

Endoscopes having multiple lumens for tissue acquisition and removal and related methods of use

The invention relates to an implantable radiopaque stent adapted to be disposed in a body lumen. In one aspect of the invention, a plurality of elongate filaments including one or more radiopaque filaments are arranged to form a hollow tubular structure having a tubular wall that defines an inner surface and an outer surface and opposing first open end and second open end. One of the open ends of the stent is formed by an intersection of adjacent filament ends. A radiopaque compound is applied to the intersection, the radiopaque compound comprising radiopaque material and polymeric material. The radiopaque compound and radiopaque filament provide improved external imaging of the tubular structure on imaging equipment.

Radiopaque compositions, stents and methods of preparation

Endoscopes including distal chamber and related methods of use

According to an aspect of the present invention, a stent is provided, which contains at least one filament that has a longitudinal axis and comprises a bioabsorbable polymeric material. Polymer molecules within the bioabsorbable polymeric material are provided with a helical orientation which is aligned with respect to the longitudinal axis of the filament. The stent is at least partially bioabsorbed by a patient upon implantation or insertion of the stent into the patient.

Bioabsorbable stents with reinforced filaments

The present invention is directed to an endoscopic stent delivery device. The device includes an endoscope having an elongate shaft including a proximal end, a distal end, an outer wall and a longitudinal working channel through the elongate shaft defining an inner wall of the elongate shaft; a stent juxtaposingly disposed to a distal portion of the inner wall; and an inner tubular member slidably disposed within the working channel and having a stent holding member engaging an interior portion of the stent for releasably securing the stent to the distal portion of the inner wall. The device may further include a viewing device disposed at the distal end of the endoscope and/or an illuminating device disposed at the distal end of the endoscope.

Endoscope with preloaded or preloadable stent

An endoprosthesis comprising a stent, a cover fully covering the stent wherein the cover has variable porosity in the radial direction; and an adhesion layer connecting the stent to the cover. Another aspect of the invention is a method of implanting an endoprosthesis which includes a stent, providing a cover with variable porosity in the radial direction, connecting the stent to the cover with an adhesion layer to form a covered stent, and implanting the covered stent within a body lumen of a patient.

Composite stent with inner and outer stent elements and method of using the same

The present invention relates to stent structures having improved migration resistance. In particular, the invention relates to mesh stents, such as braided or twisted stent designs, where at least a portion of the stent is folded back over itself to form a multi-layered stent device. Such multi-layered portions provide for migration resistance, among other advantages.

Continuous double layered stent for migration resistance

A stent delivery system comprising an elongate inner structure, a tubular endoprosthesis holder supported on said elongate inner structure and in coaxial relation therewith, said endoprosthesis holder comprising, the endoprosthesis holder fixed in a coaxial relationship to said elongate inner structure, the endoprosthesis holder comprising a proximal connector structure having an outer surface, a distal connector structure having an outer surface and an intermediate connector structure having an outer surface extending between the proximal and distal connector structure, the outer surface of the at least one of the proximal connector structure, the distal connector structure or the intermediate connector structure comprising at least one outward protrusion.
