A medical device may include a catheter, an expandable member, a cover, and an actuator. The catheter may include a longitudinal axis, proximal and distal ends, and a cover lumen extending from the proximal to the distal end. The expandable member may include proximal and distal ends and may be disposed on a distal section of the catheter. The cover may include a first region that may be disposed along the expandable member, and a second region that may extend along a length of the catheter beyond the proximal end of the expandable member towards the proximal end of the catheter. A first end of the cover may invert into the cover lumen. The actuator may be coupled to the first end of the cover and configured to move the first end of the cover towards the proximal end of the catheter along the longitudinal axis of the catheter.

Multiple inflation endovascular medical device

The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, and an end cap having one or more protrusions extending therefrom. The protrusions may assist in retraction of end cap into an outer sheath, such as an introducer sheath. In some examples, the protrusion includes fins. In some embodiments, the endoprosthesis delivery system further includes a covering member disposed about the endoprosthesis. The protrusions may support the covering member, which may extend beyond the distal end of the endoprosthesis and onto the end cap. In some embodiments, the end cap comprises a tapered profile, which may assist in retraction of the catheter tip and end cap into an outer sheath.

Endoprosthesis delivery system with improved retraction

An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.

Balloon expandable endoprosthesis

A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.

Stented vascular graft

An open stent (a stent having open space through its thickness at locations between the ends of the stent), incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are preferably longitudinally oriented.

Stent having flexibly connected adjacent stent elements

The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, a covering member disposed about the endoprosthesis, a tip, and an end cap. The tip and end cap can be integral to each other. The covering member can extend beyond the distal end of the endoprosthesis and onto the end cap. The end cap can comprise a tapered profile, which may assist in retraction of the catheter tip and end cap into an outer sheath. The end cap can further comprise one or more fins.
