An endovascular system is disclosed. The system includes deployment device and a stent-graft assembly. The stent-graft assembly includes an elongate vessel wall engaging graft portion and a proximal-end self-expanding stent comprising a plurality of terminal portions. The deployment device includes an elongate guide wire catheter adapted to be deployed over a guide wire; a tip at a proximal end of the guide wire catheter. The tip has a proximal nose and a distal receiving zone. The distal receiving zone comprises a plurality of circumferentially spaced apart elongate recesses, each recess receiving at least one of the terminal portions. A trigger wire arrangement retaining the at least one terminal portions within each corresponding recess of the receiving zone is also provided. Retention of the terminal portions within the recess of the receiving zone constrains against relative twisting between the stent-graft assembly and the tip.

A stent-graft comprising a tubular, radially self-expandable, braided structure comprising elongate bioabsorbable filaments, a bioabsorbable adhesive means, and a permanent graft disposed and adhered with the adhesive means to at least a portion of the structure and forming a stent-graft assembly, the permanent graft and the tubular structure are coextensive along at least a portion of the stent-graft.

A prosthesis delivery comprising a rotatable inner cannula and a prosthesis releasably coupled to a proximal end of the inner cannula is disclosed. The inner cannula has a first position in which the prosthesis is retained on the cannula and a second position in which the prosthesis is released. At least one magnet is disposed on the inner cannula. A handle assembly is disposed about a distal portion of the inner cannula, the handle assembly comprising a rotary collar having at least one magnet disposed on the inner surface thereof, wherein the at least one magnet disposed on the rotatable inner cannula and the at least one magnet disposed on the inner surface of the rotary collar comprise a magnetic attraction. The magnetic attraction translates torque from rotation of the rotary collar to rotate the inner cannula from the first position to the second position to thereby release the prosthesis.

A stent delivery system includes a self expanding stent positioned about a distal support segment of a catheter, which includes a proximal segment. A constraint has a wrapped configuration, which has a hollow elongated shape, and an unwrapped configuration, which is a continuous length of a strip. The stent is in contact with, and held in a compressed state by, the constraint in the wrapped configuration, and the stent is in an expanded state out of contact with the constraint in the unwrapped configuration. The constraint may move from the wrapped configuration toward the unwrapped configuration responsive to tension in a control line connected to one end of the strip.

Various systems, devices, and methods for endovascular implants and placement thereof are disclosed. The implants include a proximal implant segment, a distal implant segment, connector struts connecting the proximal implant segment to the distal implant segment, and a side opening between the proximal implant segment and the distal implant segment. The implants can be used to create an arteriovenous fistula or connect one vessel of the body to another by placement of the proximal implant segment and the distal implant segment within the vessels to be connected. The implants can include one or more anchors for securing the implant in place with respect to the vessels of the body it is connecting. The implants can also include a continuous strut or ring at a distal edge of the proximal implant segment. Also disclosed are methods for percutaneous placement of the implants, and a device for percutaneous delivery.

The invention relates to a stent and a system for putting in place a stent. Said stent is used especially for splinting a vein and consists of a braided, tubular supporting member (2) that has a minimum length of 60 mm. The supporting member is braided from one or more wires in such a way that portions of the wire or wires, resp., delimit rhombuses. The disclosed stent is characterized in that in the unloaded state of the stent, the longitudinal size of most of the rhombuses (7) in the longitudinal direction (15) of the stent (1) is not shorter than the transversal size of the rhombuses.

A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.

A stent device delivery system and method of making. The stent device delivery system includes a stent device, an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, and a pull member. The outer sheath may include a first layer and a reinforcement layer that are laminated together, a portion of the pull member captured radially between the first layer and the reinforcement layer. At least a partial length of the captured portion of the pull member may be formed with a varying radial profile.

Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering the stent through an access site and deploying a distal portion of the stent from within an outer sheath. In some cases, the method may further include pushing a proximal portion of the stent from the outer sheath such that upon fully exiting the outer sheath, the proximal portion extends proximally to at least partially cover the access site with the stent. The system for delivering the stent into the body lumen may include a stent, a stent delivery apparatus, and an outer sheath. The system may further include an internal pusher configured to push a proximal portion of the stent from the outer sheath and axially compress the stent such that upon fully exiting the outer sheath, the proximal portion extends proximally to cover the access site.

A delivery catheter includes a tip, a spindle and a lock mechanism. The tip includes a tapered portion and a tip sleeve. The tip sleeve extends proximally and has a lumen. The spindle includes a plurality of spindle pins. The lock mechanism locks the tip sleeve to the spindle to prevent relative longitudinal movement between the spindle and the tip sleeve. The delivery catheter includes a delivery configuration with the tip sleeve covering the spindle pins and a release configuration with a proximal end of the tip sleeve distal of the spindle pins. The lock mechanism locks the prosthesis delivery system in the release configuration. Each spindle pin of the plurality of spindle pins includes a smooth, curved profile.
