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.

An endovascular delivery system for delivering a stent graft within a blood vessel. The delivery system includes a guide member configured to carry the stent graft into the blood vessel and a graft cover configured to cover at least a portion of the stent graft as the guide member is inserted into the blood vessel. The stent graft including a first end and a second end, the first end closer to a proximal end of the endovascular delivery system than the second end. The guide member includes a body having an elongated shape and a non-uniform outer periphery. The non-uniform outer periphery is configured to secure a first end of the stem graft in a first position, relative to a deployment location thin the blood vessel, to hold the first end of the stent graft in the first position as the graft cover is retracted to deploy the stent graft.

A medical device, which may be adapted for delivering and/or recapturing an implantable implant, includes an elongate sheath and a rigid member that is secured relative to the elongate sheath. The elongate sheath includes an inner polymeric liner, an outer polymeric sheath and a reinforcing braid that extends within the outer polymeric sheath. The reinforcing braid includes a plurality of wire ends that extend beyond a distal edge of the rigid member in order to protect the implantable implant from being damaged by the rigid member in the event that the inner polymeric liner becomes damaged.

An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, and forms a lumen therethrough. The mobile external coupling includes a graft material, extends outwardly from the tubular body, and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top that is in flow communication with the body lumen. An annular support wireform is coupled to the mobile external coupling, and is formed into a sinusoidal configuration having a plurality of opposing first crowns and second crowns, the first crowns of the support wireform extending around of the top of the mobile external coupling. The coupling graft material extending between the second crowns of the support wireform and the tubular body is unsupported.

A stent having a main linear strut and at least two secondary struts. The main linear strut includes an outer member and an inner member. A distal end of one secondary strut may be attached to a distal end of the inner member. A proximal end of a secondary strut may be attached to a proximal end of the outer member. The ends of the secondary struts that are not attached to the inner and outer member may be joined. Methods of delivering such a stent and collapsing and withdrawing such a stent are also disclosed.

The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. In a first embodiment, a first proximal apex comprises a bore for receiving a trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

A medical device system may include an elongate shaft having a lumen extending to a distal end of the elongate shaft, wherein a proximal portion of the elongate shaft is configured to disengage from a distal portion of the elongate shaft; a medical device disposed proximate the distal end of the elongate shaft; a release wire disposed within the lumen of the elongate shaft, wherein the release wire releasably attaches the medical device to the distal end of the elongate shaft; and an introducer sheath slidably disposed over the elongate shaft, wherein the introducer sheath is configured to disengage the proximal portion of the elongate shaft from the distal portion of the elongate shaft.

A system for implanting a prosthesis includes a control lumen and a nose cone affixed at a distal end of the control lumen. At least one supporting wire is affixed at one end, is substantially parallel to a major axis of the control lumen and is free at an opposite end, wherein the free end of at least one of the supporting wires is arcuate.

A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.

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.
