A stent delivery system includes an elongate shaft including a proximal portion, a distal portion, at least one lumen extending at least partially therethrough, and a stent receiving portion on the distal portion of the elongate shaft. A stent is positioned on the stent receiving portion of the elongate shaft. A proximal constraining arrangement is engaged with a proximal end of the stent. A distal constraining arrangement is engaged with a distal end of the stent. A release wire is disposed through the elongate shaft and releasably engaged with portion of the proximal constraining arrangement and the distal constraining arrangement member. A handle assembly comprising a shuttle and a spring arrangement is positioned therein. A first brake assembly is disposed within the handle assembly and a second brake assembly is disposed within the handle assembly proximal to the first brake assembly.

A prosthesis delivery device and method of using the same is described. The delivery device comprises a rotatable inner cannula extending from a proximal end to a distal end with a prosthesis releasably coupled to the proximal end. A delivery handle assembly is disposed at the distal end of the delivery device. The handle comprises a first handle disposed about the inner cannula, a rotary dial rotatably disposed about a distal end of the first handle and a second handle disposed about at least a portion of the distal end of the first handle. The second handle is longitudinally moveable relative to the first handle between a first position wherein the sheath is coaxially disposed about the prosthesis and rotation of the rotary dial is prevented, and a second position wherein the sheath is retracted distally to expose at least a portion of the prosthesis and rotation of the dial is permitted.

An elongate delivery shaft assembly (30) includes an outer covering shaft (38) and an inner support shaft (40). When the delivery shaft assembly (30) is unconstrained and a stent-graft (20) is removably constrained in a radially-compressed delivery state along a distal end portion (34) of the delivery shaft assembly (30), radially between the outer covering shaft (38) and the inner support shaft (40): (a) the delivery shaft assembly (30) is shaped so as to define a self-orienting portion (50), which (i) is shaped so as to define at least proximal and distal curved portions (52A, 52B), the proximal curved portion (52A) disposed more proximal than the distal curved portion (52B), and (ii) at least one point of inflection (53) on a central longitudinal axis (36) of the delivery shaft assembly (30) longitudinally between the proximal and the distal curved portions (52A, 52B), and (b) respective smallest radii of curvature of the proximal and the distal curved portions (52A, 52B), measured at the central longitudinal axis (36), are each between 2.5 and 12 cm.

A system for positioning an intraluminal device includes a catheter having an elongated catheter body having a distal portion configured for delivering the intraluminal device and a catheter tube having a wire spanning a length thereof. The system also includes a handle attached to the elongated catheter body and having at least one steering mechanism configured for pushing the catheter tube in a distal direction thereby steering the distal portion of the elongated catheter body and positioning the intraluminal device for delivery.

Devices for delivering and deploying an endoluminal prosthesis are disclosed and comprise a delivery catheter, an endoluminal prosthesis disposed at a distal end portion of the delivery catheter, and a wire. The prosthesis comprises a tubular graft having at least one fenestration. The wire extends distally from a first wire end through an axial lumen of the delivery catheter and the prosthesis, and through the fenestration in the graft. The wire extends proximally through a lumen of the prosthesis and through an axial lumen of the delivery catheter towards a second wire end. Additional devices, systems, and methods are disclosed.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include an implantable medical device and a constraining line conduit arranged around a circumference of the implantable medical device. The apparatuses, systems, and methods may also include a constraining line arranged through the constraining line conduit.

Embolic implants delivery systems and methods of manufacture and delivery are disclosed. The devices can be used for aneurysm and/or fistula treatment. The designs offer low profile compressibility for delivery to neurovasculature, while maintaining advantageous delivery and implant detachment control features.

A prosthesis introducer system may include an introducer. A trigger wire release mechanism and a restraining member may be positioned near the distal end of the introducer. The system may include first and second trigger wires, each including a proximal portion releasably coupleable to a portion of a prosthesis and a distal portion coupled to the trigger wire release mechanism. The second trigger wire may be engaged by the restraining member. Each of the first and second trigger wires may include a taut portion. The second trigger wire may include a slack portion extending distally from the taut portion and positioned distal of the restraining member. Upon actuation of the trigger wire release mechanism, the first trigger wire may be releasable from the prosthesis and the second trigger wire may be releasable subsequent to the release of the first trigger wire.
