Stent delivery device including an inner member having a distal tip, a stent support member, and a stent disposed over a stent receiving region of the stent support member. An elongated outer sheath is slidably disposed over the inner member and the stent. The stent delivery device includes a distal junction removably coupling the distal end of the outer sheath to the distal tip, where the distal junction is actuatable to decouple the outer sheath from the distal tip. The stent delivery device includes a proximal junction removably coupling a distal portion of the outer sheath to a proximal portion of the outer sheath, where the proximal junction is actuatable to decouple the distal portion of the outer sheath from the proximal portion of the outer sheath. The distal and proximal junctions may be separately actuatable by rotating the inner member relative to the proximal portion of the outer sheath.

An apparatus and method of deploying a stent graft having a proximal anchor stent ring includes restraining proximal apexes of the proximal anchor stent ring between a spindle body of a spindle and a control release sleeve of a tapered tip. The control release sleeve is advanced relative to the spindle to release a first proximal apex through an opening in the control release sleeve while the remaining proximal apexes remain restrained by the control release sleeve. The control release sleeve is further advanced relative to the spindle to release the remaining proximal apexes from the control release sleeve. In another example, a stent capture fitting has variable length stent capture fitting arms. As the stent capture fitting is retracted, the proximal apexes of the proximal anchor stent ring are sequentially exposed from and released by the variable length stent capture fitting arms. By using the control release sleeve or the stent capture fitting, controlled sequential release of the proximal apexes is achieved.

An implant delivery system including a catheter having a delivery lumen; a pusher member slidably disposed in the catheter delivery lumen; a retaining member coupled to a distal end portion of the pusher member, the retaining member configured to retain an expandable implant in a collapsed configuration on the pusher member for delivery of the implant through the catheter delivery lumen; and an expandable actuator coupled to the distal end portion of the pusher member and operatively associated with the retaining member, wherein expansion of the actuator causes the retaining member to disengage from an implant carried on the pusher member, to thereby allow the implant to expand from the collapsed configuration.

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

The present disclosure provides a variety of prostheses, delivery systems and techniques to facilitate closure of transvascular or transcameral access ports. Various embodiments of prostheses are provided including a plurality of radially expandable discs that can be filled with material to facilitate coagulation and to reduce or stop leakage from punctures in vessel walls.

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.
