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.

A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.

A stent graft delivery system. The system includes a stent graft cover having a central longitudinal axis. The stent graft cover houses a first guidewire lumen extending along a first guidewire lumen axis and configured to track along a first guidewire. The first guidewire lumen axis is offset the central longitudinal axis. The stent graft delivery system further includes a tapered tip extending distally from the stent graft cover and defining an offset through-channel extending within the tapered tip along a tapered tip offset axis and configured to track along the first guidewire. The first guidewire lumen axis and the tapered tip offset axis extend along a common axis.

An implantable device delivery system is disclosed. The delivery system includes a constraining member situated between an interior layer and an exterior layer of a cover. The interior layer of the cover is disposed about an implantable medical device, and the exterior layer of the cover extends over a portion of the interior layer. The cover is generally tapered to minimize deployment forces. The constraining member is disposed about a portion of the interior layer and operates to constrain the implantable device to a delivery configuration. The cover and the constraining member are generally configured to be removed concurrently during deployment of the implantable device.

Methods for delivering a pulmonary or mitral valve prosthesis using a transcatheter approach are provided. The implantation devices can utilize movable claspers for both positioning and anchoring the valve prostheses within the native cardiac valve, minimizing the extent of imaging necessary.

A delivery system for delivering a stent-valve may include an inner shaft including a distal tip, a stent-valve crimped onto the inner shaft, a distal sheath disposed over at least a lower portion of the stent-valve, and a proximal sheath disposed over at least an upper portion of the stent-valve. The distal sheath has a proximal free end with an angled proximal edge defining a short side and a long side of the distal sheath. The proximal sheath is actuatable independently from the distal sheath, and moveable proximally to release the upper portion of the stent-valve. The distal sheath is moveable distally to release the lower portion of the stent-valve. The angled proximal edge releases a first side of the lower portion of the stent-valve before an opposite second side.

A delivery system for delivering an endovascular graft within a blood vessel. The delivery system includes a tip assembly including a tip and a sleeve having a proximal end. The delivery system includes a tip capture mechanism. The tip assembly is configured to move axially relative to the tip capture mechanism and between a delivery position and a release position. The tip capture mechanism includes a landing zone. The delivery system includes a travel limiter configured to align the proximal end with the landing zone when the tip assembly is in the release position to facilitate removal of the delivery system from the blood vessel.

A stent graft delivery system and method of assembling the same is disclosed. The stent graft delivery system includes a stent graft cover configured to maintain a stent graft in a constricted configuration, and is configured to slide relative to the stent graft to enable the stent graft to expand radially outwardly. The stent graft cover extends along a first central axis. A tapered tip defining an opening therethrough is configured to track along a guidewire. The opening extends along a second central axis that is offset from the first central axis. This provides a delivery system with an opening in a leading edge that is not center relative to the outer stent graft cover.

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.

An implantable device delivery system is disclosed. The delivery system includes a constraining member situated between an interior layer and an exterior layer of a cover. The interior layer of the cover is disposed about an implantable medical device, and the exterior layer of the cover extends over a portion of the interior layer. The cover is generally tapered to minimize deployment forces. The constraining member is disposed about a portion of the interior layer and operates to constrain the implantable device to a delivery configuration. The cover and the constraining member are generally configured to be removed concurrently during deployment of the implantable device.
