A stent graft for treating an arterial aneurysm includes a ligature traversing at least a portion of struts of stents, the ligature having ends that, when linked, at least partially constrict a radial dimension of the stents. The ends of the ligature can be linked by a wire in a stent graft delivery system that threads anchor loops longitudinally spanning ends of the ligature to maintain the stent in a radially constricted position during delivery to the aneurysm. The stent graft can be implanted at the aneurysm by retracting the wire from the linked ends of the ligature and from the anchor loops, thereby releasing the associated stent from the radially constricted position.

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for placing the muscularis layers of first and second body lumens in contact to establish a long term or permanent open flow or access passage therebetween.

The disclosure relates to transcatheter stented prosthesis delivery devices including transition elements that route, constrain, support and reduce damage to tension member wear as tension in the tension members is varied to adjust the compression of a stented prosthesis loaded onto the delivery device. Various disclosed tension elements include inserts, edge treatments and guides proximate a distal portion of the delivery device upon which the stented prosthesis is loaded. In some embodiments, the transition feature is positioned proximate a location where at least one tension member transitions from a first orientation that is not parallel to the distal portion to a second orientation that is generally parallel to the distal portion. Further embodiments disclose configurations and methods of selectively locking and unlocking a longitudinal and/or rotational position of the stent frame with respect to the distal portion of the delivery device.

A removable constraining device, systems, and methods for constraining and delivering an expandable member is disclosed. The removable constraining device includes a plurality of strands interlocking to form a cover body having a length, the plurality of strands in the form of a warp knit, and the plurality of strands including at least a first set of strands and a second set of strands. The removable constraining device also includes a first release zone defined by the first set of strands of the cover body along the length of the cover body and a second release zone defined by the seconds set of strands of the cover body, the second release zone being coextensive with the first release zone along at least a portion of the length of the cover body. The removable constraining device may be released at release zones by substantially simultaneously tensioning deployment lines.

A braided member can include a first set of yarns extending in a first direction, a second set of yarns extending in a second direction and intertwined with the first set of yarns, and a set of axial yarns extending along a longitudinal axis of the braided member and disposed between the first set of yarns and the second set of yarns. The braided member can include a tubular braid.

A suture rigging assembly for use with a prosthetic heart valve delivery device includes a coupling ring having a plurality of apertures, and at least one tether coupled to the apertures of the coupling ring and extending distally therefrom. Each tether is formed by two lengths of suture thread, the lengths of suture thread joined together at a position spaced from the coupling ring, and a second joining of the lengths of suture thread forming an attachment loop at the distal end of the tether. The first connection in the tethers collectively define the shortest and longest lengths of each of the tethers, and the attachment loops provide a mechanism to releasably attach the tethers to a prosthetic heart valve. Optionally, knots can be used to join the tethers and one or more tethers may include a radiopaque marker secured thereon between two knots.

An intravascular device delivery system includes a distal end cap to connect an elongated member of the intravascular device delivery system to an intravascular device. The distal end cap includes at least one connection member radially movable relative to the distal end cap that is configured to engage with a complimentary recess in the intravascular device.

A stent delivery system includes a core member and an expandable member coupled to the core member distal segment. A stent extends along the core member distal segment such that an inner surface of the stent is positioned over the expandable member. The stent has a primary heat-set configuration where the stent is radially expanded, and a secondary heat-set configuration where the stent is radially compressed. The expandable member is adapted to radially expand at least a portion of the stent from a radially compressed configuration toward a radially expanded configuration.

A modular handle assembly comprises a stationary main handle having proximal and distal ends. A first handle extends proximally from the main handle and is rotationally moveable relative to the main handle, the first handle having proximal and distal ends, wherein a rotational interface is located at the distal end. A second handle extends distally from the main handle and is rotationally moveable relative to the main handle, the second handle having proximal and distal ends, wherein a rotational interface is located at the proximal end. The proximal end of the main handle comprises a first rotational interface that is configured to engage with a rotational interface at the distal end of the first handle and wherein the distal end of the main handle comprises a second rotational interface that is configured to engage with the rotational interface at the proximal end of the second handle.

Stent-valves (e.g., single-stent-valves and double-stent-valves), associated methods and systems for their delivery via minimally-invasive surgery, and guide-wire compatible closure devices for sealing access orifices are provided.
