Abstract: A handle assembly for a prosthesis delivery device is disclosed. The handle assembly comprises a stationary main handle having a proximal end and a distal end and an outer surface extending therebetween. A first helical groove is formed in at least a portion of the outer surface of the main handle and a first trigger wire actuation mechanism disposed about the main handle and rotatably moveable relative to the main handle. A first trigger wire is operatively connected to the first trigger wire actuation mechanism, the first trigger wire having a prosthesis capture condition and a prosthesis release condition. Movement of the first trigger wire actuation mechanism causes movement of the first trigger wire thereby moving the first trigger wire from the prosthesis capture condition to the prosthesis release condition. Additional trigger wire actuation mechanisms operatively connected to one or more additional trigger wires may also be disposed about the main handle.

Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, which define an elongated tube with a lumen. The elongated tube has first and second sections, the first section having a substantially constant first diameter, the second section having a substantially constant second diameter that is larger than the first diameter. The elongated tube also has a transition section between the first and second sections, the transition section having a concave curvature extending proximally from the first section and a convex curvature extending proximally from the concave curvature to the second portion. A proximal end of the second section has a plurality of rounded ends formed by the plurality of intersecting elongated members. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second section.

Abstract: A modular handle assembly for a prosthesis delivery device is disclosed. The modular handle assembly has a stationary main handle and a first handle that extends proximally from the main handle and is rotationally moveable relative to the main handle. A second handle extends distally from the main handle and is rotationally moveable relative to the main handle. The main handle has a first rotational interface and a second rotational interface that are configured to engage with the first handle and the second handle, respectively.

Abstract: A prosthesis delivery device and method are described herein. An elongate sheath extends about a longitudinal axis, and a hub is coupled to the sheath. A handle is distal to the hub, and a connector assembly is coupled to a proximal end of the handle. The connector assembly is removably coupled to the hub, and the connector assembly includes a longitudinal passageway defined therein in communication with the longitudinal hub lumen. In one aspect, the connector assembly includes a plurality of jaw elements, and an actuating ring operable to move the jaw elements between the attachment configuration where the jaw elements are coupled to the hub, and the detachment configuration where the jaw elements are radially displaced and decoupled from the hub to remove a component from the sheath lumen.

Abstract: The present embodiments provide a prosthesis deployment system, and method of deployment of a prosthesis using the same, having a positioning member at least partially disposed within a tubular segment of a tip assembly. The positioning member is movable between nondeployed and deployed configurations. In the nondeployed configuration the positioning member can permit the tip assembly to move relative to the enlarged body assembly. When an enlarged body is at a position farther away from a tip body, which may be at the edge of the tubular segment, the positioning member can move or flare to its deployed configuration to inhibit the enlarged body from moving relatively closer to the tip assembly. Axial force applied to the tip assembly during withdrawal of the tip assembly can be transmitted via the positioning member to the enlarged body assembly to facilitate its withdrawal from the body.

Abstract: The disclosure is directed to a pre-loaded stent graft delivery device. The pre-loaded stent graft delivery device includes a guide wire catheter having a guide wire lumen therethrough; and a handle assembly disposed at a distal end of the guide wire catheter. The handle assembly includes a proximal handle, a rotational handle, a slot, and a sheath follower. The proximal handle, including a manifold including at least one side port, is disposed at a proximal end of the handle assembly. The slot is disposed inside the rotational handle, and is fixed and remains stationary relative to the proximal handle. The sheath follower is disposed slidably in the slot and fixed to a distal portion of a sheath. The rotational handle includes an internal thread mechanically coupled with the sheath follower, so that, when the rotational handle rotates toward a first rotational direction, the sheath is pulled to move distally.

Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, the plurality of cells defining an elongated tube with a lumen running therethrough. The elongated tube has first, second, and third sections, the first section having a substantially first diameter and the third section having a substantially constant second diameter that is larger than the substantially constant first diameter of the first section, wherein the diameter of the second section transitions from the first diameter to the second diameter. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second and third sections. In the second section, the plurality of intersecting elongated members includes a plurality of pairs of elongated members, wherein each pair of elongated members includes two adjacent elongated members twisted axially around each other.

Abstract: A handle assembly for a prosthesis delivery device is disclosed. The handle assembly comprises a stationary main handle having a proximal end and a distal end and an outer surface extending therebetween. A first helical groove is formed in at least a portion of the outer surface of the main handle and a first trigger wire actuation mechanism disposed about the main handle and rotatably moveable relative to the main handle. A first trigger wire is operatively connected to the first trigger wire actuation mechanism, the first trigger wire having a prosthesis capture condition and a prosthesis release condition. Movement of the first trigger wire actuation mechanism causes movement of the first trigger wire thereby moving the first trigger wire from the prosthesis capture condition to the prosthesis release condition. Additional trigger wire actuation mechanisms operatively connected to one or more additional trigger wires may also be disposed about the main handle.
