Abstract: A stent-graft comprises: a graft defining an elongate lumen having a longitudinal axis; an external stent having a plurality of struts and apices between the struts, the apices including proximal apices and distal apices; a set of proximal sutured knots, the proximal sutured knots securing the proximal apices of the stent to the graft; a set of distal sutured knots, the distal sutured knots securing the distal apices of the stent to the graft; and a plurality of intermediate sutured knots, formed along a continuous suture, the continuous suture including a plurality of bridging portions, the bridging portions bridging between neighbouring struts of the stent, the intermediate sutured knots securing struts of the stent to the graft.

Abstract: Disclosed herein is an anchor for use with a medical device. The anchor includes a coil, a barb, and a turn connecting the coil to the barb. The anchor may be made of a shape memory material. The coil may have a first handedness, and the turn may have a second handedness opposite the first handedness. The anchor may be attached to the medical device by a friction fit, in some cases without being attached by welding, soldering, adhesive, or crimping.

Abstract: A stent delivery system includes a cannula with a proximal end separated from a distal carrier segment by an unbroken inner surface and an unbroken outer surface. The distal carrier segment is attached to a tip, and the proximal end of the cannula is attached to a hub. A pusher is co-axially mounted about the cannula and has a proximal end attached to the hub. A retractable sheath is co-axially mounted about the cannula and the pusher, and is movable between a first position covering the distal carrier segment and a second position uncovering the distal carrier segment. A self expanding stent is mounted about the distal carrier segment. The hub includes exactly one flushing port in fluid communication with a lumen of the cannula and annular passage between the cannula and the pusher.

Abstract: A controlled expansion stent graft delivery system has an adjustment configuration in which a retractable sheath is at a retracted position out of contact with a stent graft, but expansion of the stent graft is controlled by a control tether, which has a middle segment wrapped around a fabric tube of the stent graft. The stent graft changes diameter responsive to a tension level in the control tether. At least one of an orientation and a position of the stent graft may be adjusted during controlled expansion via the control tether. After proper placement of the stent graft, a tip clamp assembly can be actuated to unclamp and release the control tether.

Abstract: The stent delivery device includes a pistol shaped handle with a barrel portion extending atop a grip portion. A trigger actuator is pivotably mounted to the pistol shaped handle and defines an angle with respect to the grip portion. A carrier is slidably mounted to the barrel portion of the pistol shaped handle. A mechanical linkage, which includes a roller clutch, interconnects the trigger actuator to the carrier. The angle is reduced responsive to pivoting the trigger actuator in an actuation direction toward the grip portion, and the angle is increased responsive to pivoting the trigger actuator in a re-set direction. The roller clutch is oriented in the mechanical linkage to rotate responsive to the trigger pivoting in the re-set direction, but the roller clutch is held against rotation responsive to pivoting the trigger in the actuation direction.

Abstract: An occlusion device for occluding a body vessel and methods of using the device are disclosed.

Abstract: A pre-loaded stent graft delivery device having a guide wire catheter and a handle including a multi-port manifold with access ports, where an access sheath extends from each access port. A sheath is disposed coaxially around the guide wire catheter and includes two splits that enable the retraction of the sheath while the access sheaths are disposed within the respective access port of the manifold.

Abstract: A system for delivery and deployment of an occluder includes a handle, an actuating mechanism with a motion amplifier and a sheath positioning mechanism within the handle. A driveshaft of the actuating mechanism extends through the handle, the sheath positioning mechanism, and an attached sheath so as to couple with an occluder deployed via the driveshaft within a body lumen in a patient.
