Abstract: A stent delivery catheter assembly for delivering and implanting a self-expanding stent in a body lumen includes a handle assembly for one handed use. The handle assembly has a mode selection for advancing, reversing and locking the stent delivery components. Rotation of a thumbwheel allows the physician to deploy and implant the self-expanding stent in the body lumen with control and precision by simultaneously pulling a sheath proximally and pushing a pusher member distally.

Abstract: Catheter including a pressure chamber defined by proximal and distal seals and inner and outer tubular members. An actuator member, moveable between first and second positions, is disposed within the pressure chamber. Fluid introduced into the pressure chamber applies a force on the actuator member to move the actuator member toward the second position. A lock mechanism, disposed between inner and outer tubular members, includes a latch having an engaged condition preventing movement of the outer tubular member relative the inner member and a disengaged condition allowing movement the outer member. The latch is shifted to the disengaged condition when the actuator member is moved to the second position. With the actuator member in the second position and the latch in the disengaged condition, fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to urge the outer tubular member proximally.

Abstract: A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can be configured to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.

Abstract: Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.

Abstract: A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can include a planet carrier, at least one planet gear operatively coupled to the planet carrier, a sun gear shaft operatively engaged with the planet gear, a ring gear operatively engaged with the planet gear, a first clutch driver, and a second clutch driver. The actuation assembly can be configured to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.
