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.

Catheter having hydraulic actuator and locking system

A catheter system for implanting an endoprosthesis at a treatment site in a patient's body lumen. The catheter includes an elongated shaft outer member and a stent sheath distal portion and a self-expanding stent radially restrained in a collapsed configuration within the stent sheath distal portion. A balloon catheter dimensioned for relative axial movement within the shaft outer member has an elongated shaft having an inflation lumen and a device receiving lumen. A stent stop secured to the balloon catheter is reversibly radially expandable to deploy from a collapsed to a radially expanded configuration. In the expanded configuration, the stent stop prevents longitudinal displacement of the stent. A balloon is located on a distal shaft section is releasably locked with respect to the shaft outer member and slidably disposed therein in an unlocked configuration.

Stent delivery catheter system and method of implanting a self-expanding stent with embolic protection

A catheter system and method for implanting an endoprosthesis such as a stent at a treatment site in a patient's body lumen. The catheter provides a complete system for stent delivery, dilatation, and delivery and/or recovery of an expandable device, such as an embolic protection device, adjacent to the treatment site in the body lumen.
