Abstract
An apparatus for delivering an implant within a lumen or passageway is provided. The apparatus comprises a flexible, hollow outer member having an elongated section that is inserted into and navigated through the lumen of passageway. The implant is mounted within the distal end of the elongated section. An elongated fluid chamber is defined within the outer member between two valves or seals. The valves or seals permit fluid flow in a pre-determined direction during loading of fluid into the chamber, but prevent fluid to exit the chamber during deployment of the implant. A shaft is in contact with the proximal end of the fluid column. During deployment, the shaft is held in a fixed position and the outer member actuated in a proximal direction. The implant exerts compressive forces on the outer member as it is actuated proximally. These forces are transmitted to the fluid column which resists buckling.
