Abstract
A method for pre-loading an implant delivery apparatus and for delivering an implant is provided. An implant is mounted within the distal end of an elongated section of a delivery apparatus. After the implant is mounted within the elongated section, fluid is drawn into a chamber within the delivery apparatus that is proximal to the implant. This is accomplished by drawing fluid, such as a biocompatible liquid, into the chamber by applying pressure to a port. The fluid is trapped inside the chamber forming a liquid column. The elongated section is advanced through a lumen or passageway delivering the implant to a desired location. A shaft, which is in communication with the fluid column, is held stationary and the elongated section retracted deploying the implant. As the elongated section is retracted, the implant exerts forces upon the elongated section that are transmitted to the fluid column which resists buckling.
