Abstract
Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly with a rotatable control knob and a catheter including an introducer shaft, an intermediate shaft extending from the handle assembly, an inner shaft extending from the handle assembly, and a capsule for containing a prosthesis. The distal end of the capsule can be connected to a distal end of the inner shaft, which can be moved in a distal direction by the rotatable control knob to deploy the prosthesis. By advancing the introducer through the deployed prosthesis and retracting the capsule to mate with the introducer, a smooth profile can be created for retraction of the system through the deployed prosthesis, minimizing hang-ups and snagging.
