Claim Text:
1. A prosthesis delivery system comprising: a handle assembly including a rotatable control knob; an intermediate shaft extending from the handle assembly and having an interior lumen, the intermediate shaft having a prosthesis retaining element connected to a distal end thereof; an introducer shaft having an interior lumen and a tapered introducer tip attached at a distal end thereof, wherein a proximal end of the introducer shaft is connected to a hub secured to the intermediate shaft and configured to slide in a proximal and distal direction along the intermediate shaft; an inner shaft extending from the handle assembly and configured to be moved in a proximal direction by rotating the control knob in a first direction and to be advanced in a distal direction by rotating the control knob in a second direction that is opposite of the first direction; and a capsule including a proximal end, a distal end and a capsule tip, wherein the distal end of the capsule is connected to a distal end of the inner shaft, the proximal end of the capsule is configured to have an interference fit with the prosthesis retaining element of the intermediate shaft in a deployment stage and to receive the tapered introducer tip in each of a delivery stage and a retraction stage, and the capsule is configured to contain a prosthesis device, and wherein when the control knob is rotated in the second direction the inner shaft and the capsule advance together in the distal direction relative to the prosthesis device until the proximal end of the capsule contacts the prosthesis retaining element and thereafter further distal advancement is prevented.
