Claim 17:
18. A method of implanting a prosthetic implant, comprising:
advancing a prosthetic implant into a patient's vasculature with a delivery apparatus, the delivery apparatus comprising a catheter and a control lead, the catheter including a lumen extending therethrough, the control lead extending through the lumen of the catheter, the prosthetic implant comprising an implant body, a seal extending radially outwardly from the implant body, and a locking bar coupled to the implant body and releasably coupled to the control lead, the implant body including an inflow end portion, an outflow end portion, and a central longitudinal axis extending from the inflow end portion to the outflow end portion, the seal configured for contacting native vascular tissue and reducing leakage between the native vascular tissue and the implant body, the locking bar radially offset relative to the central longitudinal axis of the implant body and movable between an engaged state and a released state relative to the prosthetic implant;
positioning the prosthetic implant at a first location in the patient's vasculature;
rotating the control lead of the delivery apparatus in a first direction relative to the catheter while the locking bar is in the engaged state such that the locking bar rotates in the first direction relative to the implant body and the implant body expands radially from a first radially compressed state to a first radially expanded state and the prosthetic implant is positioned at the first location in the patient's vasculature;
rotating the control lead of the delivery apparatus in a second direction relative to the catheter while the locking bar is in the engaged state, such that the locking bar rotates in the second direction relative to the implant body and the implant body compresses radially from the first radially expanded state to a second radially compressed state, the second radially compressed state being larger than the first radially compressed state;
moving the prosthetic implant from the first location in the patient's vasculature to a second location in the patient's vasculature, the second location being different than the first location;
rotating the control lead of the delivery apparatus in the first direction relative to the catheter such that the locking bar rotates in the first direction relative to the implant body and the implant body expands radially from the second radially compressed state to a final radially expanded state and the prosthetic implant is positioned at the second location in the patient's vasculature;
releasing the prosthetic implant from the delivery apparatus; and
retrieving the delivery apparatus from the patient's vasculature.
