1. A method of in vivo motor operation for implant deployment in a patient, the method comprising:
introducing a catheter body into the patient, the catheter body comprising one or more motors, wherein an implant is mounted in a radially compressed state on the catheter body, wherein the implant has a constant outer diameter in the radially compressed state;
deploying the implant in vivo from the catheter body, the implant radially expanding during the deploying of the implant, the deploying of the implant driven by the one or more motors performing a plurality of actuation cycles while in vivo;
wherein the one or more motors comprise a plurality of motors axially spaced from each other along the catheter body; and
wherein deploying the implant comprises independently controlling the plurality of motors by actuating the plurality of motors different amounts such that the plurality of motors radially expand the implant to a radially expanded state in contact with anatomical structure surrounding the implant, the implant in the radially expanded state having a variable diameter along a length of the implant;
withdrawing the catheter body including the motors from the patient while the implant remains in the radially expanded state with the variable diameter along the length of the implant and in contact with the anatomical structure within the patient.
