1. A medical assembly comprising:
an implant delivery device comprising
a handle, and
a catheter extending from the handle, the catheter having a distal end section comprising one or more motors configured to be inserted into a vessel of a patient; and
an implantable medical device coupled to the distal end section of the catheter, wherein the one or more motors are configured to produce radial expansion of the implantable medical device from a radially compressed state to a radially expanded state inside the patient;
wherein the distal end section of the catheter comprises one or more radially adjustable structures and the one or more motors are configured to radially expand the one or more radially adjustable structures to radially expand the implantable medical device from the radially compressed state to the radially expanded state inside the patient;
wherein the catheter comprises an elongated catheter body and the one or more radially adjustable structures are disposed on the catheter body; and
wherein the one or more radially adjustable structures are located within one or more trenches formed on an outer surface of the catheter body.
