Micro-motor actuated therapeutic device
First Claim
1. A system for performing a vascular therapy comprising:
- a catheter having a distal end and an axis;
a micromotor attached to the catheter;
a power source coupled to the catheter but distant from the distal end of the catheter; and
a therapeutic device actuated by the micromotor and connected to the catheter adjacent the distal end of the catheter and actuated by the micromotor.

Abstract
An in vivo source of mechanical energy is provided in close proximity to its load. In the disclosed embodiments, the mechanical energy source is a miniaturized motor (“micromotor”) and the load is a miniaturized perfusion pump located at the distal end of a transluminal catheter. The motor is powerful enough to provide the electrical energy needed by the perfusion pump to fluid, and yet small enough to fit inside a body vessel. A position sensor may be provided for automatically controlling the motor'"'"'s driving current so that it is corresponds to the applied load. An embodiment of the perfusion pump is also provided in which an external energy source is used. Another embodiment is provided wherein a balloon/pump/miniaturized-motor configuration is provided on a distal end of a catheter.
