摘要： 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.

摘要： A contact-free, optical measurement system for determining the precision with which an article rotates. A reflective surface is secured to a rotating surface and a light source, such as a laser, is disposed thereabove. A target is likewise secured in association with the light source to receive the reflected light from the spinning surface. In this manner, any dynamic angular misalignment, or wobble, in the spinning surface will be manifested in movement of the reflected light upon the target. The degree of wobble of the spinning surface may then be readily ascertained.
