Abstract: Methods and apparatuses are disclosed for providing pulsed electrical treatment (including high voltage, sub-microsecond pulsed electric energy) to tissue, including cardiac tissue. The apparatus may include deployable electrodes that conform to transitional surfaces. These apparatuses may include single or multiple tiers of wire loops forming petal-like electrodes.

Abstract: A device for exercising leg muscles, ligaments, and tendons attendant to movement of a human knee following knee replacement surgery or during rehabilitation following knee injury is provided. The user lies supine on a flat surface and braces the back of his or her upper thigh against the device's leg support bar, so that the user's upper thigh is approximately perpendicular to the user's upper torso. The patient maintains this position and exercises the knee by extending and flexing his or her lower leg. Some embodiments include an elastic band that attaches to the device in a position that limits the degree of leg flexion to within a desired range. Some embodiments include an ankle strap attached to a cord, which may be used to build quadriceps strength through application of resistance, and/or for applying downward pulling force to the lower leg during passive range-of-motion exercising.
