Abstract: A muscle therapy device that can be used for self-myofascial release is disclosed. In some embodiments, the device includes one or more ellipsoids configured coaxially around a rigid axle, the axle including circular wheels fixedly attached at opposite ends. In these embodiments, the one or more ellipsoids extend radially from the axle and form contact surfaces at an outer edge. In various embodiments, the contact surfaces of the device include raised bands configured concentrically with the axle or the contact surface may comprise one, two or more bands that are spirally wound around the axle. The raised bands may include rounded surfaces and define a series of channels there between. In one embodiment, the device includes at least two ellipsoids which are configured coaxially with the axle and form a concave recess there between. In this embodiment, the concave recess can essentially form a shape that approximates an elliptical hyperboloid.
