Abstract: An electronic patch, for stimulating tissue healing at a target site, is flexible enough to generally conform to a body surface adjacent to the target site, and includes a battery or an arrangement of multiple batteries less than 5 mm thick; a capacitor connected durectly with a coil in series; and pulse generating circuitry, powered by the battery or batteries. The circuitry repeatedly changes the voltage across the capacitor and coil, to produce pulses of current in the coil. The current produces a pulsed electromagnetic field at the target site for stimulating tissue healing, most of the electromagnetic field energy of each pulse being converted into electrostatic energy of the capacitor at the end of the pulse and back into electromagnetic field energy of the next pulse.

Abstract: An anchor for attaching injured soft tissue to a bone and generating a therapeutic electromagnetic field at least in a part of the soft tissue when the soft tissue is sutured to the anchor, the anchor comprising: a) an affixing portion configured for affixing the anchor to the bone; b) a coil that generates the electromagnetic field when a current runs through it; c) an electronics module that controls the current in the coil; and d) an electric power source that provides electric power to the electronics module and the coil.
