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: A method and an assembly for securing a crimped medical device over a deflated balloon of a balloon catheter is provided. The medical device is positioned in its expanded state over the deflated balloon of the balloon catheter, and is then crimped over the deflated balloon. First and second eyelets of first and second strings, respectively, are then threaded through first and second rings, respectively, that are provided on the medical device. Next, a locking wire is advanced through a lumen defined between the sheath and the catheter body to exit the distal end of the sheath, and then advanced through the first and second eyelets and into the distal tip of the balloon catheter. The sheath is then advanced over the crimped medical device to the distal tip to completely cover the crimped medical device.
