Abstract: The present invention provides a valvuloplasty catheter which has a scoring element at its distal part to score stenotic, calcified heart valves in radial direction and to make the single valve flaps/leaflets work again. In addition to this, the device could comprise an attached balloon to post-dilate the valve after the scoring procedure. To reduce a future recalcification, the scoring element and/or the balloon have a pharmacologic coating on their outer surface.

Abstract: The needle injection catheter includes a delivery tube and at least one hypotube that fits slidably within the delivery tube. The hypotube has at least three hollow needle portions extending outwardly at its distal end. The needle portions curve outwardly and have ends shaped to penetrate tissue. At least one reference electrode is located on the delivery tube, spaced from the second end. At least one proximal electrode is located adjacent and spaced from the end of the needle portion. The proximal electrode is electrically connected to a first notification device. A microcircuit is electrically connected to the proximal electrode, the reference electrode and to a power supply. A distal electrode is located adjacent the end of the needle portion and electrically connected to the microcircuit. A tip electrode is located adjacent the second end of the delivery tube and electrically connected to a second notification device and the microcircuit.
