摘要： A needle injection catheter includes a delivery tube that slidably surrounds a hypotube that has at least three hollow needle portions connected to and extending outwardly at its distal end. The needle portions are formed of resilient material and curve outwardly from the delivery tube. The ends of the needle portions are shaped to penetrate tissue when the hypotube is urged out of the delivery tube. A first sensor is located adjacent the distal end of the delivery tube and a second sensor is located adjacent the end of the needle portion. The sensors are electrically connected to first and second notification devices located adjacent a first end of the delivery tube. Radiopaque markers are affixed to the delivery tube to locate the tip using an enhanced imaging system. The markers are sized, shaped, positioned and of different densities to locate the tip both axially and radially within body structures.

摘要： 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.
