摘要： An apparatus and method for catheter-based sensing and injection at a target site within a patient's body. An injection catheter is equipped with electrodes at its distal end which contact the surface of a target site, such as an AV node of the heart. Electrical signals detected at the target site by the electrodes are fed via leads to the proximal end of the catheter, where they are received by a monitor, such as an EKG monitor. If the electrical signals satisfy predetermined criteria, a needle within the catheter is extended into the target site, and a therapeutic agent is injected into the target site.

摘要： An apparatus for the injection of therapeutic and other agents at a target site within a patient's body. A catheter including a first elongated shaft having a distal end and a proximal end and a lumen extending therebetween. The catheter also including a second elongated shaft slidingly disposed in the first elongated shaft, the second elongated shaft having a distal end and a proximal and a lumen extending therebetween. The catheter further including a third elongated shaft disposed in and attached to the second elongate shaft, the third elongated shaft to move in a one-to-one relationship with the first elongated shaft and the second elongated shaft to maintain a predetermined needle deployment length as each are subjected to various bend configurations.
