Abstract
A replaceable catheter system provides a way to replace an implantable sensor, electrode system, and/or fluid delivery/receiving system. The replaceable catheter includes an elongated tubular catheter holder for surgical implantation in a patient. The catheter holder has an open neck at a proximal end thereof just under the patient's skin. A distal end of the catheter holder extends into a body cavity in the patient. A manually replaceable catheter is inserted through a self-sealing barrier over the open end of the catheter holder. A distal end of the replaceable catheter extends longitudinally through the catheter holder and beyond the distal end thereof to expose one or more physiological/chemical sensors, tissues stimulating electrodes, and/or a fluid delivery/receiving tube carried by or formed within the replaceable catheter. The sensors and/or electrodes are electrically connected to an electronic package including a signal coupler adjacent a signal coupler carried by the catheter holder. The signal coupler is connected to an implanted control device whereby electrical signals are transmitted to and/or from the sensor and/or electrode from the control device. The control devi…
