A connector assembly for use in connecting an intracardiac catheter having a bare end connector to a patient monitor. The assembly includes an adapter, a terminal block and a cable. The adapter has an elongate insulating conductive member defined by an intermediate portion and opposite ends. A first connector is electrically connected to and is mounted at one end of the conductive member and a second connector is disposed at the other end of the conductive member. The first connector includes a first terminal connected to the conductive member for electrically engaging a bare pin connector in a surrounding relation and a tubular insulating cover extending from the one end of the adapter for telescopingly receiving the first terminal and the bare pin connector. The second connector includes a second terminal connected to the conductive member and extending from the other end of the conductive member and an insulating skirt mounted on the second connector in surrounding relation to the second terminal. The terminal block has a plurality of sockets, each socket comprising a recess complementary to the insulating skirt for receiving and securing the skirt therein, and a plurality of third terminals one of which is disposed in each socket and each being electrically engageable with the second terminal. The cable has a plurality of individual conductors each connected at one end respectively to one of said third terminals and a plug at its other end for connection to a patient monitor.

Connector for catheter electrode

An ablation system includes a catheter adapted to be inserted into the heart of a patient. The catheter has a distal end and a plurality of electrodes disposed adjacent the distal end. One of the electrodes being an ablation electrode. An ablation RF energy source connected to the ablation electrode, a patient interface is connected to at least some of the electrodes for acquiring intracardiac ECG signals and a stimulator is connected to the catheter for providing pacing signals thereto. A phase balanced all pass filter is connected between the catheter and the patient interface for suppressing the interference to the intracardiac ECG signals by the RF ablation energy signal.

Cardiac ablation system

An implantable, passive bio-sensor (10) for monitoring internal physiological conditions of a patient is disclosed. The bio-sensor (10) includes at least one sensor or transducer (12) for monitoring a physiological condition of the patient and a passive transponder (14) that receives sensor signals from the sensor or sensors (12), digitizes the sensor signals, and transmits the digitized signals out of the patient's body when subjected to an externally generated interrogation signal. In one embodiment, the bio-sensor (100) is incorporated into the sidewall of a shunt (102) used for treating hydrocephalus for non-invasively monitoring the operation of the shunt (102).
