Abstract

Equipment with an incorporated cardiac radio-frequency receiver (CPR) for temporary heart stimulation from the outside in case of open-heart operation, suitable to be left insitu to provide permanent stimulation if subsequently necessary. The equipment is formed of an electrode with epi-cardial stimulation tip, and a quick jack-type connection emerging from said cardiac radio-frequency receiver and suitable to rapidly and easily connect a permanent pacemaker.

Claims

1. Apparatus for temporary heart stimulation during open-heart surgery by means of an external pacemaker transmitting radio frequency signals, and adapted to be left in situ to provide permanent stimulation if subsequently needed, comprising:

an electrode having an epi-cardial stimulation tip on one end;

a cardiac radio-frequency receiver capable of receiving radio-frequency stimulation signals clamped on said electrode; and

connecting means, on an end opposite the epi-cardial stimulation tip, emerging from the radio-frequency receiver for easy and rapid connection of said electrode to a permanent pacemaker, the parts being arranged so that, at any time after the operation, said apparatus allows the supply of either an emergency radio-frequency stimulation or a permanent stimulation without the need for a new heart operation.

2. Apparatus for temporary heart stimulation during open-heart surgery by means of an external pacemaker transmitting radio frequency signals, and adapted to be left in situ to provide permanent stimulation if subsequently needed, comprising an electrode having an epi-cardial stimulation tip for stimulation of the heart;

a cardiac radio-frequency receiver capable of receiving radio-frequency stimulation signals clamped on said electrode; and

a connecting device for the easy and rapid connection of said electrode to a permanent pacemaker comprising a quick jack-type connection directly emerging from said radio-frequency receiver, the parts being arranged so that, at any time after the operation, said apparatus allows the supply of either an emergency radio-frequency stimulation or a permanent stimulation without the need for a new heart operation.

3. Apparatus for temporary heart stimulation during open-heart surgery by means of an external pacemaker transmitting radio frequency signals, and adapted to be left in situ to provide permanent stimulation if subsequently needed, comprising an electrode having an epi-cardial stimulation tip for stimulation of the heart;

a cardiac radio-frequency receiver capable of receiving radio-frequency stimulation signals clamped on an intermediate portion of said electrode; and

a connecting device for the easy and rapid connection of said electrode to a permanent pacemaker comprising an insulated free length of said electrode on the end opposite the epi-cardial stimulation tip emerging from said radio-frequency receiver, the parts being arranged so that, at any time after the operation, said apparatus allows the supply of either an emergency radio-frequency stimulation or a permanent stimulation without the need for a new heart operation.

4. The apparatus of claim 3 wherein the epi-cardial stimulation tip and the electrode between the stimulation tip and radio-frequency receiver are bipolar, and further including a base of bio-compatible material on which is positioned the bipolar epi-cardial stimulation tip, said base adapted to attach the stimulation tip to the heart.

5. The apparatus of claim 3 wherein the epi-cardial stimulation tip and the electrode between the epi-cardial stimulation tip and radio-frequency receiver are unipolar.
