Neurostimulation unit for immobilizing the heart during cardiosurgical operations
First Claim
1. A device for temporarily reducing the movement of the heart during surgery, comprising:
- a neurostimulation device for stimulating nerves that slow down the heart rate, having at least one electrode device with at least one stimulation pole and a control unit being connected to the neurostimulation device having a first input device for preselecting a degree of electric immobilization of the heart and being arranged for patient specifically influencing the operation mode of the neurostimulation device as a function of the preselected degree of electric immobilization, wherein the first input device is arranged for variably preselecting the degree of electric immobilization during operation.

Abstract
The invention relates to a device for temporary reduction of heart movement during an operation, more particularly a heart operation, comprising a neurostimulation unit (20) for stimulation of the nerves (3) that slow down heart frequency, said unit including at least one electrode device (1) with at least one stimulation pole (2), wherein a control unit (19) connected to the neurostimulation device (20) is provided. Said control device has a first input device (26) for inputting a degree of immobilization and is configured to influence the operating state of the neurostimulation device (20) depending on the previously set degree of immobilization.
