Study of TransAeris® System for Enhanced Recovery After Surgery in France

This study is a monocentric and open label randomized study in adult open cardiac surgery patients. Eligible patients from whom informed consent is obtained are enrolled in the study. All subjects will be implanted with the TransLoc electrodes during their primary surgery. Patients are randomized to treatment or control groups prior to surgical placement of the TransLoc electrodes.

Comparison will be made between treatment and control patients during the initial 120 hours of study, then comparison of cross-over control patients' EMG from baseline to treatment.

Further comparison of MV Time, ventilator free days and other outcome measures will be made for all patients, over the course of the 30-day treatment period, to literature on an observational basis.
