Electrical Activation of The Diaphragm for Ventilatory Assist - Full Text View

ClinicalTrials.gov Identifier:	NCT00010374

Purpose

OBJECTIVES:

The objectives of this study are to test the Diaphragm Pacing Stimulation (DPS) System for treating chronic ventilatory insufficiency in persons with respiratory muscle paralysis. The hypothesis being tested in the clinical trial is that laparoscopic stimulation of the diaphragm at the motor point with intramuscular electrodes is safe and effective in providing significant ventilatory support to individuals who are otherwise dependant on a mechanical ventilator. Patients in our initial study group have all suffered from high-level spinal cord injury and were full-time dependant on positive pressure mechanical ventilation prior to inclusion.

Primary Outcome Measures:

Clinically acceptable tidal volume sustained over a continuous 4 hour period. [ Time Frame: Within one year after implantation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Adverse event rate from time of electrode implant compared to published adverse event rates in a similar patient population using ventilator support. [ Time Frame: After completion of the study ] [ Designated as safety issue: Yes ]
Reduction of dependence on mechanical ventilation. Improvement in the quality of life for patient and caregiver. [ Time Frame: Within one year of implantation ] [ Designated as safety issue: No ]
