Percutaneous Temporary Placement of a Phrenic Nerve Stimulator for Diaphragm Pacing

Brief description of study

A randomized clinical trial to investigate the use of the temporary Diaphragm Pacing Therapy System (DPTS) to rehabilitate the diaphragm in mechanically ventilated patients who have failed at least two weaning attempts. The goal is to strengthen and rehabilitate the diaphragm to liberate the patient more quickly from mechanical ventilation.

Detailed Study Description

Mechanical ventilation (MV) is a life saving technology but can also cause damage to the lungs and diaphragm such as ventricular induced diaphragmatic dysfunction (VIDD). Research has shown that after being on mandatory MV and sedated the diaphragm begins to atrophy within as short as 18 hours. The Lungpacer Diaphragm Pacing Therapy System (DPTS) is a temporary therapy that consists of the Lungpacer IntraVenous Electrode Catheter (LIVE Catheter) and the Lungpacer Control Unit system. The LIVE Catheter is a proprietary central venous catheter that incorporates pacing electrodes in strategic areas that align with the left and right phrenic nerves. The LIVE Catheter can also be used for fluid delivery like any other central venous catheter. The randomized clinical trial will investigate the safety, effectiveness and performance of the Lungpacer DPTS. By stimulating the diaphragm through daily therapy sessions, with the intention of exercising and rehabilitating the diaphragm muscle so the patient may be able to be more quickly liberated from MV. The patient population includes those who have been mechanically ventilated for greater than or equal to 96 hours (4days), have failed two or more spontaneous breathing trials (SBT), and were not hypervolemic during the latest spontaneous breathing trial. Patients must have resolution of the initial indication for placement on mechanical ventilation before entering the trial.
