Percutaneous Temporary Placement of a Phrenic Nerve Stimulator for Diaphragm Pacing, a First in Human Trial

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02670460
Recruitment Status : Completed
First Posted : February 1, 2016
Last Update Posted : April 15, 2016
Information provided by (Responsible Party):
Lungpacer Medical Inc.

Brief Summary:
Study conducted to confirm phrenic nerve stimulation using the Lungpacer LIVE Catheter, confirm capture of the diaphragm and confirm that the diaphragm can be paced in synchrony with mechanical ventilator breaths.

Condition or disease Intervention/treatment Phase
Ventilator Induced Lung Injury Device: LIVE Catheter Not Applicable

Detailed Description:
This study is being conducted to determine if in an anaesthetized (sedated, intubated and mechanically ventilated) subject the LIVE Catheter can be inserted percutaneously and activated via the electrical stimulator to stimulate the left and right phrenic nerves causing the diaphragm to contract in synchrony with mechanical ventilator breaths via phrenic nerve stimulation from a transvenously delivered electrical current.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 24 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Percutaneous Temporary Placement of a Phrenic Nerve Stimulator for Diaphragm Pacing, a First in Human Trial
Study Start Date : October 2015
Actual Primary Completion Date : April 2016
Actual Study Completion Date : April 2016

Arm Intervention/treatment
Experimental: Temporary diaphragmatic pacing
There is no comparator for this study. Single site and all patients are in the treatment allocated group of temporary diaphragmatic pacing with the LIVE Catheter which is inserted via the left subclavian vein.
Device: LIVE Catheter
Placement of a temporary LIVE Catheter central venous pacing device in the left subclavian vein to pace the phrenic nerves and allow recruitment of the diaphragm muscle.

Primary Outcome Measures :
  1. Successful insertion of the LIVE Catheter into the left subclavian vien [ Time Frame: at time of procedure ]
    Confirmation by cinefluoroscopy of the insertion of the LIVE Catheter into the Left subclavian vein with the tip located in the superior vena cava

  2. Absence of device related or procedure related adverse events [ Time Frame: up to 48 hours or at time of discharge whichever comes first ]
    Assess subject AE status out to 48 hours post procedure

Secondary Outcome Measures :
  1. Phrenic nerve stimulation in synchrony with MV breaths [ Time Frame: No more than 90 minutes procedure duration ]
    Phrenic nerve stimulation in synchrony with MV breaths as defined by contraction of the diaphragm upon energy delivery.
