Percutaneous Temporary Placement of a Transvenous Phrenic Nerve Stimulator for Diaphragm Pacing Using Jugular Access

Not Applicable
Completed
Conditions
Ventilator-Induced Lung Injury
Interventions
Device: LIVE Catheter
Registration Number
NCT03659552
Lead Sponsor
Lungpacer Medical Inc.
Brief Summary

Study conducted to confirm phrenic nerve stimulation using the a transvenous Phrenic Nerve Stimulator in the left jugular vein.

Detailed Description

The Lungpacer Jugular Access Feasibility System is a prototype for the Lungpacer Diaphragm Pacing Therapy System (DPTS) and consists of the LIVE Catheter, a stimulation system with a Multipole Panel Accessory, an airflow sensor and a Heart Rate Data Capture Device. The catheter is intended for inclusion in the commercial product. The stimulation system with a Multipole Panel Accessory and a Heart Rate Data Capture Device is an interim component created to enable initial safety and feasibility testing of the Lungpacer DPTS concept.

Arm && Interventions
GroupInterventionDescription
Temporary diaphragmatic pacingLIVE CatheterThere 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 jugular vein.
Primary Outcome Measures
NameTimeMethod
Successful insertion of the LIVE Catheter into the left jugular vein and stimulation of phrenic nervesthrough study completion, an average of 14 days

To determine whether in an anesthetized (sedated, intubated, and mechanically ventilated) patient the LIVE Catheter can be inserted percutaneously in the left jugular vein and, via the electrical stimulator, to transvenously stimulate one or both phrenic nerves causing the diaphragm to contract

Secondary Outcome Measures
NameTimeMethod
Absence of device related or procedure related adverse eventsthrough study completion, an average of 14 days

Assess subject for adverse events status up to 48 hours post procedure
