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

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.
