研究概览
简要总结
Study conducted to confirm phrenic nerve stimulation using the a transvenous Phrenic Nerve Stimulator in the left jugular vein.
详细描述
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.

研究组 & 干预措施
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 jugular vein.
干预措施: LIVE Catheter (Device)
结局指标
主要结局
Successful insertion of the LIVE Catheter into the left jugular vein and stimulation of phrenic nerves
时间窗: through 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
次要结局
- Absence of device related or procedure related adverse events(through study completion, an average of 14 days)
