AeroPace Diaphragm Pacing Therapy for Ventilator-Dependent Patients

Official title: A Post-Approval Multicenter Study to Assess the Continued Safety and Effectiveness of the AeroPace® System - The AERO-PAS Study

Run by Lungpacer Medical Inc. · NCT07477054 · Data updated 2026-11-12

This post-approval study tests whether the AeroPace system can safely and effectively help patients on long-term mechanical ventilation who haven’t been able to wean after 96 hours.

Is this trial a fit for you?

Likely a good fit

Adults 18 and older on mechanical ventilation for ≥96 hours who have not weaned and failed a spontaneous breathing trial.

Probably not a fit

Patients who have features that preclude diaphragm pacing or who are on ECMO, neuromuscular blockade, or have conditions that prevent catheter insertion or accurate assessment.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This was a prospective, multicenter, single-arm study collecting real-world data after the AeroPace diaphragm pacing therapy was approved. It enrolled adults on mechanical ventilation for at least four days who had failed a spontaneous breathing trial and continued to require support. The primary focus is 30-day safety and continued effectiveness of the AeroPace system when used in routine clinical practice. Data from participating centers will help characterize outcomes related to diaphragmatic function and weaning in this specific population.

Why it matters

Potential benefit: If successful, the therapy could aid weaning from ventilation and improve diaphragmatic function for patients who have struggled to wean.

How similar studies have gone: Other pilot and post-market data on diaphragm pacing therapies have shown potential benefits in selected patients, but results vary and this approach remains investigational for broader use.

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Are 18 years or older, and,
2. Will have been mechanically ventilated for ≥96 hours (4 days) by the time of Catheter insertion, and,
3. Have not weaned from MV, and,
4. Have failed an institutional SBT within 48 hours of enrollment.

Exclusion Criteria:

1. Invasive mechanical ventilation \>90 days.
2. Currently on extracorporeal membrane oxygenation (ECMO).
3. Weaning failure due to hypervolemia.
4. Medical history (including imaging) or known anatomy that prevents percutaneous insertion of the Catheter into the intended thoracic vein on the left side.
5. Clinically overt congestive heart failure that is preventing weaning.
6. Currently being treated with neuromuscular blockade that could affect phrenic nerve / diaphragm contraction.
7. Pre-existing neurological, neuromuscular or muscular disorder that could affect the respiratory muscles.
8. Pre-existing severe chronic pulmonary fibrosis.
9. Known pleural effusions occupying greater than one third of the pleural space on either side.
10. BMI \>70 kg/m2.
11. Known or suspected phrenic nerve paralysis.
12. Any electrical device (implanted or external) that may be prone to interaction with, or interference from the AeroPace System, including neurological pacing/stimulator devices, cardiac pacemakers and defibrillators.
13. Current hemodynamic instability
14. Uncontrolled sepsis or septic shock.
15. Current or untreated bacteremia.
16. Expecting withdrawal of life support and/or shift to palliation as the goal of care.
17. Known or suspected to be pregnant or lactating.
18. Currently being treated in another clinical trial studying an experimental treatment that could affect the study primary outcome.
