Stimdia Medical Inc. Initiates FDA Approved IDE Pivotal Trial to Investigate Impact of Neuromuscular Stimulation on Mechanically Ventilated Patients

October 4, 2023


Stimdia Medical, a medical device company developing innovative technologies to improve respiratory care, today announced the initiation of its FDA approved pivotal trial to investigate the impact of phrenic nerve stimulation (PNS) on the time to liberate patients from mechanical ventilation. The ReInvigorate Study is a randomized, controlled trial that will enroll approximately 420 patients who are receiving mechanical ventilation in the intensive care unit (ICU). Patients will be randomly assigned to receive PNS therapy utilizing Stimdia’s proprietary pdSTIMTM System or standard of care alone. The primary efficacy endpoint of the ReInvigorate Study will evaluate the time to liberation from mechanical ventilation.

Dr. Kyle Cunningham, trauma and critical care physician at Atrium Health – Carolinas Medical Center had this to say about the therapy: “We are excited to have enrolled the first subject in the ReInvigorate Study. It is great to be able to investigate this new therapy in our patients who are having difficulties regaining independent breathing. This intuitive, minimally invasive approach has the potential to reverse some of the modalities that are all too common with existing ventilation techniques. We are hopeful that this therapy will make a significant difference in the lives of our patients.”

Dr. Steven Conrad, Louisiana State University, Division of Critical Care Medicine, the National Principal Investigator for the ReInvigorate Study, commented, “The pdSTIM System has the potential to introduce a novel approach to ICU patient management, assisting physicians, respiratory therapists, and nurses in expediting the liberation of patients from mechanical ventilation. I look forward to clinicians engaging in this therapy as part of the study and await the trial’s outcomes as it progresses toward completion.”

The pdSTIM System uses a minimally invasive procedure to place small leads adjacent to the phrenic nerves on each side of the neck. These leads are connected to an external console that synchronizes the delivery of therapy with inhalation. The device can be programmed to deliver electrical impulses at a specific frequency and intensity. These electrical impulses are intended to awaken and recondition the diaphragm, the primary muscle used to support breathing. Strengthening the diaphragm is believed to be an avenue towards weaning patients from mechanical ventilation more quickly.

“We are thrilled to partner with an outstanding group of clinicians to launch this pivotal trial that will investigate the potential of PNS to improve the outcomes of critically ill patients,” said Stimdia Medical CEO Tim Miller. “We believe that the pdSTIM therapy has the potential to revolutionize respiratory care, and we are dedicated to making this therapy accessible to patients as soon as possible.”

The pdSTIM System is an investigational device and is limited by federal (or United States) law to investigational use and is not available for sale or commercial use.
