Clinically proven to reduce the effects of CSA

The remedē® System is a breakthrough implantable system that safely and effectively treats moderate to severe central sleep apnea (CSA) in adult patients.1

  • Stimulates a normal breathing pattern: By stimulating the phrenic nerve the remedē System activates the diaphragm, a physiologic mechanism similar to natural breathing
  • Automatic and continuous treatment: The system activates automatically at night, removing the need for patient interaction and alleviating patient compliance concerns
  • Sustained benefits: 81% reduction in the mean of the central apnea index from baseline to 6 months (versus an 11% reduction in the control group)1 and 93% reduction at 12 months.2
  • Recommended by patients: 95% of patients in the pivotal trial reported they would “elect to have the medical procedure again”2



In 2018, CMS granted the remedē System the new technology add-on payment and the transitional pass-through (TPT) payment. These programs recognize innovative medical technologies that substantially improve the diagnosis or treatment of Medicare beneficiaries.

Indications for Use
The remedē® System is an implantable phrenic nerve stimulator indicated for the treatment of moderate to severe central sleep apnea (CSA) in adult patients.

The remedē System is contraindicated for the following:


It is recommended that testing for oversensing of remedē stimulation therapy by the concomitant cardiac device occur at the time of implant and prior to initiating remedē System therapy in patients with a concomitantly implanted cardiac device. Use remedē System therapy with caution in pacemaker-dependent patients without a physiologic escape rhythm. Device interaction may lead to over or undersensing resulting in a loss of pacing. The safety and effectiveness of the remedē System during pregnancy has not been established.

See the Device Manual for detailed information regarding the implant procedure, indications, contraindications, warnings, precautions, and potential complications/adverse events.

Adverse Effects
Possible adverse events which may be associated with the use implantation and use of the remedē System include, but are not limited to, the following: adverse contrast dye reaction such as allergic reaction, pulmonary edema, or worsening renal function, adverse reaction to radiation exposure, thromboembolism, air embolism, bleeding, cardiac perforation including tamponade, hematoma, seroma, local bruising or swelling, hypotension, local wound healing issues at device implant site including wound dehiscence, pocket erosion, extrusion, movement of implanted device, keloid formation, pneumothorax, hemothorax, vascular damage, e.g., venous dissection, perforation, adverse biocompatibility reaction to the implanted system, infection, lead breakage, lead dislodgement, lead not connected or secured appropriately in device header, implantable device malfunction, requirement for more energy to stimulate the nerve or ineffective stimulation, venous occlusion, crosstalk with another implanted device, disrupted sleep, muscle fatigue or discomfort in diaphragm, chest or abdomen from appropriate stimulation, nerve dysfunction, perturbation of blood gases causing hypoxia, hypercapnea and/or hypocapnea, inappropriate sensations, worsening heart failure, respiratory status or overall health, anxiety, arrhythmia, including ventricular fibrillation, death, depression, hypotension, pain, skin irritation or local allergic reaction, thrombus or embolism, potentially leading to pulmonary embolism or stroke.

CAUTION: Federal law (USA) restricts this device to sale by or on the order of a physician. Rx only. Prior to use, please see the complete “Directions for Use” for more information on Indications, Contraindications, Warnings, Precautions, Adverse Events, and Operator’s Instructions.
