The Restera Implant — Next-Generation OSA Treatment

An innovative new implant in clinical trials, showing a 63% immediate AHI reduction on the first night.

Treating Sleep Apnoea with the RESTERA Implant



A Future Treatment Option for Obstructive Sleep Apnoea
For patients seeking sleep apnoea treatment without CPAP, the Restera represents one of the most exciting emerging options available from a sleep apnoea surgery London specialist at the snoring clinic Harley Street. The Restera innovative solution involves the use of a small implant, only 1.5 mm wide, which is currently undergoing clinical trials. This implant is designed with a linear electrode array, comprising four different electrodes that can be combined to create a customisable electrical field. The procedure for inserting the implant involves the use of ultrasound guidance to place the electrode near a targeted nerve. Once the surgeon is satisfied that the implant is close to the desired location, it is tested for a favourable response before being anchored into place. Typically, this procedure takes approximately 10 minutes from start to finish, depending on the surgeon’s expertise and the patient’s cooperation.

"First class surgeon. I cannot recommend highly enough. I was using NHS and a CPAP but struggling. Mr Veer diagnosed me with severe sleep apnea using DISE and planned and carried out surgeries using the latest techniques. Mr Veer is very professional, easy to talk to and engaging in style. You cannot go wrong in using him." Google Review, 5 stars — Golf Ninja
The research has focused significantly on positioning the implant near the hypoglossal nerve, which directly influences the genioglossus muscle of the tongue. By stimulating this nerve, we can help alleviate obstructive sleep apnoea by ensuring the tongue maintains a forward position, thus keeping the airway open during sleep. Additionally, they have explored stimulating the Ansa cervicalis nerve, which aids in bringing the airway forward and opening the throat. This method focuses on rotating the larynx into a more favourable position for airway openness by stimulating the strap muscles located at the front of the neck.

One of the major advantages of this implant is that multiple implants can be placed in a single patient, providing a highly customisable approach to treatment. This flexibility allows us to effectively treat patients with varying degrees of severity and even those with a high BMI. Over the past year, we have published six studies that demonstrate the effectiveness of this implant. Notably, there was an almost immediate 63% reduction in the Apnoea-Hypopnea Index (AHI) on the very first night, which is a significant improvement compared to other therapies such as Inspire and Genio, which require about two months of healing before showing any active treatment effects.

To date, this implant has been successfully inserted into 63 patients worldwide. One of the key benefits of this technology is that, due to the global shortage of ENT surgeons and the relatively simple and quick insertion process, we can treat more patients than traditional implant methods. The Restera company (also known as Invicta Medical) is currently in the Series B round of investment, seeking additional funds to support the completion of longer feasibility studies and aiming for a commercial launch in 2027.

This implant holds the promise of transforming the treatment landscape for sleep apnoea by offering a quick, effective, and customisable solution. With continued research and development, we believe this technology has the potential to significantly improve the quality of life for many patients suffering from sleep apnoea and related conditions. The next phase of the research will focus on refining the technology further, expanding our clinical trials, and preparing for a wider commercial rollout. They are confident that this approach will set a new standard in the treatment of sleep apnoea and pave the way for future advancements in the field. As an obstructive sleep apnoea specialist London, Professor Vik Veer sees the Restera as a transformative option for patients who need sleep apnoea treatment without CPAP, and patients can enquire about its availability at the snoring clinic Harley Street.

"Mr. Vik Veer was highly professional, attentive, and clear in guiding me through a complex sleep-related issue. He took the time to understand my history, listened carefully, explained both the sleep study and DISE results in detail, and offered a structured treatment plan. I felt well cared for and informed throughout the process. Highly recommended." Google Review, 5 stars — Dogacan Kurucu


Frequently Asked Questions

The Restera implant is a next-generation minimally invasive device for obstructive sleep apnoea. It is only 1.5 mm wide and uses a linear array of four electrodes to stimulate the hypoglossal nerve or Ansa cervicalis nerve, keeping the airway open during sleep. The implant is inserted under ultrasound guidance in approximately 10 minutes and is currently in clinical trials.

Unlike the Inspire hypoglossal nerve stimulator, the Restera implant showed an almost immediate 63% reduction in AHI on the very first night of use, whereas Inspire and the Nyxoah Genio device require approximately two months of healing before delivering active treatment. Restera is also smaller, quicker to insert, and can be placed in multiple locations in a single patient, allowing a highly customisable approach.

The Restera implant is being studied in patients with obstructive sleep apnoea who cannot tolerate or do not respond adequately to CPAP. One advantage over existing implants is that it may be suitable for patients with a higher BMI. A thorough assessment including drug-induced sleep endoscopy (DISE) is needed to determine suitability.

Professor Vik Veer at the snoring clinic Harley Street is closely involved in research and clinical work related to next-generation sleep apnoea implants. The Restera device is currently in clinical trials and is expected to become commercially available around 2027. Patients interested in this or other forms of sleep apnoea surgery London can contact his clinic to discuss current options.

Because the Restera implant is inserted via a quick, minimally invasive procedure taking approximately 10 minutes under ultrasound guidance, recovery is expected to be significantly faster than traditional implant surgeries. The implant can begin stimulating the nerve from the very first night, unlike other devices that require a healing period.

The Restera implant is one of the most promising options for sleep apnoea treatment without CPAP. Its early results showing an immediate 63% AHI reduction on the first night compare favourably with other non-CPAP approaches. Professor Vik Veer, an obstructive sleep apnoea specialist London, offers a full range of non-CPAP treatments including the Restera, Inspire, surgical procedures, and mandibular advancement devices.
