• An inspirational new approach to sleep-disordered breathing

    Meeting the unmet needs of a broader population of patients

A breath of fresh air

Oventus is an Australian-based, medical device company established in 2012 to meet the unmet needs of Obstructive Sleep Apneics, nasal obstructers and non-compliant CPAP users. In 2013, Oventus worked with the CSIRO to develop a new style of custom mouthguard that has the potential to help millions of snorers and people with sleep apnea sufferers around the world.

The result is the O2VentTM – a non-invasive sleep apnea treatment option with a range of oral devices incorporating Oventus Airway Technology, a unique separate airway which is built into its patented design.

The O2Vent™’s unique design directs the air flow through to the back of the throat, alleviating multiple sites of obstruction including the nose, soft palate and tongue.

The device incorporates the Oventus Airway Technology, or ‘second nose’ – a unique airway built into its patented design, allowing for breathing through the device to bypass nasal resistance which can contribute to snoring and Obstructive Sleep Apnea (OSA).

Using CAD software to create a 3D drawing of the patient’s mouth and bite, Oventus uses 3D printing technology to manufacture these custom-made medical-grade mouthguards from titanium.

Our mission

Oventus aims to become a world leader in sleep disorder treatment by commercializing our suite of revolutionary oral devices and inspiring a new paradigm of care — taking the treatment OSA to the next level by providing a real alternative for the broader population within a unique treatment platform.

Future innovation and product development

The patented airway in the O2VentTM enables exciting opportunities for dentists to offer alternative treatments to their patients. In addition to the custom oral appliance therapy range, Oventus Medical is developing a temporary device, incorporating the Oventus Airway Technology, giving dentists and patients the option to deliver immediate therapy to patients prior to progressing to a customized device.

In February 2017 Oventus Medical was announced as the lead participant in a AUD$3 Million Australian Government grant to advance research into the treatment of Obstructive Sleep Apnea. Alongside industry and scientific experts in the field, Oventus Medical will work with NeuRA (Neuroscience Research Australia) and the CSIRO (Commonwealth Science and Industrial Research Organisation) on exciting research exploring the benefit of the Oventus airway design as a treatment approach in progressive OSA treatments such as algorithms for treatment success, in-built compliance and efficacy monitoring and miniaturized CPAP pumps.

Well advanced in the product development cycle is the ‘Oventus Connect’ – a one-size-fits-all, out-of-the-box adaptor that can potentially reduce CPAP pressure requirements and remove the need for uncomfortable masks and head straps.

As well as therapeutic advantages, the Oventus Airway Technology has the ability to facilitate diagnosis and monitoring. Currently in testing is an inbuilt form of compliance monitoring and an attachment that allows a ‘Level III’ home sleep test to be completed any time, anywhere, without wires hanging off the patient and feeding data directly to an Oventus App and online treatment monitoring portal.
