What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a device called the LinguaFlex™ Tongue Retractor, which is placed in the tongue to help keep the airway open during sleep. It targets adults with moderate to severe sleep apnea. By preventing the tongue from blocking the airway, it aims to reduce snoring and sleep apnea episodes.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, you must agree not to use any additional therapy for sleep apnea during the study.

Is the LinguaFlex Tongue Retractor (LTR) safe for humans?

The safety of tongue suspension devices, like the LinguaFlex Tongue Retractor, has been studied in various forms. Some studies have shown promising results, but issues like device fracture, slippage, or migration have been noted. In animal studies, certain materials used in these devices have shown the ability to remodel into a strong, tendon-like structure over time.12345

What data supports the effectiveness of the treatment LinguaFlex Tongue Retractor (LTR) for obstructive sleep apnea?

Research on similar treatments, like the Mandibular-Lingual Repositioning Device (MLRD), shows significant improvement in sleepiness and overall condition in patients with obstructive sleep apnea. Additionally, techniques that control tongue position, such as tongue retention components, have been found effective in maintaining open airways during sleep.25678
