ST PAUL, Minn.--(BUSINESS WIRE)--Restore Medical, Inc. (NASDAQ:REST), developer of the innovative Pillar® Palatal Implant System – a simple, minimally-invasive treatment to help individuals suffering from snoring and mild-to-moderate obstructive sleep apnea (OSA) – today announced enrollment of the first patients in a clinical study evaluating the use of Pillar palatal implants in combination with continuous positive airway pressure (CPAP) therapy in the treatment of mild to moderate OSA. Many patients have difficulty complying with CPAP therapy if high levels of airway pressure are necessary for their therapy to be successful. This clinical study will evaluate a combined therapeutic approach of stiffening the soft palate with Pillar palatal implants, thereby allowing the reduction of CPAP pressures and potentially improving patient compliance with CPAP therapy.
