Resmed Introduces New Mirage Activa Nasal Mask With Activecell

SAN DIEGO-October 2003, ResMed (NYSE: RMD), a leading manufacturer and developer of products for the diagnosis, treatment, and management of sleep-disordered breathing (SDB), announced the release of its new Mirage Activa(tm) nasal mask with ActiveCell(tm) Technology. ActiveCell technology is ResMed's exclusive, auto-stabilizing cushion technology. It combines the proven comfort and seal of Mirage® cushion technology with an "active cell"-an inflatable chamber that expands and contracts during therapy, allowing the mask frame to move independently of the mask cushion. Together they provide a unique active seal and a dynamic defense against mask leak.

"During user preference trials, sleep techs found that the Activa required far less headgear tension to achieve a leak-free seal," says Ron Richard, VP Marketing, Americas.

"This mask was perceived to improve comfort, and it reduced complaints about air leaks. The sleep labs also commented that since the mask provided an active seal, as well as reduced leaks and other artifacts associated with performing sleep studies, the Activa would be an excellent choice for sleep lab titrations," states Richard.

• More choice of head and body positions during active sleep-Mirage Activa is so adaptable, it maintains seal even when patients roll over during sleep or rest their head in the middle of the pillow rather than on the edge.
  
• More comfort-Mirage Activa's unique technology helps reduce headgear strap tension and minimizes leak, providing more comfort for patients.
• Set & Forget convenience-ActiveCell Technology compensates for changes in strap tension, eliminating the need for continual adjustment of headgear straps.
• Fewer opportunities for "skin contact" irritation-Mirage Activa is kinder to the skin, gently maintaining superior seal.
• Reduce fitting time-Mirage Activa can help cut down on fitting time and may even help achieve accurate first-time fit. ActiveCell Technology makes this accuracy possible because it relies less on headgear strap tension to achieve an effective seal than do other masks.
• Reduce patient management costs-Improved comfort and therapy acceptance minimize the need for callbacks and returns.
• Improved compliance-Improved comfort and leak control encourage patient therapy compliance.
• Recommend confidently-Now you can confidently choose Mirage Activa to minimize mask leak and associated problems.

"We are excited by this latest advance in ResMed's mask technology," says Peter Farrell, President and CEO of ResMed. "When we showed the Activa to our Medical Advisory Board, one of the most senior members suggested that this was a truly revolutionary concept. Patients and HMEs were equally impressed with the Mirage Activa's seal, greater comfort, and decrease in headgear tension. Many stated, 'I won't use anything else until I get my Mirage Activa,' and another commented, 'My wife almost cried when I said I had to give the trial mask back.' We expect this mask to improve both CPAP acceptance and compliance."
