(UPDATED: See below.)

Oraya Therapeutics, a stealthy medical-device developer in Menlo Park, Calif., raised $4 million in a first funding round, VentureWire reports (subscription required). Essex Woodlands Health Ventures provided the funds.

From the VentureWire story:

Based in Menlo Park, Calif., Oraya is a stealth-mode medical device company founded in June 2006. According to the filing, the company's board includes Essex Woodlands Partner Guido J. Neels and Adjunct Partner Michael E. Gertner. Peter Cohn, a partner at the Menlo Park office of law firm Orrick Herrington & Sutcliffe LLP, was listed as secretary of Oraya.

UPDATE: This item still seems to draw a steady stream of traffic, so I thought I'd also direct readers to a later, more detailed item on Oraya's second-round funding and the entrepreneurial background of founder Michael Gertner that we published in January.
