American Shared Hospital services announces contract to supply Leksell Gamma Knife Perfexion System


A leading provider of turnkey technology solutions for advanced radiosurgical and radiation therapy services, announced today that it has entered into a contract to supply a Leksell Gamma Knife® Perfexion™ system to Smilow Cancer Hospital at Yale-New Haven, New Haven, Connecticut.  This new Perfexion system, the seventh placed by AMS to date, will replace an existing Gamma Knife supplied by AMS and is expected to begin treating patients in the fourth quarter of 2009.


The 14-story, 500,000-square-foot Smilow Cancer Hospital is scheduled to open in October 2009, and will be the most comprehensive cancer care facility between Boston and New York City.

The Leksell Gamma Knife Perfexion system refines and expands the therapeutic potential for radiosurgery procedures in the brain, skull, cervical spine and head & neck regions, and is widely regarded as the most advanced stereotactic radiosurgery system available today.

AMS Chairman and Chief Executive Officer Ernest A. Bates, M.D., said, "Yale-New Haven Hospital has been a Gamma Knife customer of ours for over ten years.  We are pleased that our creative financing solutions have made possible this upgrade to next-generation radiosurgery technology at an affordable price."

About Leksell Gamma Knife® Perfexion

Leksell Gamma Knife Perfexion maintains full clinical compatibility with the classic Leksell Gamma Knife and is supported by efficacy and outcome data from over 500,000 treated patients worldwide and thousands of peer-reviewed scientific articles, making it a proven choice for radiosurgery of the brain.  According to Elekta, Leksell Gamma Knife Perfexion reduces unwanted body dose to the patient by up to 100 times compared with competing technologies, which is particularly important for treatment of children and women of childbearing age, and allows for a dramatically increased treatable volume, which is expected to increase the number of patients that can benefit from Gamma Knife surgery.  Elekta estimates that the fully automated and efficient single push-button approach can save 3-5 working weeks of physician time per year at an average Gamma Knife center.
