Cytori Therapeutics received a Notice of Allowance from the United States Patent and Trademark Office on a patent application which broadens protection of the company's Celution System.

The more than 40 allowed claims create several new layers of protection related to the automated processing of stem and regenerative cells from adipose tissue. Key claims include: Alternative Celution System configurations beyond those covered in the company's core device patent (US Patent No. 7,390,484); Expanded protection for cosmetic and reconstructive surgery applications; and Technology within the device that optimizes intravascular delivery of adipose derived stem and regenerative cells.

Alternative configurations could accelerate processing times, be tailored to smaller volume procedures, or include a desktop version. These claims also expand the array of Celution output compositions protected by Cytori's intellectual property, so that combinations of cells, matrices, and other additives specific to needs of reconstructive and cosmetic surgery, as well as other applications are protected more broadly. The claims related to intravascular delivery are potentially applicable to a variety of clinical applications for the Celution System output, which include cardiovascular disease, liver disease, and renal failure.

Cytori's intellectual property portfolio related to the devices, methods and uses of adipose-derived stem and regenerative cells includes nine US and international patents and over 120 applications pending worldwide.

Cytori's goal is to be the global leader in regenerative medicine. The company is dedicated to providing patients with new options for reconstructive surgery, developing treatments for cardiovascular disease, and banking patients' adult stem and regenerative cells.
