SAN DIEGO, Dec. 19, 2014 /PRNewswire/ -- Sienna Labs
announced today that the U.S. Patent and Trademark Office issued
U.S. Patent No. 8,906,418 covering, among other aspects,
methods of using the company's targeted plasmonic therapy (TPT)
platform for localizing thermal damage to sebaceous glands and
hair, a key mechanism for their investigational acne treatment and
hair removal indications.
Sienna Labs' invention, entitled "THERMAL TREATMENT OF A
PILOSEBACEOUS UNIT WITH COATINGS THAT FACILITATE SELECTIVE REMOVAL
FROM THE SKIN SURFACE," specifically relates to using gold,
silver, nickel, platinum, or titanium plasmonic nanoparticles to
localize thermal damage to sebaceous glands, hair, and other
components of the pilosebaceous unit. Several claims of the patent
protect key methods for applying these plasmonic nanoparticles
to the skin, delivering them specifically into the pilosebaceous
unit, and activating the particles with light to
localize thermal damage to the gland and hair follicle.
Included in certain claims are methods for delivering particles
specifically into the pilosebaceous unit using mechanical
vibration devices including massage or ultrasound. Other key claims
relate to the use of coatings that facilitate selective
removal from the skin surface, a key feature enabling the safety
and efficacy of TPT treatment.
Todd Harris, Sienna Labs' Chief
Executive Officer, stated, "We are pleased to secure this key
patent protecting our TPT platform to treat conditions involving
the pilosebaceous unit. This patent along with 5 other patents
recently issued in the U.S. provides us with a very strong
foundation to bring our technology to market."
