At Guided Therapy Systems (GTS) our ultrasound technologies are providing new, effective and safer treatment options
without the downtime and complications associated with traditional surgeries and invasive procedures
Leaders in Ultrasonic
Imaging and Therapy
Throughout the past 25 years, GTS has become a world leader in ultrasonic imaging and therapy with technologies sold across the globe by many of the most recognizable and respected names in medical devices. Moreover, we are the first company in the world to develop and commercialize products that combine ultrasound imaging with intense therapeutic ultrasound, offering physicians the unprecedented ability to image and treat with the same equipment, thus targeting and evaluating tissue prior, during, and after a procedure.
After originally developing a minimally invasive platform for the destruction of non-resectable tumors, GTS brought intense therapeutic ultrasound to the forefront of the aesthetic device landscape through the creation of Ulthera in 2004. To this day, the Ulthera system is the only energy-based technology with an FDA indication for non-invasive tissue lift. Ulthera was recently acquired by Merz Pharma in 2014, and now with millions of procedures performed by physicians around the world, Ulthera/Merz remains as GTS’s exclusive licensee to the Ulthera technology in the professional aesthetic market.
GTS has also expanded its focus to the treatment of chronic, soft tissue injuries with the development of Actisound. This next generation ITU technology is the first and only non-invasive ablative device for pain reduction associated with chronic musculoskeletal injuries. The Actisound system received CE mark in 2018 and is currently available in select European and Asian markets.
GTS (through our exclusive partnership with Ardent Sound) is an FDA approved developer and manufacturer with ISO 13485 certification. Today, GTS has more than 250 patents issued, published, and pending in support of our imaging and intense therapeutic ultrasound products as we continue to create new technologies and make new advancements.
From non-invasive facelifts to the repair of chronic soft tissue injuries
GTS is helping people live healthier, happier, and more active lives
Our Leadership team is made up of a talented group of mechanical, electrical, and biomedical engineers and technicians,
as well as quality systems, operations, marketing, and sales professionals.
