Think Surgical announces first TMINI robot cases with Stryker knee implant

Think Surgical today announced the first completed cases using the TMINI miniature robotic system with the Stryker Triathlon knee system.

Fremont, California-based Think Surgical said that multiple surgeons and hospitals have already performed cases nationwide with the latest compatible implant for the surgical robot. It plans to continue to expand the commercialization of the integrated offering this year.

Think Surgical said the cases mark a major milestone on the heels of FDA 510(k) clearance for the use of TMINI with Triathlon. It adds another option for surgeons using the miniature robot, which now works with nine different compatible options. Those include Zimmer Biomet’s Persona Knee, as well as implants from Maxx Orthopedics, Waldemar Link, Medacta and more.

TMINI originally got the FDA’s green light in May 2023. It features a wireless, robotic handpiece that assists surgeons in performing total knee replacement. Following a CT-based three-dimensional surgical plan, the TMINI robotic handpiece automatically compensates for the surgeon’s hand movement to locate bone pins along precisely defined planes. Cutting guides are then connected to the bone pins for accurate bone resection.

The integration comes about nine months after the company added Chris Marrus, who spent time in leadership positions with Mako and Stryker, among other big medtech names, as an EVP.

“The addition of the Triathlon knee system to our platform further demonstrates Think Surgical’s commitment to open platform robotics and empowering surgeon choice,” said Stuart Simpson, CEO and President of Think Surgical. “We believe that implant agnostic technology enables surgeons to deliver a more personalized solution for each patient, potentially leading to better clinical outcomes”.
