Historic Milestone by Brinter (+video)
Updated: Oct 8
October 7, 2026 – Brinter, a medical device company developing multi-material 3D-bioprinted regenerative implants, today announced the successful implantation of the first fully 3D-bioprinted regenerative implant in a live large-animal model at Colorado State University.
The procedure was successfully completed on October 6, 2026, at Colorado State University, Institute for Translational Medicine. This represents a major milestone for Brinter's rotator cuff implant and regenerative medicine as a whole.
This achievement marks an important step in the evolution of Brinter's 3D bioprinting technology—from primarily research and development applications toward first implantable, FDA-approved, regenerative medical devices, designed to function inside the body. Our initial focus is addressing the high failure rates of rotator cuff repair by supporting tissue regeneration and improving healing.
“This is a historic moment for Brinter and an incredibly important milestone for our team. What began as an idea to use our multi-material 3D-bioprinting technology to manufacture regenerative implants is now being tested inside a living large-animal model,” said Tom Alapaattikoski, Co-Founder and CEO of Brinter.
The study will evaluate the rotator cuff tendon implant's performance, tissue integration, biocompatibility, and regenerative response in a clinically relevant large-animal model. Initial data are expected in approximately six weeks.
“We are incredibly proud of our team and grateful to our research partners who helped us reach this historic milestone,” said Theo Arhio, COO.
Brinter’s technology combines proprietary multi-material 3D bioprinting platform with resorbable biomaterials to create regenerative implants designed to provide mechanical support while enabling tissue integration and the body’s natural healing processes. Brinter's initial research program is focused on rotator cuff repair, where failed healing and cost pressures remain major clinical challenges.
