SANTA ROSA -- Sonoma Orthopedic Products today announced the company closed a series D financing round totaling $22 million that will be used to fund salesforce expansion, new products, clinical trials and the acquisition of certain key assets of NovaLign Orthopaedics Inc.

The Santa Rosa company has a patented technology for the minimally invasive repair of fractured bone.

Ascension Health Ventures led the latest round of funding. Also participating were Split Rock Partners, Legacy Life Sciences, EDF Ventures, MedVenture Associates, DFJ InCube Ventures, Emergent Medical Partners, and Asset Management Partners.  In connection with the financing, Dr. Walter Lin of Ascension Health Ventures has joined Sonoma's board of directors.

"We are pleased by the level of support provided by Sonoma's distinguished new and existing investors, who share our vision for advancing the field of minimally invasive fracture repair," said Glen Coleman, Sonoma Orthopedic Products president and chief executive officer.

Founded in 2006 in Larkfield, 31-employee Sonoma Orthopedic expanded last year into a 10,000-square-foot space on Westwind Boulevard near  Charles M. Schulz–Sonoma County Airport.

The company recently won a patent from the U.S. Patent and Trademark Office for its core technology, the first of several, said founder and Chief Operating Officer Charles Nelson.
