Sonoma Orthopedic Products, founded in 2005 in Santa Rosa, has developed two implant devices for repairing fractures of the wrist and collarbone. The devices are implanted inside the bone by an orthopedic surgeon using minimally-invasive techniques. The company says the approach results in less pain and better healing. Sonoma disclosed a new $1.5 million venture funding round in a filing with federal securities regulators. To date the startup has raised more than $25 million, including a $12 million funding round in 2009. Named investors include EDF Ventures, Asset Management Co., Split Rock Partners and MedVenture Associates. Sonoma develops and manufactures orthopedic implants for wrist, ankle, and collarbone fractures. Its patented WaviBody® and ActivLoc® technologies are used in least-invasive surgical procedures to provide fixation for fractures at the core of the bone. The implants are inserted in a canal in the center of the bone, require much smaller incisions with minimal tissue damage, and have no prominence outside the bone. The company intends to use the funds to receive FDA clearance on its new ankle implant, launch it, and scale commercially. Sonoma received $12M in funding from First Analysis, which also placed Tracy Marshbanks on the company’s board. Founded in 2005 and based in Santa Rosa, California, and outside Chicago, the company focuses on minimally invasive fracture fixation solutions. Sonoma Orthopedic Products develops and commercializes least invasive, fracture‑specific implant systems using proprietary technology for orthopedic trauma. The company is led by President and CEO Glen Coleman and was founded by COO Charles Nelson. It intends to use recent funding to launch new products, expand its U.S. sales network, and support key clinical trials. Sonoma also plans to use proceeds to acquire certain key assets of NovaLign Orthopaedics, Inc. In conjunction with the financing, Dr. Walter Lin of Ascension Health Ventures joined Sonoma’s board of directors. The company is based in Santa Rosa, California. Sonoma Orthopedic, based in Santa Rosa, Calif., develops the WaviBody, a flexible device inserted into a fractured bone that then becomes rigid to set breaks anatomically. The company aims to commercialize its first two products, positioning the WaviBody as an alternative to casts, braces and bone plates. Sonoma is currently testing the WaviBody on 50 patients with wrist fractures to evaluate whether they heal faster using the device. Wrist and clavicle fractures have proved problematic because existing treatments can be unwieldy or fail to heal injuries quickly or correctly; Sonoma targets those shortcomings. Financially, the company has raised $25 million to date, including the most recent $12 million round. Sonoma says it has enough runway to last through 2011. Sonoma Orthopedics is a stealthy spinal-device maker based in Santa Rosa, Calif. The company is developing devices that repair or reinforce bones from the inside. It is operating under a stealth profile while advancing those spinal repair technologies. Financially, Sonoma raised at least $10 million in a second funding round. MedVenture Associates led that round, joined by existing investors EDF Ventures, Asset Management, Halo Fund and Angel's Forum. The company previously raised $3 million in a first round last April.
