Invuity Launches Advanced Visualization System For Spinal Surgeries

Invuity, a leading developer of state-of-the-art surgical visualization technology, today debuted its illuminated Eigr™ Taylor Retractor System at the American Academy of Orthopaedic Surgeons Annual Meeting (Feb. 7-10) at the Moscone Center in San Francisco. Invuity’s advanced technology provides surgeons with unparalleled access and visualization.

Invuity will demonstrate its illuminated Taylor retractor system throughout the meeting at its booth (4262).

The Eigr™ Taylor Retractor System is designed to enhance visualization and tissue retraction during spinal surgery, including posterior lumbar discectomy and decompression procedures. At least 600,000 Americans have spinal surgery every year. Invuity’s system integrates the company’s proprietary Eigr™ (pronounced eye-gr) illumination technology into optimized Taylor retractors, making the anatomy appear brighter and sharper while remaining thermally cool. The system includes six retractors in multiple sizes for varying patient anatomies.

“I have noted a dramatic improvement in operative field visibility with Eigr technology,” said Dr. James Bruffey, an orthopedic surgeon in La Jolla, California.  “I am able to see much better and with more definition, even in deeper incisions. Perhaps most importantly, this technology allows me and my assistant to see clearly without the need for a headlight, which makes me more efficient and improves safety.”

The highly engineered Eigr™ technology utilizes unique optical structures to control light output to a targeted operative space. By directing light from multiple angles and efficiently managing light across a broad output surface, Eigr™ virtually eliminates shadows, back reflection, glare and thermal effects such as overheating. Invuity’s Taylor retractors are also ergonomically designed so that surgeons have greater comfort and maneuverability.

“In the past few months, Invuity has launched several key surgical devices incorporating our Eigr™ technology that provide critical value to surgeons by enhancing intra-operative visualization, particularly within less invasive procedures,” said Philip Sawyer, chief executive officer of Invuity. “As a result, interest in our spinal products is growing rapidly.”

Last year, Invuity closed $17.6 million in Series C funding designed to support the commercial launch of multiple new product introductions. The funding was led by InterWest Partners, and current investor Kleiner Perkins Caufield & Byers also participated.

Invuity offers a suite of products that integrate Eigr™ technology and address procedures in a variety of surgical specialties including spine, orthopedics, head and neck, and breast oncology.
