Medical and Surgical Devices

SRI’s integrated approach to engineering R&D has led to advanced medical devices such as novel diagnostic and drug delivery tools, and devices sized for pediatric use. We partner with large and small clients to help maintain their competitive position through development of new diagnostics and therapeutic devices from concept to commercialization. SRI helps clients:

  • Generate new product ideas

  • Meet the industry’s challenging scientific, engineering, marketing, and regulatory requirements

  • Augment their internal innovation teams to create new intellectual property

Clients benefit from SRI's extensive patent portfolio. SRI's innovations include making ultrasound practical for medical diagnostics and developing the first telerobotic surgical system, which SRI spun off as Intuitive Surgical, now a multibillion-dollar company. Surgeons throughout the world use this system, approved by the Food and Drug Administration, to help patients recover faster, with less pain and fewer complications.

Today, SRI's projects focus on

Intuitive Surgical's da Vinci surgical system in use in an operating room

Robotic surgical systems from SRI and its spin-off Intuitive Surgical are augmenting surgeons' skills.


Important diagnostic criteria for glaucoma are changes in the 3D structure of the optic disc due to optic nerve damage. We propose an automatic approach for detecting these changes in 3D models reconstructed from fundus images of the same patient taken at different times.
