Engineering the First Nationwide 3D Printing Network for the Veterans Health Administration – Part 2

Recently, the Veterans Affairs Center for Innovation (VACI) launched the first nationwide medical 3D printing network through a collaboration with Stratasys, one of the largest manufacturers of 3D printers globally. As part of this effort, five Stratasys 3D printers were installed in VA hospitals across the country- Seattle, Albuquerque, San Antonio, Boston and Orlando – building upon the incredible work of existing 3D printers across the VA. Dr. John Hoy (Associate Chief of Staff, Radiology at the Orlando VA) has been working with his dedicated team to envision best-practices for connecting hospitals across the country so physical resources (such as printers) and VA employee expertise are available to all Veterans. This will allow Veterans to access customized 3D printed anatomical models, assistive technology devices, orthotics, and other tools- empowering them to do things they love.

Already, the power of these new 3D printers and connectivity of the network are being demonstrated in two distinct examples of multi-site collaboration:

Gary Brayshaw, a Veteran in Washington state, is an avid outdoorsman. Chopping wood was a daily occurrence and a way of life before his hand contracture made this impossible. A determined occupational therapy hand specialist, Mary Matthews-Brownell, contacted the Seattle VA 3D printing leadership and explained her vision for a custom 3D printed splint for her patient. Seattle leadership then identified the ideal network specialist for the project – Ben

Ben and Mary worked together bringing her vision to life – a rugged 3D printed custom orthotic enabling this Veteran to confidently pick up an axe again. Mary’s original hand crafted orthotic was CT scanned in Seattle and this digital file was sent to Ben who optimized design and 3D printed a fit test prototype.  As Gary liked the fit, the final orthotic will be printed from a softer, more rugged material. If the orthotic does break, Gary doesn’t need to have a new one hand fabricated.  A perfect replica orthotic can be 3D printed from the digital design file and mailed to Gary – saving him travel time and allowing Mary to serve other Veterans.

Albuquerque VA hospital’s Spinal Cord Injury Center for therapy, Ben Salatin (a clinical rehabilitation engineer and 3D printing project co-lead) noted his difficulty activating toggle switches on the wheelchair joystick due to lack of finger function.

The  switches could have been bypassed with external buttons placed elsewhere on Ismael’s wheelchair, but this added complexity.  Ben designed and 3D printed a press-on adapter to enlarge the toggle switch so Ismael could easily access the controls directly.  After a week of testing, Ismael pronounced the design a success.  This design will now be shared with other VA hospitals for Veterans to leverage.  With only a few quick design changes, it can also be customized to fit the unique needs of any Veteran.

The overarching vision for 3D printing is universal availability at all 168 VA hospitals across the country –  accelerating development of personalized healthcare, tools and technologies for Veterans and their families.

She received her Bachelor’s degree in Art History from Stanford University and her MD and PhD in Neurosciences from University of California, San Diego School of Medicine. She completed radiology residency training and a cardiovascular imaging fellowship at Brigham and Women’s Hospital, Harvard Medical School, and a body imaging fellowship at the University of Washington. As an innovation specialist with the VA Center for Innovation, Dr. Ripley collaborates with a talented and diverse group of physicians, orthotists, prosthetists, engineers, administrators and information technologists across the VA system who—together— are reimagining the meaning of individualized patient care. Amongst other things, the VA 3D Printing Leadership Team hopes to understand how patient-specific 3D printing can improve the safety and quality of diagnosis and interventions such as surgery and minimally invasive procedures, improve patient education, shared decision-making, and informed consent and improve how patients engage with their surroundings.
