The wireless charging startup is eliminating the need to change pacemaker batteries, forever

Shelburne, VT, June 9, 2021 -- Resonant Link, the wireless charging company spun out of Dartmouth, today announced they are bringing their breakthrough coil technology to the medical industry. The innovative wireless chargers are now available to support implantable devices like pacemakers, neurostimulators, and ventricular assist devices (VADs) for faster recharging, deeper implant depths, simpler alignment for patients, and smaller implants, with the goal of eliminating the need for surgeries to replace dead batteries forever. 

"Patients need non-invasive power to live their best lives," said Dr. Grayson Zulauf, CEO of Resonant Link. "Resonant Link's technology enables small, fast, and easy-to-use wireless charging, and we can't wait to work with our partners to make wireless power the standard for implantables."

Resonant Link's multi-layer self-resonant structure (MSRS) is a breakthrough wireless charging technology with 5-10x higher performance than is possible with existing technologies. The MSRS breaks the limits of traditional wireless charging coils by changing the geometry from 2-D to 3-D,  enabling faster recharging, deeper implant depths, simpler alignment for patients, and smaller implants. Resonant Link's chargers can reach over 99% efficiency and support implant depths up to 6 cm, all while meeting FDA-mandated temperature limits for implants. 

Resonant Link is currently working with five medical device partners across seven different patient indications, helping the industry unlock wireless power in applications where it was not previously possible. Resonant Link's chargers eliminate hospital stays, infections, discomfort, recovery time, and deaths caused by extra leads, surgeries, and drivelines.

"Drivelines are the Achilles heel of VAD therapy, complicating our patients' quality of life with chronic infections that require long-term antibiotic therapy and repeated hospitalizations," said Dr. Aditya Bansal, Surgical Director of the Mechanical Assist Device Circulatory Support Program at The Ochsner Medical Center in New Orleans, one of the busiest VAD programs in the country. "Resonant Link's boost to wireless charging efficiency is going to be a game-changer for our patients with heart failure."

 "The ability to achieve faster, more efficient charging with Resonant Link's technology represents a critical evolution in the development of the next-generation of electronic medical implantable devices," said Dr. Kevin Kwaku, Assistant Professor of Medicine and Director of Cardiac Electrophysiology at Dartmouth College.
