Conductive coating for medical devices

Ann Arbor, Michigan – Officials at Biotectix a developer of conductive coatings for medical devices that aim to optimize the communication between devices and physiologic systems introduced a highly durable electro-conductive polymer coating.

The new coating called Amplicoat incorporates Photolink a proprietary surface modification technology developed by Eden Prairie Minnesota-based SurModics Inc. Designed to enhance communication at the interface between human tissue and a medical device’s electrode Amplicoat overcomes the limitations of other conductive coatings including poor durability difficult processing requirements and limited performance. The new coating can be easily applied to a variety of metal electrodes providing an optimal solution for numerous medical-device applications including neurostimulation cardiac pacing electrophysiology recordings cochlear implants and gastrointestinal recording and stimulation.

“Amplicoat is a true breakthrough technology that provides a durable electrode coating that conducts both ionically and electronically resulting in lower impedance and an expanded range for safe charge delivery“ said Dr. Sarah Richardson-Burns who co-founded Biotectix with Jeff Hendricks PhD.

Amplicoat enables device electrode miniaturization offering higher numbers of electrodes for a given-sized lead or device and providing greater tissue-sensing resolution as well as more localized stimulation control. The coating enables higher signal fidelity lower power requirements and reduced stimulation thresholds.

“I am very proud of the Biotectix team. The dedication and knowledge needed to commercialize this technology was significant” said Omar Amirana MD Biotectix CEO and senior vice president of Allied Minds the parent company of Biotectix.

Biotectix is currently working with customers to incorporate Amplicoat into their medical devices. In addition there are non-medical applications for conductive coatings which are currently under development at Biotectix.
