Medical device coating technology that is designed to enhance communication at the interface between human tissue and electrodes has been introduced by Biotectix (Ann Arbor, MI), a supplier of proprietary conducting polymers. Amplicoat reportedly overcomes the limitations of other conductive coatings in medical applications by offering improved durability, processability, and performance. The coating is available for license and commercialization on medical devices; other applications are currently under development.
Incorporating Photolink surface modification technology developed by SurModics Inc. (Eden Prairie, MN), Amplicoat provides a durable electrode coating that conducts ionically and electronically, resulting in lower impedance and expanded range compared with conventional coatings, according to the company.
The technology enables electrode miniaturization by allowing designers to fit more electrodes on a given lead or device while enhancing tissue-sensing resolution and localized stimulation control. Higher signal fidelity, lower power requirements, and reduced stimulation thresholds are among the benefits.
The coating can be easily applied to metal electrodes in neurostimulation, cardiac pacing, cochlear, and related devices.
Biotectix was founded in 2007 through a joint venture between the University of Michigan, Ann Arbor, and Allied Minds, a science and technology development and commercialization company.
