SELF-AFFIXING EXTERNAL CHARGING SYSTEM FOR AN IMPLANTABLE MEDICAL DEVICE

摘要

An external charging system for charging or powering an implantable medical device is disclosed which is self-affixing to the patient without the need for a holding device. The charging system can comprise two modules attached to opposite ends of a flexible member. The flexible member is bendable, and when bent will firmly hold its position on the patient. The two modules can comprise a coil module containing a charging coil, and an electronics module including a user interface and the necessary electronics for activating the charging coil to produce a magnetic charging field. Wires can couple the charging coil in the coil module to the electronics in the electronics modules. The entire assembly can be encased in a water proof sleeve having a high-friction surface, which protects the charging system and helps the charging system to adhere to the patient.
