International ClassA61N 001/00AbstractImproved implantable microstimulators are covered with a biocompatible polymeric coating in order to provide increased strength to the capsule and to capture fragments of the microstimulator should it become mechanically disrupted. Such coating also makes the microstimulator safer and easier to handle. The coating may include one or more diffusible chemical agents that are released in a controlled manner into the surrounding tissue. The chemical agents, such as trophic factors, antibiotics, hormones, neurotransmitters and other pharmaceutical substances, are selected to produce desired physiological effects, to aid, support or to supplement the effects of the electrical stimulation. Further, microstimulators in accordance with the invention provide systems that prevent and/or treat various disorders associated with prolonged inactivity, confinement or immobilization of one or more muscles. Such disorders include pressure ulcers, venous emboli, autonomic dysreflexia, sensorimotor spasticity and muscle atrophy. The microstimulator systems include external control for controlling the operation of the microstimulators. The control include memory for programming preferred stimulation patterns for later activation by the patient or caregiver.Field of SearchLIGHT, THERMAL, AND ELECTRICAL APPLICATIONElectrical therapeutic systems Combined with nonelectrical therapy Electrical treatment of pain Promoting tissue growth or healing Hard tissue (e.g., bone) Directly or indirectly stimulating motor muscles For walking assistance With monitoring or testing feature Control signal storage (e.g., programming) Telemetry or communications circuits Energy source outside generator body Devices placed entirely within body and means used therewith (e.g., magnetic implant locator) Ear or testing by auditory stimulus Endoradiosonde Electrode implanted in body | |
