摘要:
Implantable devices require a protection method, both to protect the body from implant contamination and the implant electronics from corrosion. Encapsulation is a critical component for the design of a medical device implant –it acts as a barrier between the active electronics and the inside of the human body. Currently, bulky feedthroughs and headers must be incorporated in the design of medical devices, such as implantable pulse generators (IPG), to reduce the risk of water ingress. This means that efforts to miniaturize such implantable devices are hindered. An electrical stimulation device is provided comprising a treatment pulse generator unit and an implantable electrode unit; the treatment pulse generator unit being configured and arranged to wirelessly transmit the treatment energy pulses; the implantable electrode unit comprising an electrode unit encapsulation layer, configured and arranged to resist the ingress of fluids from a human or animal body; and being configured and arranged to wirelessly receive at least a portion of the treatment pulsed energy from an associated energy transmitter through the encapsulation layer when the associated energy transmitter is proximate. The electrode unit further comprises one or more stimulation electrodes,and is configured and arranged to be rigidly attached to the treatment pulse generator unit such that one or more energy transmitters are proximate the associated energy transmitter. By providing a separate electrode unit comprising an encapsulation layer and transmitting the signals wirelessly to the electrode unit through the encapsulation layer, the electrode unit may be separately optimized for implantability. In addition, the dimensions of the implantable electrode unit may also be minimized as the functionality is divided between the electrode unit and the pulse generator unit. In addition, the rigid attachment may provide improved retention of alignment and/or proximity –this may improve the stability and r
