Abstract
A method and system for providing electrical stimulation to tissue includes implanting one or more battery-free microtransponders having spiral antennas into tissue. Energy is provided wirelessly to the plurality of microtransponders. Tissue is stimulated using the energy.
Claims3
A linear implantable device array comprising:
- a plurality of implantable devices, each of the plurality of implantable devices comprising:
- and inductive antenna;
- an energy storage circuit connected to the inductive antenna and storing energy received at the inductive antenna;
- and a stimulator circuit connected to the energy storage circuit and applying pulses to a plurality of biocompatible electrodes;
- and
- connecting material, connecting each of the implantable devices to form a physically-connected array of implantable devices such that the electrodes of each of the implantable devices are at a fixed distance apart from the electrodes of another of the implantable devises, wherein the implantable devices are collectively housed in a cannula, and wherein the cannula is configured to implant the physically-connected array of implantable devices into tissue at a single injection point.
3 more elements
A method of providing electrical stimulation to tissue comprising:
- implanting into tissue an array of independent implantable devices, each independent implantable device including an inductive antenna and electrodes, wherein each of the independent implantable devices is physically connected to at least another one of the independent implantable devices in the array with a connecting material such that the electrodes of one of the independent implantable devices are held at a fixed distance apart from the electrodes of another one of the independent implantable devices by the connecting material, and wherein the physically-connected array of independent implantable devices is housed within a cannula prior to being implanted into the tissue;
- providing inductive energy through skin to each of the inductive antennas at the same time using a single control device;
- communicating instructions from the single control device to each of the independent implantable devices using the inductive energy;
- receiving response replies from each of the independent implantable devices by the single control device;
- and
- stimulating the tissue using one or more of the independent implantable devices in accordance with the instructions.
