IMPLANTABLE LEAD

摘要

An implantable wireless lead includes an enclosure, the enclosure housing: one or more electrodes configured to apply one or more electrical pulses to a neural tissue; a first antenna configured to: receive, from a second antenna and through electrical radiative coupling, an input signal containing electrical energy, the second antenna being physically separate from the implantable neural stimulator lead; one or more circuits electrically connected to the first antenna, the circuits configured to: create the one or more electrical pulses suitable for stimulation of the neural tissue using the electrical energy contained in the input signal; and supply the one or more electrical pulses to the one or more electrodes, wherein the enclosure is shaped and arranged for delivery into a subject's body through an introducer or a needle.

1. An implantable lead for modulating excitable tissue in a body of a patient comprising
an enclosure shaped and configured for delivery into the patient's body through an introducer or needle; one or more electrodes housed within the enclosure and configured to apply one or more electrical impulses to excitable tissue; a first antenna housed within the enclosure and configured to receive, from a second antenna through electrical radiative coupling, an input signal containing electrical energy, the second antenna being physically separate from the implantable lead; and a circuit coupled to the first antenna and the electrodes and configured to generate the electrical impulses suitable for modulation of excitable tissue using the electrical energy contained in the input signal and to supply the electrical impulses to the electrode.
