Implantable lead
First Claim
1. An implantable neural stimulator for modulating neural tissue in a patient, the implantable neural stimulator comprising:
- an enclosure shaped and configured for delivery into the patient'"'"'s body through an introducer or needle, the enclosure including an extension tubing shaped to conform to a curvature of the patient'"'"'s spinal cord, the enclosure housing;
one or more electrodes configured to apply one or more electrical pulses to the subject'"'"'s neural tissue associated with the patient'"'"'s spinal cord;
a first antenna configured to;
receive, wirelessly from a second antenna through electrical radiative coupling, an input signal containing electrical energy, the second antenna being physically separate from the implantable neural stimulator; and
a circuit coupled to the first antenna and the electrodes and configured to;
generate the one or more electrical pulses suitable for modulation of neural tissue solely using the electrical energy contained in the input signal received wirelessly from the second antenna; and
supply the one or more electrical pulses to the one or more electrodes.

Abstract
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.

18. A method for modulating a patient'"'"'s neural tissue, the method comprising:
-
delivering an enclosure into a patient'"'"'s such that one or more electrodes of an implantable neural stimulator is implanted at a target site adjacent to or near the patient'"'"'s spinal cord to modulate neural tissue, the implantable neural stimulator comprising; the enclosure including an extension tubing shaped to conform to a curvature of the patient'"'"'s spinal cord, the enclosure housing; one or more electrodes configured to apply one or more electrical pulses to the subject'"'"'s neural tissue; a first antenna; and a circuit electrically connected to the first antenna; and wirelessly delivering, through radiative coupling and from a second antenna exterior to the patient'"'"'s body, an input signal containing electrical energy to the first antenna of the implantable neural stimulator implanted at the target site such that one or more electrical pulses are generated solely from the electrical energy contained in the input signal wireless delivered through radiative coupling from the exterior location; and
wherein the generated electrical pulses are applied through the electrodes to modulate the neural tissue. - View Dependent Claims (19, 20)
