Embodiment Construction

[0032] Spinal cord stimulation can treat chronic neuropathic pain, especially low back pain and radiculopathy, poor blood vessel supply to the feet or hands, sore throat, and more. In various embodiments, a neurostimulation system may deliver electrical stimulation to targeted neural tissue without cables and without inductive coupling to power a passive implanted stimulator. This can be used to treat pain or a variety of other symptoms. Target neural tissue may, for example, be in the spinal column including: spinothalamic tract, dorsal horn, dorsal root ganglion, dorsal root, dorsal column fibers, and peripheral nerve tracts leaving the dorsal column and brainstem, and all cranial nerves , abdominal nerves, thoracic nerves, or trigeminal nerves, cortical tracts, deep cranial tracts and any sensory or motor nerves.

[0033] The neurostimulation system may include an implantable introductory device comprising a housing housing one or more conductive antennas (e.g., dipole or ...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application 61 / 471,496, filed April 4, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] This instruction sheet relates to implantable neurostimulators. Background technique [0004] A variety of therapeutic in vivo electrical stimulation techniques can treat neurological diseases. These techniques may utilize a subcutaneous battery-operated implantable pulse generator (IPG) connected to one or more implantable electroconductive therapy devices. These implants have multiple failure modes including mechanical dislodgement, implant-extension tube impingement, infection, and uncomfortable irritation from the IPG and extension tube. Different types of spinal cord stimulation (SCS) delivered therapy devices have been used to provide therapeutic pain relief. These introductory device configurations typically include cylindrical p...
