Systems and Methods for the Treatment of Head Pain
Systems and methods for the treatment of head pain are provided. Systems for the treatment of head pain may include implantable neuromodulator devices configured for to provide non-contacting neuromodulation energy to one or more nerves transmitting head pain. Neuromodulation energy may be applied to one or more nerves to cause neural inhibition, blocking a head pain signal. Systems for the treatment of head pain may further include external devices configured to communicate with implantable devices.
1 . A device for treatment of head pain comprising:
an antenna configured to receive a signal and to be implanted beneath the skin in at least one of a head and neck of a subject;
at least one pair of modulation electrodes configured to be implanted beneath the skin;
a flexible carrier configured to electrically connect the antenna and the at least one pair of modulation electrodes;
wherein the at least one pair of modulation electrodes are configured to receive an applied electric signal in response to the signal received by the antenna and configured to inhibit nerve conduction through electrical pulses delivered to an afferent nerve transmitting head pain via an electric field generated by modulation electrodes.
2 . The device of claim 1 , wherein the device is physically disconnected from a power source.
3 . The device of claim 1 , wherein substantially all power of the applied electric signal is applied from external to the body and transmitted to electrodes.
4 . The device of claim 1 , having an electrode configured for location underneath the skin in a haired region and an antenna located underneath the skin in a substantially hairless region.
5 . The device of claim 1 , wherein the flexible carrier is configured to traverse an occipital ridge.
6 . The device of claim 1 , wherein the flexible carrier is configured to traverse a superior nuchal line.
7 . The device of claim 1 , wherein the flexible carrier is configured for implantation to be bounded by at least one of the trapezius muscle, semispinalis capitis muscle, longissimus capitis muscle, and inferior obliquus capitis muscle.
8 . The device of claim 1 , wherein the flexible carrier is configured such that an antenna is located behind an ear of a subject and a first carrier arm bearing an electrode extends away from the antenna to modulate the nerve when the device is implanted.
9 . The device of claim 7 , wherein the nerve is one of a greater occipital nerve, a lesser occipital nerve, a third occipital nerve, and a trigeminal nerve.
10 . The device of claim 8 , wherein a second carrier arm bearing an electrode extends away from the antenna to stimulate at least one additional nerve, wherein the at least one additional nerve includes at least one of the others of the greater occipital nerve, lesser occipital nerve, third occipital nerve, and the trigeminal nerve.
11 . The device of claim 1 , wherein the antenna is configured for implantation on connective tissue covering the skull, deep cervical fascia, auricularis superior and posterior muscle beneath the derma of the scalp.
12 . The device of claim 1 , wherein the antenna is configured for implantation between layers of derma.
13 . The device of claim 1 , wherein the antenna is configured for implantation beneath derma and above muscle.
14 . The device of claim 1 , wherein the antenna is configured for implantation beneath one layer of muscle and above another.
15 . The device of claim 1 , wherein the flexible carrier is configured to conform to the shape of the tissue on which it is implanted.
16 . The device of claim 1 , wherein at least a portion the flexible carrier is configured to receive the shape of a bony structure located beneath tissue at a location where the portion flexible carrier is implanted.
17 . The device of claim 1 , wherein the at least one pair of modulation electrodes includes a plurality of pairs of modulation electrodes configured to span the lesser, greater, and third occipital nerves.
