Abstract

A neurostimulation patch is affixed to a patient's skin (e.g., via a medical skin adhesive) and provides stimulation energy for an implanted lead. The patch may be used for SCS trials or other applications where is it desirable to avoid implanting a stimulation device within a patient. Circuitry in the patch generates stimulation signals and couples these signals to the implanted lead. The signals may be coupled to the lead via a direct physical connection or via a wireless connection. In some embodiments, the neurostimulation patch is configured in a manner that enables the patch to be placed immediately above the puncture site where an associated percutaneous lead passes through a patient's skin, thereby protecting the puncture site and facilitating secure routing of the lead.

Claims5

Dependent claims

A neurostimulation system for stimulating a nervous system of a patient, comprising:

a patch attachable to the skin of the patient, the patch including a body member comprising a substantially flat bottom portion;
a neurostimulation circuit located within the body member of the patch, the neurostimulation circuit configured to radiate optical energy;
and
a stimulation lead subcutaneously implanted in the patient, the stimulation lead having a first end and a second end, with first end implanted proximate the target area of the patient to be stimulated, and the second end implanted subcutaneously in the patient proximate the patch;
and
a lens positioned in the body member of the patch and connected to the neurostimulation circuit, the lens to facilitate transmission of optical energy from the neurostimulation circuit through the skin of the patient to the second end of the stimulation lead.
