Electrode arrangements for suborbital foramen medical lead

摘要

A medical lead includes a plurality of electrodes on an annular distal end portion of the lead. The electrodes may be arranged along a circle concentric with the center of a void defined by the annular portion. The annular medical lead design is well suited for application of electrical signal therapy to the suborbital nerve at its point of exit from the inferior orbital foramen in the skull.

主权项

1. An implantable medical lead comprising:
an annular distal body portion defining a central void, wherein the annular distal body portion in an unstressed state and the central void are generally flat and planar and lie in a plane, wherein an axis passes through a center of the annular distal body portion, intersecting the central void, and wherein the axis is perpendicular to the plane within which the annular distal body portion lies; and a plurality of electrodes disposed along the annular distal body portion wherein the annular distal body portion of the lead is configured to be positioned proximate the infraorbital foramen to treat facial pain by applying an electrical signal via one or more of the plurality of the electrodes.
