MEDICAL LEAD FOR TREATING OBSTRUCTIVE SLEEP APNEA (OSA) WITH ELECTRICAL STIMULATION

摘要

A lead for delivering electrical stimulation therapy is described. The lead includes an elongated member defining a longitudinal axis, one or more electrodes disposed at a distal end of the elongated member, a plurality of collars located along the longitudinal axis, and one or more fixation members. At least one of the fixation members is a bow-like member having a first connection point to a first collar of the plurality of collars and a second connection point to a second collar of the plurality of collars. The distal end of the elongated member is configured for insertion in a tongue of a patient such that the one or more electrodes are implanted proximate to one or more motor points of a protrusor muscle within the tongue of the patient and the bow-like member of the one or more fixation members is implanted within tissue of the tongue.
