1. A method of implanting a stimulation lead to treat sleep-related disordered breathing, comprising:
- percutaneously inserting a distal portion of a cannula and positioning the distal portion to be adjacent to a target nerve stimulation site while maintaining a proximal portion of the cannula external to a skin surface, wherein the target nerve stimulation site includes an airway-patency related nerve;
arranging a stimulation lead to include a distal portion having a first side and a second side opposite the first side, the stimulation lead including;
at least one anchor member positioned on, and biased to extend outwardly from, the second side in a deployment position;
at least one stimulation electrode on the first side;
slidably advancing the distal portion of the stimulation lead into and through the cannula to percutaneously insert the stimulation lead until a distal portion of the stimulation lead is positioned against the nerve at the target stimulation site, wherein slidable advancement of the distal portion of the stimulation lead into the proximal portion of the cannula causes the at least one anchor member to be releasably contained against a body of the second side of the stimulation lead in a storage portion;
arranging at least the distal portion of the cannula to have a generally tubular configuration;
arranging the cannula to include a distal extension, which extends distally from the distal tip of the generally tubular distal portion of the cannula,wherein, in at least one slidable position of the stimulation lead relative to the cannula, releasably containing the at least one anchor member in the storage position comprises;
releasably covering the at least one anchor member via the distal extension of the cannula while simultaneously exposing the at least one stimulation electrode of the stimulation lead toward the nerve andslidably removing the cannula, while maintaining the position of the distal portion of the stimulation lead at the target stimulation site, to cause the at least one anchor member to extend outwardly from the second side of the stimulation lead in the deployment position against tissue adjacent the distal portion of the stimulation lead.

24. A method of implanting a stimulation lead to treat sleep-related disordered breathing, comprising:
-
percutaneously inserting a distal portion of a cannula and positioning the distal portion to be adjacent to a first target nerve stimulation site while maintaining a proximal portion of the cannula external to a skin surface, wherein the first target nerve stimulation site includes an airway-patency related nerve; arranging a stimulation lead to include a distal portion having a first side and a second side opposite the first side, the stimulation lead including; at least one anchor member positioned on, and biased to extend outwardly from, the second side; at least one stimulation electrode on the first side; slidably advancing the distal portion of the stimulation lead into and through the cannula until a distal portion of the stimulation lead is positioned against the nerve at the first target nerve stimulation site, wherein slidable advancement of the distal portion of the stimulation lead into the proximal portion of the cannula causes the at least one anchor member to be releasably contained against a body of the second side of the stimulation lead in a storage portion; arranging the cannula to include a distal extension, which extends distally from the distal tip of the generally tubular distal portion of the cannula, wherein, in at least one slidable position of the stimulation lead relative to the cannula, releasably containing the at least one anchor member in the storage position comprises releasably covering the at least one anchor member via the distal extension of the cannula while simultaneously exposing the at least one stimulation electrode of the stimulation lead toward the nerve, with the stimulation lead in the at least one slidable position, maneuvering a combination of the stimulation lead and the cannula together along the nerve and periodically applying a test stimulation signal to identify the first target nerve stimulation site from among a plurality of test stimulation sites along a length of the nerve; and slidably removing the cannula, while maintaining the position of the distal portion of the stimulation lead at the first target nerve stimulation site, to permit the at least one anchor member to extend outwardly from the second side of the stimulation lead in a deployment position against tissue adjacent the distal portion of the stimulation lead. - View Dependent Claims (25, 26, 27, 28)
