Abstract: A medical system for obstructive sleep apnea (OSA) treatment includes therapy delivery circuitry configured to output one or more electrical stimulation signals to a tongue of a patient; sensing circuitry configured to sense one or more compound muscle action potential (CMAP) signals, wherein the one or more CMAP signals are generated in response to the delivery of the one or more electrical stimulation signals; and processing circuitry configured to: cause the therapy delivery circuitry to output the one or more electrical stimulation signals to the tongue; receive information indicative of the one or more CMAP signals from the sensing circuitry; determine, based on the one or more CMAP signals, one or more therapeutic stimulation parameters for the OSA treatment; and cause the therapy delivery circuitry to deliver therapeutic electrical stimulation signals according to at least the determined one or more therapeutic stimulation parameters.

Abstract: Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include a cylinder that engages the lead body. The length of contact of the cylinder to the lead body is at least 0.010″ long while average contact pressure is no greater than (10 pounds per inch)/(contact length). Adequate electrical isolation is achieved, even when a debris particle is present between the inner cylinder and the lead body while insertion force remains acceptable.

Abstract: Implantable medical leads and/or lead extensions include a band that encapsulates a portion of conductors of the lead and/or lead extension. The band may be reflowed in order to provide the encapsulation of the conductors. The band may further be used to create a seal together with the surrounding lead body and an additional object such as a stiffener rod, stylet tube, and/or molding stylet, to allow a proximal area of a lumen of the lead body to be injection molded while prevent the injection molding material from proceeding past the band. When a stiffener rod is present in a proximal area of the lead and/or lead extension, additional stiffness is provided to the lead body to resist buckling of the lead body during insertion of the proximal end. The band may be bonded to the stiffener rod to fix the position of the stiffener rod relative to the conductors.

Abstract: An assembly for forming a medical lead includes a lead body, a plurality of electrical conductors extending about a longitudinal axis of the lead body, and at least one segmented electrode preform that includes an electrically conductive ring and an insulator portion within the electrically conductive ring. The electrically conductive ring includes a plurality of electrode portions and a plurality of raised portions that alternate continuously around the ring. Each of the plurality of electrode portions is continuous at a radius from a center of the electrically conductive ring that corresponds to an outer perimeter of the medical lead. The insulator portion has a plurality of projections each extending into a respective raised portion of the ring beyond a radius that corresponds to the outer perimeter of the medical lead. Each respective electrode portion is electrically coupled to a respective electrical conductor of the plurality of electrical conductors.

Abstract: Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include an inner cylinder that engages the lead body. The inner cylinder is surrounded by a gap to either an outer cylinder of the seal or to surrounding structures of the implantable medical device. The inner cylinder has freedom of movement within the gap such that movement of the lead body that is off-axis relative to a centerline of the lead bore causes movement of the inner cylinder that is providing the seal. In this manner, the seal engagement to the lead body is maintained during this off-axis movement of the lead body.
