摘要： The present disclosure generally relates to systems and methods for detecting awake or sleep states and/or monitoring respiratory events (e.g., inspiration and expiration) for a subject using measurements obtained from at least an accelerometer and a magnetometer, and methods of treating medical conditions related thereto (e.g., obstructive sleep apnea). Positional data generated by the accelerometer or magnetometer is then used by a controller to control the magnetometer and accelerometer according to different sampling rates and to reset signal filters based at least in part on a detection that a body orientation of the subject has changed after detecting that the subject is asleep.

摘要： Pressure sensors having ring-tensioned membranes are disclosed. A tensioning ring is bonded to a membrane in a manner that results in the tensioning ring applying a tensile force to the membrane, flattening the membrane and reducing or eliminating defects that may have occurred during production. The membrane is bonded to the sensor housing at a point outside the tensioning ring, preventing the process of bonding the membrane to the housing from introducing defects into the tensioned portion of the membrane. A dielectric may be introduced into the gap between the membrane and the counter electrode in a capacitive pressure sensor, resulting in an improved dynamic range.

摘要： An electrode lead may comprise a flexible circuit that includes a planar dielectric substrate including an elongated lead substrate portion having opposing ends, an electrode carrying substrate portion disposed on one end of the lead substrate portion, and a connector substrate portion disposed on the other end of the lead substrate portion, wherein the lead substrate portion is pre-shaped into a three-dimensional structure. The flexible circuit may further include an electrically conductive trace extending from the connector substrate portion to the electrode carrying substrate portion, a first window formed in the connector substrate portion to expose the electrically conductive trace to form a connector pad, and a second window formed in the electrode carrying substrate portion to expose the electrically conductive trace to form an electrode pad. The electrode lead may further comprise a lead connector that incorporates the connector substrate portion.

摘要： A medical device of a medical system is configured for communicating with an external programmer over a wireless communications link. The medical device comprises a wireless communications module configured for receiving a first unencrypted version of a random number and a first encrypted version of the random number from the external programmer over the wireless communications link. The medical device further comprises control circuitry configured for performing an authentication procedure on the external programmer based on the first unencrypted version of the random number and the first encrypted version of the random number, and preventing the external programmer from commanding the medical device to perform an action unless the authentication procedure is successful.

摘要： An electrode lead comprises a lead body, connector contacts affixed to the proximal end of the lead body, and a cuff body affixed to the distal end of the lead body. The cuff body is pre-shaped to transition from an unfurled state to a furled state, wherein the cuff body, when in the furled state has an inner surface for contacting a nerve and an overlapping inner cuff region and an outer cuff region. The electrode lead further comprise electrode contacts circumferentially disposed along the cuff body when in the furled state, such that at least one of the electrode contacts is located on the inner surface of the cuff body, and at least another of the electrode contacts is located between the overlapping inner and outer cuff regions. The electrode lead further comprises electrical conductors extending through the lead body respectively between the connector contacts and the electrode contacts.
