    摘要: Branching catheter systems with diagnostic components for detecting and isolating fluid flow problems (e.g., leaks, occlusions, etc.) and methods for detecting and isolating fluid flow problems are disclosed. Among the fluid flow problems that may potentially be detected are leaks in the branching catheter systems (e.g., cuts, disconnected components, etc.). Another fluid flow problem that may be detected using the diagnostic systems of the present invention is the presence of occlusions or other blockages that prevent fluid flow within the catheter systems. In addition to identifying that a problem exists, the diagnostic components may preferably also be used to identify the location of the fluid flow problem as discussed herein. Connectors for use in the branching catheter systems are also disclosed. Among the diagnostic components that may be used in branching catheter systems of the present are valves to control fluid flow through the various sections of the branching catheter system, fluid flow detectors to detect flow through the one or more sections of the branching catheter system and a control system for operating the diagnostic components.

    摘要: A medical device delivers a therapy to a patient. Posture events are identified, e.g., a posture of the patient is periodically determined and/or posture transitions by the patient are identified, and each determined posture event is associated with a current therapy parameter set. A value of at least one posture metric is determined for each of a plurality of therapy parameter sets based on the posture events associated with that therapy parameter set. A list of the therapy parameter sets is presented to a user, such as a clinician, for evaluation of the relative efficacy of the therapy parameter sets. The list may be ordered according to the one or more posture metric values to aid in evaluation of the therapy parameter sets. Where values are determined for a plurality of posture metrics, the list may be ordered according to the one of the posture metrics selected by the user.

    摘要: A volume sensing system for use in determining a volume of a variable volume reservoir can include a lower plunger that can have a first end adapted to move with a bottom of the reservoir. An upper plunger can be slidable relative to the lower plunger. A lower biasing member can be positioned substantially between a base of the reservoir and the upper plunger, and the upper biasing member can be positioned between the upper plunger and an interference member. The upper biasing member can have a predetermined stiffness relative to the lower biasing member such that upon movement of the lower plunger, the upper plunger can move at a predetermined fraction of the amount of movement of the lower plunger, where the predetermined fraction can be determined at least in part by the predetermined stiffness of the upper biasing member relative to the lower biasing member.

    摘要: A device, such as an implantable medical device (IMD) or a programming device, determines when a patient is attempting to sleep. When the device determines that the patient is attempting to sleep, the device determines values for one or more metrics that indicate the quality of a patient's sleep based on at least one physiological parameter of the patient. When the device determines that the patient is not attempting to sleep, the device periodically determines activity levels of the patient. Activity metric values may be determined based on the determined activity levels. A clinician may use sleep quality information and patient activity information presented by a programming device to, for example, evaluate the effectiveness of therapy delivered to the patient by the medical device.

    摘要: A medical device, such as an implantable medical device (IMD), determines values for one or more metrics that indicate the quality of a patient's sleep, and controls delivery of a therapy based on the sleep quality metric values. For example, the medical device may compare a sleep quality metric value with one or more threshold values, and adjust the therapy based on the comparison. In some embodiments, the medical device adjusts the intensity of therapy based on the comparison, e.g., increases the therapy intensity when the comparison indicates that the patient's sleep quality is poor. In some embodiments, the medical device automatically selects one of a plurality of therapy parameter set available for use in delivering therapy based on a comparison sleep quality metric values associated with respective therapy parameter sets within the plurality of available therapy parameter sets.

    摘要: A medical device system comprises a reservoir configured to store a therapeutic fluid and a medical pump configured to deliver the therapeutic fluid from the reservoir to a patient. The system also comprises a sensor that can detect a characteristic associated with the pump and a processor to determine if the characteristic detected indicates the reservoir is empty or near empty. The characteristic may comprise a property associated with the energization of an actuation mechanism configured to be energized to provide a pump stroke. The characteristic may also comprise a characteristic of a noise made by an actuator within the pump at the end of a pump stroke.
