    摘要: Methods and systems for determining whether an implanted catheter used to deliver fluids to a selected internal delivery site is malfunctioning. The malfunctions may include that the infusion section of the catheter is not located at or has migrated away from the selected internal delivery site, is leaking, is blocked, etc. The determination is made by analyzing the pressure modulation of fluid within the catheter and determining whether the pressure of the fluid in the catheter is modulated by physiologic pressure changes experienced at the selected internal delivery site. The physiologic pressure modulations at the selected internal delivery site may be caused by, e.g., cardiac activity, respiration, changes in patient's posture, etc.

    摘要: Posture-responsive therapy is delivered by the medical system based on posture state input from only one of multiple posture sensors at any given time. An example implantable medical system includes a first posture sensor and a second sensor. A processor controls therapy delivery to the patient based on at least one of a patient posture state or a patient activity level determined based on input from only one of the first or second posture sensors. In some examples, one of multiple posture sensors of an implantable posture-responsive medical system is used to automatically reorient another posture sensor (of the system), which has become disoriented. The disoriented posture sensor may be automatically reoriented for one or more posture states at a time.

    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: The disclosure is directed to a capacitive pressure sensor, and the assembly of a capacitive pressure sensor, that may be used within an implantable medical pump. In one example, a housing ferrule that encloses one capacitive plate and includes at least one protrusion for attaching a support structure of the capacitive plate. The at least one protrusion defines a smaller inner diameter as a reference point for securing the support structure while the ferrule provides a larger inner diameter to allow the support structure to tilt inside the ferrule to orient the capacitive plate into a desired plane. Despite manufacturing irregularities, the capacitive plate can be mounted in the desired plane parallel to another capacitive plate, a diaphragm, mounted to an edge of the ferrule. In another example, an assembly tool provides a stage to orient the capacitive plate and support structure within the ferrule at a desired depth.

    摘要: A method for monitoring the status of an implanted catheter includes monitoring changes in pressure within a lumen of a catheter associated with physiological parameters (“physiological pressure”) and changes in pressure within the lumen of the catheter associated with bolus infusion of fluid into the catheter or bolus withdrawal of infusion from the catheter (“bolus pressure”). Methods that employ monitoring both physiological pressure and bolus pressure can provide information that cannot be obtained from monitoring physiological pressure or bolus pressure alone.
