摘要： System and methods for adjusting electrical therapy based on impedance changes are disclosed herein. A method in accordance with a particular embodiment includes applying a therapeutic electrical signal to a patient via an implanted portion of a patient stimulation system that includes a signal delivery device in electrical communication with a target neural population of the patient. The electrical signal is delivered in accordance with a signal delivery parameter having a first value. Using the implanted portion of the patient stimulation system, a change in an impedance of an electrical circuit that includes the signal delivery device is detected. Based at least in part on the detected impedance change, the method can further include automatically adjusting the value of the signal delivery parameter from the first value to a second value different from the first, without human intervention.

摘要： An inductive element adapted for use in implantable intravascular devices (IIDs) having an elongate form factor with a cross-section. The inductive element includes a core that has an outer surface contour that corresponds to the form factor. A set of elongate, or oblong, windings are situated lengthwise along the major length dimension of the inductive element. The windings are also situated to direct a magnetic field along a radial direction in relation to the elongate form factor. In one embodiment the form factor is generally cylindrical and the cross-section is generally round.

摘要： A method of estimating the blood flow rate of a heart ventricle assist device which is positioned externally of, or implanted in, a patient. The assist device comprises a blood pump having a rapidly rotating, electrically powered impeller, and comprises briefly interrupting power to the impeller to cause its rotation to slow. From this, blood viscosity can be estimated, which viscosity is used to obtain real time, estimated blood flow rates and pressure heads. Apparatus for accomplishing this is disclosed.
