  • Publication number: 20190069815
    Abstract: In some examples, a medical system includes a medical device. The medical device may include a housing configured to be implanted in a target site of a patient, a light emitter configured to emit a signal configured to cause a fluorescent marker to emit a fluoresced signal into the target site, and a light detector that may be configured to detect the fluoresced signal. The medical system may include processing circuitry configured to determine a characteristic of the fluorescent marker based on the emitted signal and the fluoresced signal. The characteristic of the fluorescent marker may be indicative of a presence of a compound in the patient, and the processing circuitry may be configured to track the presence of the compound of the patient based on the characteristic of the fluorescent marker.

  • Publication number: 20170304516
    Abstract: The present invention relates to devices, systems, and methods for controlling the concentration of potassium in dialysate in a closed loop potassium control system. The devices, systems, and methods can be compatible with any dialysis system including sorbent-based dialysis systems, single pass dialysis systems, or other multi-pass dialysis systems. The systems can use closed loop potassium control over potassium concentration in the dialysate to reduce the probability of patient arrhythmias. The potassium concentration can be controlled and personalized to a patient using certain predetermined patient parameters. Related systems, algorithms, and control systems are contemplated for optimizing the potassium concentration in the dialysate.

  • Publication number: 20170050022
    Abstract: The disclosure describes techniques for delivering electrical stimulation to decrease the ventricular rate response during an atrial tachyarrhythmia, such as atrial fibrillation. AV nodal stimulation is employed during an atrial tachyarrhythmia episode with rapid ventricular conduction to distinguish ventricular tachyarrhythmia from supraventricular tachycardia and thereby prevent delivering inappropriate therapy to a patient.

  • Patent number: 9289613
    Abstract: An electrical parameter value indicative of an impedance of an electrical path between a first medical device implanted within a patient and a second medical device implanted within the patient may be determined by generating and delivering an electrical signal between electrodes connected to the first medical device and sensing the electrical signal with two or more sense electrodes connected to the second medical device. In some examples, the electrical parameter value indicative of the impedance may be used to detect a system integrity issue, such as relative movement between the first and second medical devices, such as between leads connected to the medical devices, or a lead-related condition. In other examples, the determined impedance may indicate a transthoracic impedance of the patient.

  • Patent number: 9192769
    Abstract: Techniques for minimizing interference between the first and second medical devices or between the different therapy modules of a common medical device are described herein. In some examples, a medical device may include shunt-current mitigation circuitry and/or at least one clamping structure that helps minimize or even eliminate shunt-current that feeds into a first therapy module of the medical device via one or more electrodes electrically connected to the first therapy module. The shunt-current may be generated by the delivery of electrical stimulation by a second therapy module. The second therapy module may be enclosed in a common housing with the first therapy module or may be separate, e.g., a part of a separate medical device.

  • Patent number: 9101772
    Abstract: A method of stimulation therapy and an apparatus for providing the therapy which addresses cardiac dysfunction including heart failure. The therapy employs atrial pacing pulses delivered to a heart after the atrial refractory period and timed so that they will not cause a ventricular contraction. These atrial pacing are timed to achieve beneficial effects on myocardial mechanics (efficacy) while maintaining an extremely low level of risk of arrhythmia induction. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.

  • Patent number: 9042982
    Abstract: Methods and devices for determining optimal Atrial to Ventricular (AV) pacing intervals and Ventricular to Ventricular (VV) delay intervals in order to optimize cardiac output. Impedance, preferably sub-threshold impedance, is measured across the heart at selected cardiac cycle times as a measure of chamber expansion or contraction. One embodiment measures impedance over a long AV interval to obtain the minimum impedance, indicative of maximum ventricular expansion, in order to set the AV interval. Another embodiment measures impedance change over a cycle and varies the AV pace interval in a binary search to converge on the AV interval causing maximum impedance change indicative of maximum ventricular output. Another method varies the right ventricle to left ventricle (VV) interval to converge on an impedance maximum indicative of minimum cardiac volume at end systole. Another embodiment varies the VV interval to maximize impedance change.

  • Patent number: 8676310
    Abstract: An implantable medical device (IMD) may include a battery dedicated to providing cardiac stimulation therapy and a separate power source that provides power for electrical stimulation therapy. Such a configuration preserves the battery dedicated for providing cardiac stimulation therapy even if the second power source is depleted. As an example, the IMD may comprise a cardiac stimulation module configured to deliver at least one stimulation therapy selected from a group consisting of pacing, cardioversion and defibrillation. The IMD further comprises a electrical stimulation module configured to deliver electrical stimulation therapy, a first power source including a battery, wherein the first power source is configured to supply power to the cardiac stimulation module and not to the electrical stimulation module, and a second power source. The second power source is configured to supply power to at least the electrical stimulation module.
