  • Patent number: 10245429
    Abstract: Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for percutaneous intravascular delivery of pulsed electric fields to achieve such neuromodulation.

  • Patent number: 10188862
    Abstract: A method and system is described for ensuring a state of an active implantable medical device based on the presence and persistence of a magnetic field. The output of a magnetic field sensor is monitored. The active implantable medical device is maintained in a first state, for so long as the presence of a magnetic field is detected by the magnetic field sensor, until a first interval is surpassed. If the first interval is surpassed, then a determination is made as to whether a second interval has been surpassed. If it is determined that the second interval has not been surpassed, then the active implantable medical device is transitioned into a second state. If it is determined that the second interval has been surpassed, then it is ensured that the active implantable medical device is in a predetermined one of the first and second states.

  • Patent number: 10179235
    Abstract: Methods and apparatus are provided for bilateral renal neuromodulation, e.g., via a pulsed electric field, via a stimulation electric field, via localized drug delivery, via high frequency ultrasound, via thermal techniques, etc. Such neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, neuromodulation is applied to neural fibers that contribute to renal function. In some embodiments, such neuromodulation is performed in a bilateral fashion. Bilateral renal neuromodulation may provide enhanced therapeutic effect in some patients as compared to renal neuromodulation performed unilaterally, i.e., as compared to renal neuromodulation performed on neural tissue innervating a single kidney.

  • Patent number: 10159841
    Abstract: A cardiac rhythm management system provides an increase in pacing rate as a combination of responses to three characteristics of a relative-temperature signal: a dip, a positive slope, and a positive magnitude. The relative-temperature signal is the difference between a short-term and a long-term temperature average. A dip produces a limited and temporary rate increase having a first proportionality. A positive slope produces a rate increase with a second proportionality. A positive magnitude produces a rate increase with a third proportionality. The dip response seeds the slope response to provide a seamless and immediate rate transition after a dip. The cardiac rhythm management system limits and filters the sum of the rate increases to provide a sensor indicated rate, which is used to stimulate the heart.

  • Patent number: 10065047
    Abstract: Herein is described a device and methods-of-use to treat multiple possible causes of sudden neurological dysfunction related to cardiac, cerebrovascular, or brain electrical abnormalities. The device can be employed so as to treat cardiac dysfunction such as arrhythmia and subsequently related dysfunction of the central nervous system such as stroke and seizure. Alternatively, the device can be employed so as to treat cardiac dysfunction simultaneous with treatment of dysfunction of the central nervous system. Finally, the device can be employed so as to augment the effectiveness of treating cardiac dysfunction, namely the restoration of cardiac output and blood flow to the brain, by dilating the arteries of the brain.

  • Patent number: 10045764
    Abstract: An external medical device generates a drive signal inductively coupled to an implantable coil from an external coil. A regulator module coupled to the implantable coil generates an output signal in response to the inductively coupled signal and a feedback signal correlated to an amplitude of the inductively coupled signal. A signal generator receives the output signal for generating a therapeutic electrical stimulation signal. The control module adjusts the drive signal in response to the feedback signal to control the electrical stimulation signal.

  • Patent number: 9999359
    Abstract: Systems and methods for detecting atrial tachyarrhythmias such as atrial fibrillation (AF) are disclosed. A medical system can sense a heart rate (HR) output and a hemodynamic status output. An AF detector circuit automatically determines a first detection criterion and a different second detection criterion. The first detection criterion can be more sensitive to the presence of the AF episode than the second detection criterion, and the second detection criterion can be more specific to the AF episode than the first detection criterion. The AF detector circuit detects an AF onset event using the first detection criterion and at least one of the heart rate output or the hemodynamic status output, and detects an AF termination event using the second detection criterion and at least one of the heart rate output or the hemodynamic status output.

  • Patent number: 9987482
    Abstract: A lead anchor includes a flexible housing having a first end and a second end opposite to the first end, the flexible housing defining a lead lumen forming a continuous passageway through the flexible housing. The lead anchor also includes a compressible retention ring disposed within the flexible housing and around a portion of the lead lumen. The retention ring defines an uncompressed position in which the retention ring has an elongate shape, with a major axis and a minor axis, to hold a portion of a lead received within the lead lumen. The retention ring further defines a compressed position achieved by compressing opposite ends of the major axis of the retention ring to transition the retention ring to a more circular shape that allows the lead to slidingly pass through the retention ring. Upon release of the compression, the retention ring returns to the uncompressed position.
