Abstract: The present invention relates to a reflux disease treatment apparatus, apparatus, comprising an implantable movement restriction device that maintains cardia in the correct position and an implantable stimulation device adapted to engage with the cardia sphincter of a patient. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The invention can be combined with various methods for treating obesity, in particular methods that creates satiety by stretching the wall of the stomach or fills out a volume of the stomach.
Abstract: An external controller/charger system for an implantable medical device is disclosed, in which the external controller/charger system provides automatic switching between telemetry and charging without any manual intervention by the patient. The external controller/charger system includes an external controller which houses a telemetry coil and an external charging coil coupled to the external controller. Normally, a charging session is carried out using the external charging coil, and a telemetry session is carried out using the telemetry coil. However, when a patient requests to carry out telemetry during a charging session, the external charging coil is used instead of the internal telemetry coil.

Abstract: Methods, systems, and apparatus for detecting and/or validating a detection of a state change by matching the shape of one or more of an cardiac data series, a heart rate variability data series, or at least a portion of a heart beat complex, derived from cardiac data, to an appropriate template.
Abstract: Electrosurgical instruments and associated methods are provided. An electrosurgical instrument may include one or more light emitters that comprise a light source in operative communication with a power supply supportably interconnected to a handle portion. The instrument may have a toggle member with one or more selectable positions that may selectively activate any of one or more operational states of an electrosurgical electrode comprising the instrument. The toggle member may selectively activate the light emitter(s) provided on the instrument alone and/or in conjunction with the activation of one or more operational state. The handle portion may include an elastomeric handle portion that extends continuously along the handle portion and over the toggle member to seal the handle portion.
Abstract: A device for independently and controllably amplifying components of the heart sound signals without removing any component of the signal by filtering. With such a device all the signal components that carry information are still available and can be useful to a user. Filtering may however be applied to very high frequency signals, compared to the signal of interest, that are totally unrelated to the heart sounds.
Abstract: An implantable medical device operates to promote intrinsic ventricular depolarization according to a pacing protocol. When a cardiac rate exceeds a predetermined threshold, the implantable medical device modifies the pacing protocol parameters to promote AV synchrony.

Abstract: Non-invasive electrical nerve stimulation devices and magnetic stimulation devices are disclosed, along with methods of treating medical disorders using energy that is delivered noninvasively by such devices. The disorders comprise migraine and other primary headaches such as cluster headaches, including sinus symptoms that resemble an immune-mediated response (“sinus” headaches), irrespective of whether those symptoms arise from an allergy that is co-morbid with the headache. The disclosed methods may also be used to treat other disorders that may be co-morbid with migraine headaches, such as anxiety disorders. In preferred embodiments of the disclosed methods, one or both of the patient's vagus nerves are stimulated non-invasively. In other embodiments, parts of the sympathetic nervous system and/or the adrenal glands are stimulated.

Abstract: The present invention provides systems and methods for temperature-controlled ablation using radiometric feedback. An interface module may include (a) a processor; (b) a first input/output (I/O) port to receive digital radiometer and digital thermocouple signals from an integrated catheter tip (ICT); (c) a second I/O port to receive ablative energy from a generator; (d) a temperature display; (e) a patient relay; (f) a computer-readable medium storing instructions for causing the processor to: (i) calculate a temperature adjacent to the ICT based on the digital radiometer and thermocouple signals and operation parameters; (ii) cause the temperature display to display the calculated temperature; and (iii) close the patient relay to pass ablative energy received on the second I/O port to the first I/O port; and (g) a temperature control subsystem to regulate the ablative power based on the calculated temperature.

Abstract: An implantable medical lead exhibits reduced heating under MRI conditions. The lead includes a multi-layer coil conductor including an inner coil layer, a middle coil layer disposed around the inner coil layer, and an outer coil layer disposed around the middle coil layer. Each of the coil layers is characterized by one or more of a filar thickness, a coil pitch, or a coil diameter configured such that the coil conductor exhibits a high inductance when exposed to MRI radiation. Each of the coil layers is electrically connected to the other coil layers to provide parallel conductive paths resulting in a coil conductor resistance suitable for defibrillation lead applications.

Abstract: Techniques for determining whether one or more leads are not adequately connected to a patient, e.g., for ECG monitoring, are described. The techniques involve injection of an integrated signal (which includes a test signal) into one lead, and monitoring the driven lead and the response at the other leads, including the common mode and the difference between the other leads. These “lead-off” detection techniques may be provided by an external defibrillator that provides three-wire ECG monitoring. Techniques for determining a type of a cable coupled to a defibrillator are also described. The cable-type identification may allow a defibrillator to, for example, operate in either a three-wire ECG monitoring mode or a therapy mode, based on whether a three-wire ECG cable or a defibrillation cable is coupled to the defibrillator.

A per-fabricated header, for receiving conducting leads and for connecting the conducting leads to the electronic circuitry, has a header fastener part also formed of metal. The header is fastened to the housing by metal-to-metal welding of the housing fastener part and the header fastener part at a distance from the housing.
Abstract: A tissue sensor probe and corresponding electromagnetic surgical ablation system are disclosed. The system includes an ablation probe coupled to a generator, a controller coupled to the generator, and a tissue sensor probe coupled to the controller. The tissue sensor probe includes an electrically-conductive enclosure configured to shield a temperature sensor from electromagnetic radiation produced by the ablation probe. At least a portion of the electrically-conductive enclosure is made of a high thermal-conductivity material. A material of high thermal-conductivity is disposed in the electrically-conductive enclosure in thermal association with the thermally-conductive material of the electrically-conductive enclosure. The temperature sensor is disposed in the material of high thermal conductivity so as to electrically isolate the temperature sensor from the enclosure.
