  • Publication number: 20160089183
    Abstract: The disclosure relates to a needle assembly for delivering a lead and methods of use. The needle assembly is configured to cut tissue and reduce the potential for cutting vulnerable bodily structures. The needle assembly includes an outer needle with a blunt tip and an inner needle with a sharp tip. The outer needle may be curved, and the inner needle may be curved. When the inner needle is rotated with respect to the outer needle, the inner needle protracts or retracts with respect to the outer needle. A stopping feature on the needle assembly may be included to resist over-rotation or over-extension. The needle assembly provides an initial path that may be further dilated for delivering a lead, such as a vagus nerve stimulation lead to a target site. The target site may be electrically tested with some embodiments.

  • Patent number: 9031861
    Abstract: Methods, systems, and computer program products are provided for measuring effectiveness of content items included in a campaign. One example method includes providing a corpus of campaigns, where a campaign defines parameters for presentation that specify circumstances under which content items are presented to users in response to requests. The corpus is filtered by identifying one or more candidate campaigns, where each of the identified candidate campaigns is associated with a geographic region and includes one or more constraints that permit pausing distribution of content items without compromising campaign goals. For each candidate campaign, one or more experimental geographic locations included in the geographic region are determined that are substantially representative of the region. Presentation of at least one of the content items is paused for a time period, and content item effectiveness is measured by comparing resource conversions for experimental and control geographic locations.

  • Patent number: 8909338
    Abstract: Electrode displacement can be detected using a thoracic impedance or conductivity signal. The thoracic impedance or conductivity signal can be filtered to attenuate cardiac contraction (stroke) and respiration components. A fluid status component of the thoracic impedance or conductivity signal can be used to detect a posture-shift related electrode displacement, such as can result from left ventricular/coronary sinus (LV/CS) lead pullback upon a recumbent to upright posture shift.

  • Patent number: 8825156
    Abstract: A system and method for detecting and treating symptoms of early decompensation utilizing a cardiac rhythm management. The system applies an electrical stimulus to the patient's heart at a first set of pacing parameters including a lower rate limit (LRL) setting, and acquires a coronary venous pressure (CVP) signal from a pressure sensor implanted in a coronary vein of the patient. An average coronary venous end diastolic pressure (CV-EDP) value is calculated from the CVP signal. The system monitors the average CV-EDP value over a predetermined interval, and dynamically adjusts the LRL setting responsive to the detection of a first or a second predetermined event based on the average CV-EDP value.
