摘要： Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include an intermediate tubular member and an inner tubular member slidably disposed within a lumen of the intermediate tubular member. A distal holding section may extend distally of a distal end of the intermediate tubular member and define a cavity therein for receiving an implantable leadless pacing device. The device may be configured to enable fluid flushing of the delivery device prior to use, to remove any air from within the device as well as providing the option of fluid flow during use of the delivery device.

摘要： Systems and methods for managing machine-generated medical alerts associated with physiological events detected from one or more patients are described herein. An alert management system may receive medical events detected from a patient and physiological data associated with patient historical medical alerts. The system comprises an alert prioritizer circuit to generate an event priority indicator for the detected medical event, using a comparison between the detected medical event and the physiological data associated with patient historical medical alerts. The system can identify prolific alert patients using the information about the historical medical alerts. The alert prioritizer circuit can adjust a priority of the detected medical event, and an output circuit can present a priority to a user or a process using the event priority indicator and the identification of prolific alert patient.

摘要： This document discusses, among other things, systems and methods to reduce ischemic or metabolic injury to a patient's heart. A system to reduce ischemic or metabolic injury to a patient's heart may include a pulse generator for generating electrical pulses or shock, a pacing lead with at least one pacing electrode configured to deliver electrical pulses received from the pulse generator to the patient's heart, a controller configured to control timing of electrical pulses to reduce wall stress of the heart, and a reservoir, fluidically coupled to a lumen and a pump, wherein the pump is configured, under control of the controller, to move contents from the reservoir through the lumen to an area of the heart with the reduced wall stress, wherein the contents include autologous respiration-competent mitochondria or other respiratory-promoting agents.

摘要： Cardiac therapy devices in the form of pacemakers and/or defibrillators including one or more leads with electrodes implanted in a vein in a posterior position in combination with one or more leads with electrodes implanted in an anterior position. The posterior position may be chosen from one or more of the azygos, hemiazygos, accessory hemiazygos, or posterior intercostal veins. The anterior position may be chosen from the internal thoracic vein, an anterior intercostal vein, or an anterior subcutaneous location. In other examples, sensors are placed for use by a cardiac monitoring or therapy system in one or more of the internal thoracic vein, the azygos vein, the hemiazygos vein, the accessory hemiazygos vein, and/or an anterior or posterior intercostal vein.

摘要： Extraction devices for extracting chronically implanted devices such as leadless cardiac pacemakers (LCP). In some cases, the extraction devices may be configured to cut, tear or ablate through at least some of the tissue ingrowth around and/or over the chronically implanted device such that a retrieval feature on the chronically implanted device may be grasped for removal of the chronically implanted device. Implantable medical devices such as LCPs may include features that facilitate their removal.

摘要： Embodiments herein relate to implantable medical devices including a power subunit with a first biocompatible electrically conductive shell configured for direct contact with an in vivo environment. In some embodiments a lithium anode can be disposed within the first biocompatible electrically conductive shell in direct electrical communication with a feedthrough pin, wherein the feedthrough pin is electrically isolated from the first biocompatible electrically conductive shell. A cathode can also be disposed within the first biocompatible electrically conductive shell and can be in direct electrical communication with the first biocompatible electrically conductive shell. The first biocompatible electrically conductive shell has a positive electrical potential. The implantable medical device further includes an electronics control subunit with a control circuit disposed within a second biocompatible electrically conductive shell. Other embodiments are included herein.

摘要： Delivery devices, systems, and methods for delivering an implantable leadless pacing device having an outer peripheral surface are disclosed. An example delivery device may include a proximal section including a distal end, and a distal holding section extending distally of a distal end of the proximal section. The distal holding section defines a cavity therein for receiving the implantable leadless pacing device, and may be configured to apply a holding force to the implantable leadless pacing device. In some cases, the distal holding section may be configured to apply a compressive force to the outer peripheral surface of the leadless pacing device when the leadless pacing device is disposed in the cavity.

摘要： This document discusses, among other things, systems and methods to adjust arrhythmia detection using physiological information of a patient, including detecting a candidate cardiac event about a threshold, displaying the detected candidate cardiac event to a user, receiving user information about the detected candidate cardiac event, and adjusting an arrhythmia detection threshold based upon the received user information.

摘要： Systems and methods for pacing cardiac conductive tissue are described. An exemplary system includes an electrostimulation circuit that may generate HBP pulses to stimulate patient physiologic conduction pathway, such as a His bundle or a bundle branch. The system includes an arrhythmia detector to detect an atrial tachyarrhythmia (AT) with intermittent ventricular conduction. A control circuit may sense ventricular activation and, in response to the detected AT indication, determine or update a His-bundle pacing (HBP) configuration. The HBP may be recursively updated on a beat-by-beat basis using the sensed ventricular activation. The electrostimulation circuit may deliver HBP according to the determined or adjusted HBP configuration to regularize ventricular rate during AT.
