Abstract: Extraction devices for extracting chronically implanted devices such as leadless cardiac pacemakers (LCP). In some cases, the extraction devices may be configured to cut or tear 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.

Abstract: Implanted medical device data is received, where the data was sensed by a first lead portion and a sensor over a time period. The number of detected noise events sensed by the first lead portion is counted based on applying first noise detection criteria to the data sensed by the first lead portion. The number of detected noise events over the sensor is counted based on applying second noise detection criteria to the data sensed by the sensor. The mean number of detected noise events is calculated for the first lead portion and sensor based on the number of noise events sensed by the first lead portion and the number of noise events sensed by the sensor. Potential lead failure in the first lead is recorded if the number of detected noise events over the first lead is greater than the mean number of noise events by at least 5%.

Abstract: A delivery and deployment device may include a handle assembly and a shaft extending distally from the handle assembly. A device containment housing may be coupled to a distal region of the shaft and may extend distally therefrom. The distal containment housing may be configured to accommodate at least a portion of the IMD therein. The IMD may, for example, be a leadless pacemaker, a lead, a neurostimulation device, a sensor or any other suitable IMD. A plurality of electrodes may be distributed about an exterior surface of the device containment housing such that at least some of the plurality of electrodes may be positioned to test a potential IMD deployment location before deploying the IMD.

Abstract: Systems and methods for detecting cardiac arrhythmias such as an atrial fibrillation (AF) are described herein. The AF detection system includes a sensor circuit to sense a physiological signal, a heartbeat processor to recognize a plurality of beat patterns using cycle length of two more consecutive cardiac cycles. The beat patterns can be indicative of temporal relationship between the consecutive cardiac cycles. The heartbeat processor may generate a repetitiveness indictor based on a statistical measurement of various beat patterns. The AF detection system includes an arrhythmia detector to detect an episode of AF based on the repetitiveness indictor, and to discriminate the AF from other arrhythmias of atrio-ventricular conduction abnormalities.

Abstract: Methods and device for determining a pacing vector for delivering an electrostimulation therapy are described. An implantable medical device may be configured to determine an anode capture threshold and a cathode capture threshold for a first anode and cathode pair of electrodes, switch a polarity of the first anode and cathode pair of electrodes, and determine an anode capture threshold and a cathode capture threshold for the first anode and cathode pair of electrodes having the switched polarity. The implantable medical device may be further configured to compare a cathodal capture threshold for the anode and cathode pair having the switched polarity to the anodal capture threshold of the first anode and cathode pair of electrodes and select either an anode or a cathode for delivering an electrostimulation therapy based at least in part on the comparison. Other methods and systems are also contemplated and described.

Abstract: A heart rate variability or heart rate variation can be identified using sensed and/or paced heart beats. One or more patient metrics, such as a variability index or a variation index, can correspond to the identified heart rate variability or heart rate variation. The patient metrics can be used to identify a need for a particular therapy, such as a rate-responsive pacing therapy. The patient metrics can be used to identify patients at an elevated risk of death. Methods and systems to identify therapy indications or at-risk patients are provided. In an example, a patient risk profile can be adjusted, such as in response to an identified patient heart rate variability or heart rate variation. In an example, a rate-responsive pacing mode can be used to adjust the patient risk profile.

Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a tubular member and a distal holding section extending distally of a distal end of the tubular member and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may facilitate vascular delivery of the pacing device to a left side of a patient's heart. In one example, a distal tip portion may extend distal of the distal holding section and may be actuated between a closed and an opened position. When in the closed position, the distal tip portion may have a tip that can puncture or engage an opening in a septum between a left atrium and a right atrium of a patient's heart. Actuating the distal tip portion to an opened position may be utilized to dilate the puncture or opening in the septum.
