  • Patent number: 10987518
    Abstract: An implantable system including an atrial leadless pacemaker (aLP) and a ventricular leadless pacemaker (vLP), and methods for use therewith, are configured or used to terminate a pacemaker mediated tachycardia (PMT). One of the aLP or the vLP detects a PMT and informs the other one. The aLP initiates a PMT PA interval that is shorter than a PA interval that the aLP would otherwise use for atrial pacing if a PMT was not detected. The vLP initiates a PMT PV interval that is longer than the PMT PA interval. If an intrinsic atrial or ventricular event is detected before PMT PA interval or the PMT PV interval expires, then these intervals will be terminated, otherwise an atrial chamber will be paced if the PMT PA interval expires, and/or a ventricular chamber will be paced if the PMT PV interval expires. This should have the effect of terminating the PMT.

  • Patent number: 10981001
    Abstract: A method of pacing a His bundle of a patient heart using a stimulation system including a memory, a pulse generator, a stimulating electrode and at least one sensing electrode includes applying a plurality of impulses through the stimulating electrode to induce a plurality of responses from the patient heart. Each impulse of the plurality of impulses is delivered at a different impulse energy corresponding to a respective output setting of the stimulation system. The response characteristics for each of the plurality of responses are measured and each impulse is assigned a classification based on whether the respective response characteristics indicate capture of one or both of the His bundle and a ventricle of the patient heart. The output setting and classification for each impulse is then stored in the memory.

  • Patent number: 10967175
    Abstract: An implantable therapy lead is disclosed herein. The lead includes an elongated lead body having a suture sleeve. The suture sleeve is supported on the lead body and has each of an outer surface and an inner surface radially inward of the outer surface. The inner surface defines a lumen through which the elongated lead body extends. The suture sleeve further includes a structure projecting radially inward and/or outward from the inner surface. The suture sleeve is compressible from a first state into a second state by applying a constrictive force to the outer surface of the suture sleeve such that, when in the second state, the structure contacts the elongated lead body, at least in part, to resist movement of the elongated lead body relative to the suture sleeve.

  • Patent number: 10967187
    Abstract: Methods and devices are provided for sensing cardiac events from electrodes located proximate to one or more atrial or ventricular sites, over a period of time that includes a detection period followed by an observation period. One or more processors declare a ventricular arrhythmia episode and a corresponding VT/VF therapy based on the cardiac events during at least the detection period. The processors delay delivery of the VT/VF therapy for a self-termination period within the observation period. The self-termination period represents a time period during which the ventricular arrhythmia episode may self-terminate. The processors analyze a stability characteristic of interest (COI) from the cardiac events sensed over at least a portion the observation period and determine an end point for the self-termination period, within the observation period, based on the stability COI. The VT/VF therapy is delivered when the VT/VF arrhythmia episode continues past the end point.

  • Patent number: 10960217
    Abstract: Disclosed herein is a delivery system for delivering a leadless pacemaker. The delivery system may include a catheter, which may be a guide catheter. The catheter includes a distal end, a proximal end opposite the distal end, a lumen extending between the distal end and the proximal end, and a locking hub operably coupled to the proximal end. The locking hub includes a lumen segment of the lumen. In one implementation, self-biasing of the lumen segment places the lumen segment out of alignment with a rest of the lumen. Deflecting the lumen segment against the self-biasing of the lumen segment places the lumen segment in coaxial alignment with the rest of the lumen. In another implementation, self-biasing of the lumen segment reduces an inner diameter of the lumen segment and actuation of the locking hub expands the inner diameter.

  • Patent number: 10925490
    Abstract: Techniques for use with an implantable medical device (IMD) reduce how often a first receiver of the IMD wakes up a second receiver thereof to reduce power consumption. A received message and/or a channel over which messages can be received is/are examined, and a value is adjusted based on results thereof. After being adjusted, the value is compared to a first threshold if the IMD is in a normal state, or compared to a second threshold if the IMD is in a noise state. If in the normal state, there is a determination whether to stay in the normal state or switch to the noise state. If in the noise state, there is a determination whether to stay in the noise state or switch to the normal state. At least the second receiver is temporarily put to sleep, if the IMD is maintained in or switched to the noise state.
