Abstract: A biostimulator, such as a leadless cardiac pacemaker, including a fixation element to engage tissue and one or more backstop elements to resist back-out from the tissue, is described. The fixation element can be mounted on a housing of the biostimulator such that a helix of the fixation element extends distally to a leading point. The leading point can be located on a distal face of the helix at a position that is proximal from a center of the distal face. The backstop elements can include non-metallic filaments, such as sutures, or can include a pinch point of the biostimulator. The backstop features can grip the tissue to prevent unscrewing of the fixation element. Other embodiments are also described and claimed.

Abstract: An electrical feedthrough assembly, which is configured to be mounted on a housing of a leadless biostimulator, comprises an electrode body including a cup having an electrode wall extending distally from an electrode base around an electrode cavity, an electrode tip mounted on a distal end of the electrode body, and a filler in the electrode cavity between the electrode base and the electrode tip, wherein the filler includes a therapeutic agent. The electrode tip is configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A pin extends proximally from the electrode base, wherein the pin is configured to be into contact with an electrical connector of an electronics assembly within the housing of the leadless biostimulator.

Abstract: Implantable medical devices (IMDs), systems, and methods for use therewith are disclosed. One such method is for use by a leadless pacemaker (LP) configured to perform conductive communication with another implantable medical device (IMD). The method includes the LP storing information that specifies when, within a cardiac cycle, the LP and the other IMD implanted in a patient are likely oriented relative to one another such that conductive communication therebetween should be successful. The method also includes the LP sensing a signal indicative of cardiac activity of the patient over a plurality of cardiac cycles, and outputting one or more conductive communication pulses, during a portion of at least one of the cardiac cycles, wherein the portion of the at least one of the cardiac cycles is identified based on the signal that is sensed and the information that is stored.

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). In an embodiment, in response to the aLP detecting a PMT, the aLP initiates a PMT PA interval, and the aLP does not inform the vLP, via an i2i communication, of an atrial sensed event that caused the PMT to be detected, thereby preventing the vLP from initiating a PV interval during the PMT PA interval. The aLP selectively terminates the PMT PA interval. Additionally, the aLP informs the vLP, via an i2i communication, of an intrinsic atrial event being detected during the PMT PA interval, or of an atrial paced event being performed in response to the PMT PA interval expiring without an intrinsic atrial event being detected during the PMT PA interval.

Abstract: Described herein is an implantable medical device (IMD) that wirelessly communicates another IMD, and methods for use therewith. Such a method can include receiving one or more implant-to-implant (i2i) communication signals from the other IMD using a communication receiver of the IMD, measuring a strength of at least one of the one or more received i2i communication signals or a surrogate thereof, and updating a strength metric based on the measured strength or surrogate thereof. The method further includes determining, based on the updated strength metric, whether to increase, decrease, or maintain the sensitivity of the communication receiver of the IMD, and responding accordingly such that the sensitivity is sometimes increased, sometimes decreased, and sometimes maintained. The method can also include selectively causing a transmitter of the IMD to transmit an i2i communication signal to the other IMD requesting that the other IMD adjust its transmission strength.

Abstract: Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes using an accelerometer of an IMD (e.g., a leadless pacemaker) to produce one or more accelerometer outputs indicative of the orientation of the IMD. The method can also include controlling communication pulse parameter(s) of one or more communication pulses (produced by pulse generator(s)) based on accelerometer output(s) indicative of the orientation of the IMD. The communication pulse parameter(s) that is/are controlled can be, e.g., communication pulse amplitude, communication pulse width, communication pulse timing, and/or communication pulse morphology. Such embodiments can be used to improve conductive communications between IMDs whose orientation relative to one another may change over time, e.g., due to changes in posture and/or due to cardiac motion over a cardiac cycle.

Abstract: Implantable medical devices (IMDs) described herein, and methods for use therewith described herein, reduce how often an IMD accepts a false message and/or reduce adverse effects of an IMD accepting a false message. Such IMDs can be leadless pacemakers (LPs), or implantable cardio defibrillators (ICDs), but are not limited thereto. Such embodiments can be used help multiple IMDs (e.g., multiple LPs) implanted within a same patient maintain synchronous operation, such as synchronous multi-chamber pacing.

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.
