Described herein are methods for use with an implantable system including at least an atrial leadless pacemaker (aLP). Also described herein are specific implementations of an aLP, as well as implantable systems including an aLP. In certain embodiments, the aLP senses a signal from which cardiac activity associated with a ventricular chamber can be detected by the aLP itself based on feature(s) of the sensed signal. The aLP monitors the sensed signal for an intrinsic or paced ventricular activation within a ventricular event monitor window. In response to the aLP detecting an intrinsic or paced ventricular activation itself from the sensed signal within the ventricular event monitor window, the aLP resets an atrial escape interval timer that is used by the aLP to time delivery of an atrial pacing pulse if an intrinsic atrial activation is not detected within an atrial escape interval.

Ventricular far-field sensing to guide atrial leadless pacemaker and beyond

Computer implemented methods and systems are provided that comprise, under control of one or more processors of a medical device, where the one or more processors are configured with specific executable instructions. The methods and systems include sensing circuitry configured to define a sensing channel to collect biological signals, memory configured to store program instructions, a processor configured to implement the program instructions to at least one of analyze the biological signals, manage storage of the biological signals or deliver a therapy, and communication circuitry configured to wirelessly communicate with at least one other implantable or external device, the communication circuitry configured to transition between a sleep state, a partial awake state and a fully awake state. When in the fully awake state, the communication circuitry is configured to execute tasks and actions associated with a communications protocol startup (CPS) instruction set that includes an advertisement scanning related (ASR) instruction subset and a non-ASR instruction subset. When in the partially awake state, the communication circuitry is configured to execute, as the ASR instruction subset, transmit advertising notices over one or more channels according to a wireless communications protocol, scan the one or more channels for a connection request from an external device. When a connection request is not received, return to the sleep state, without performing actions or tasks associated with the non-ASR instruction subset of the CPA instruction set.

System and method for managing Bluetooth Low Energy advertising

A method is provided for establishing a communication session with an implantable medical device ('IMD'). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The advertisement period and the scan period of the protocol are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.

Medical device and method for managing advertisement period

Systems and methods for managing bi-directional communication between an external device (ED) and an implantable medical device (IMD) are provided. The method comprises receiving an active ED configuration and a request for communications parameters to be used with the active ED configuration. The method further comprises identifying a pre-existing configuration, from a collection of pre-existing configurations that match the active ED configuration, the collection of pre-existing configurations having an associated collection of predefined parameter sets. The method further determines a resultant parameter set from the collection of predefined parameter sets based on the pre-existing configuration identified and returns the resultant parameter set in connection with the request, the resultant parameter set to be utilized by the ED for bi-directional communication with the IMD.

Methods for implanting a pulse generator (PG) within a pectoral region of a chest of a patient and devices having the PG. The PG has a housing that includes a PG electrode. Methods also include implanting at least one lead having first and second electrode segments with the first electrode segment positioned along an anterior of the chest of the patient and the second electrode segment positioned along at least one of a posterior of the patient or a side of the patient. The first and second electrode segments are positioned subcutaneously at or below an apex of a heart of the patient, wherein the PG electrode and the first and second electrode segments are configured to provide electrical shocks for antiarrhythmic therapy.

System and method for managing Bluetooth low energy advertising

A computer implemented method and system to detect P-waves in cardiac activity is provided. The system includes memory to store specific executable instructions. One or more processors are configured to execute the specific executable instructions for obtaining far field cardiac activity (CA) signals for a series of beats, applying a P-wave template to at least one sub-segment of the CA signals to obtain an alignment indicator and calculating an amplitude dependence (AD) indicator based at least in part on the P-wave template and the at least one sub-segment. The system analyzes the alignment indicator based on a first criteria, compares the AD indicator with a second criteria, designates a candidate P-wave to be an actual P-wave based on the analyzing and comparing and records results of the designating.

Method and system for detecting low level P-waves

Methods, devices and program products are provided for determining an early battery depletion condition for a battery powered device. The method determines a charge consumption drawn externally from a battery cell by the device for a select period of time, obtains a measured cell voltage for the battery cell of the medical device, calculates a projected cell voltage based on the charge consumption and usage conditions, and declares an early depletion condition based on a relation between the measured and projected cell voltages.

Methods for implanting a puke generator (PG) within a pectoral region of a chest of a patient and devices having the PG. The PG has a housing that includes a PG electrode. Methods also include implanting at least one lead having first and second electrode segments with the first electrode segment positioned along an anterior of the chest of the patient and the second electrode segment positioned along at least one of a posterior of the patient or a side of the patient. The first and second electrode segments are positioned subcutaneously at or below an apex of a heart of the patient, wherein the PG electrode and the first and second electrode segments are configured to provide electrical shocks for antiarrhythmic therapy.

Disclosed herein is a battery with a pouch-type enclosure for use with an implantable electronic device. The battery may have greater than 20 megaohms of isolation between the anode and the external surface of the pouch-type battery enclosure and the cathode and the external surface of the pouch-type battery enclosure. The battery may have a pouch-type enclosure with a contoured shape, including a cathode, anode, and electrolyte disposed within the pouch-type enclosure. The cathode and/or anode may have variable thicknesses. The variable thickness anode and/or cathode may be contoured in shape to at least partially provide the contoured shape of the pouch-type enclosure.
