摘要： Systems and methods for managing communication strategies between implanted medical devices. Methods include temporal optimization relative to one or more identified conditions in the body. A selected characteristic, such as a signal representative or linked to a biological function, is assessed to determine its likely impact on communication capabilities, and one or more communication strategies may be developed to optimize intra-body communication.

摘要： Systems and methods for rate-adaptive pacing are disclosed. In one illustrative embodiment, a medical device for delivering electrical stimulation to a heart may include a housing configured to be implanted on the heart or within a chamber of the heart, one or more electrodes connected to the housing, and a controller disposed within the housing. The controller may be configured to sense a first signal and determine a respiration rate based at least in part on the sensed first signal. In at least some embodiments, the controller may be further configured to adjust a rate of delivery of electrical stimulation by the medical device based at least in part on the determined respiration rate.

摘要： An implantable medical device for implantation into a patient may include a housing, a pulse generation circuit disposed at least partially within the housing, a plurality of electrodes electrically coupled to the pulse generation circuit, the plurality of electrodes being exposed external to the housing, and a controller operatively coupled to the pulse generation circuit. The controller may be configured to command the pulse generation circuit to deliver a phasic conducted communication pulse via at least two of the plurality of electrodes. Additionally, the phasic conducted communication pulse may comprise a first phase having a first polarity followed by a second phase having an opposite second polarity, wherein the second phase may have a duration of less than 60 microseconds, and wherein the first phase having may have a duration of between five percent and eighty percent of the duration of the second phase.

摘要： Systems and methods for communicating between medical devices. In one example, an implantable medical device comprising may comprise one or more electrodes and a controller coupled to the electrodes. The controller may be configured to receive a first communication pulse at a first communication pulse time and a second communication pulse at a second communication pulse time via the one or more electrodes. The controller may further be configured to identify one of three or more symbols based at least in part on the time difference between the first communication pulse time and the second communication pulse time.

摘要： Systems, methods, and devices for determining occurrences of a tamponade condition are disclosed. One exemplary method includes monitoring an accelerometer signal of a leadless cardiac pacemaker attached to a heart wall, determining if a tamponade condition of the patient's heart is indicated based at least in part on the monitored accelerometer signal, and in response to determining that the tamponade condition is indicated, providing a notification of the tamponade condition for use by a physician to take corrective action.

摘要： An implantable medical device (IMD) may be deployed within a patient's right atrium at a location near a right atrial appendage of the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an IMD may be implanted within the right atrial appendage. The IMD may include an expandable anchoring mechanism configured to secure the IMD in place.

摘要： An implantable pulse generator includes a device housing containing pulse generator circuitry and a header connected to the device housing. The header includes a core assembly defining first and second lead bore cavities sized for receiving terminal pins of leads, first and second labels, and an outer layer. The first label is printed onto a surface of the core assembly proximate the first lead bore cavity and includes a first color. The second label is printed onto the surface of the core assembly proximate the second lead bore cavity and includes a second color different from the first color. The outer layer is overmolded over the core assembly so as to encapsulate the first and second labels and to allow access to the first and second lead bore cavities.
