摘要： A method of making a feed-thru connector assembly includes inserting a conductor within an opening within a housing of a pulse generator and dispensing a sealant in a gap between the conductor and portions of the housing adjacent to the conductor that define the opening of the housing and curing the sealant to form a seal comprising a polyisobutylene cross-linked network.

摘要： Methods and devices for testing and configuring implantable medical device systems. A first medical device and a second medical device communicate with one another using test signals configured to provide data related to the quality of the communication signal to facilitate optimization of the communication approach. Some methods may be performed during surgery to implant one of the medical devices to ensure adequate communication availability.

摘要： An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.

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： Methods and devices for configuring the use of a motion sensor in an implantable cardiac device. The electrical signals of the patient's heart are observed and may be correlated to the physical motion of the heart as detected by the motion sensor of the implantable cardiac device in order to facilitate temporal configuration of motion sensor data collection that avoids detecting cardiac motion in favor of overall motion of the patient.

摘要： Near-field energy transmitters for charging a rechargeable power source of an implantable medical device (IMD). In some cases, the transmitter may include an output driver that may drive a transmit coil such that near-field energy is transmitted to the IMD at a determined frequency. In some cases, the IMD may include a receiving coil that may capture the near-field energy and then convert the near-field energy into electrical energy that may be used to recharge the rechargeable power source. Since the rechargeable power source does not have to maintain sufficient energy stores in a single charge for the entire expected life of the IMD, the power source itself and thus the IMD may be made smaller while still meeting device longevity requirements.

摘要： 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.

摘要： A leadless cardiac pacemaker (LCP) is configured to sense cardiac activity and to pace a patient's heart and is disposable within a ventricle of the patient's heart. The LCP may include a housing, a first electrode and a second electrode that are secured relative to the housing and are spaced apart. A controller is disposed within the housing and is operably coupled to the first electrode and the second electrode such that the controller is capable of receiving, via the first electrode and the second electrode, electrical cardiac signals of the heart. The LCP may include a pressure sensor and/or an accelerometer. The controller may determine an atrial contraction timing fiducial based at least in part upon two or more of a signal from the pressure sensor, a signal from the accelerometer representing, and an electrical cardiac signal.

摘要： An Implantable Medical Device (IMD) configured to be implantable in a ventricle of a patient's heart may include a housing, a first electrode secured relative to the housing, a second electrode secured relative to the housing, the second electrode spaced from the first electrode, and circuitry in the housing operatively coupled to the first electrode and the second electrode. The circuitry may be configured to identify a measure of impedance between the first electrode and the second electrode at each of a plurality of times during a cardiac cycle. Each measure of impedance may represent a measure of volume of the ventricle in which the IMD is implanted. In some cases, the circuitry may generate a pacing pulse, the timing of which is based at least in part on the measure of volume of the ventricle at two or more of the plurality of times during the cardiac cycle.
