Abstract: The disclosure describes examples of antennas used for communication with an implantable medical device (IMD). As one example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing, and a planar antenna, having a curved structure, that is stacked on an external side of the housing and coupled to the communication circuitry. As another example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing and an antenna having a curved structure formed on an external side of the housing and coupled to the communication circuitry. A resonant frequency of the antenna is based on a dielectric constant of tissue surrounding the antenna when the IMD is implanted, and a current distribution of the antenna is in-phase in opposite sides of the antenna.

Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

Abstract: An integrated valve prosthesis includes an anchor stent, a tether component, and a valve component. The anchor stent includes a self-expanding tubular frame member configured to be deployed in the annulus of an aortic valve or the aorta. The valve component includes a valve frame and a prosthetic valve coupled to the valve frame, and is configured to be deployed within the anchor stent. The tether component includes a first end coupled to the anchor stent and a second end coupled to the valve frame. In the delivery configuration, the tether component extends in a first direction from the anchor stent to the valve component, and in the deployed configuration, the tether component extends in a second direction from the anchor stent to the valve component. The second direction is generally opposite the first direction. The tether component may set the location of the valve component relative to the anchor stent.

Abstract: A medical device is configured to sense event signals from a cardiac electrical signal and determine maximum amplitudes of cardiac electrical signal segments associated with sensed event signals. The medical device is configured to determine at least one tachyarrhythmia metric based on at least a greatest one of the determined maximum amplitudes. The medical device may determine when the at least one tachyarrhythmia metric does not meet true tachyarrhythmia evidence and, in response, determine when the maximum amplitudes meet suspected noise criteria. The medical device may withhold a tachyarrhythmia detection and tachyarrhythmia therapy when suspected noise criteria are met.

Abstract: Distal connector assemblies that are on the distal end of medical lead extensions provide increased rigidity by including a rigid holder that contains the electrical connectors. The electrical connectors are separated within the rigid holder by insulative spacers that may be individual items or may be formed from a compliant carrier that the electrical connectors may reside within where the carrier is positioned within the rigid holder. The rigid holder may also contain a set screw block defining set screw bore or the rigid holder may include an integral portion that defines a set screw bore. The integral portion may include a slot to allow a molding pin loaded with the electrical connectors and other components to be dropped into a cavity of the rigid holder. An overmold may be present to surround the rigid body containing the electrical connectors and insulative spacers.

Abstract: Implantable medical devices include elongated conductor bodies and related features including an attachment to the medical device at one end and a connector that receives a medical lead at the other end. The connector may have various features such as a modular design whereby the connector is constructed from a series of stacked contact modules. Other features of the connector include electrical contacts that are relatively thin conductors or the order of 0.040 inches or less and that may include radial protrusions to establish contact with the electrical connectors of the lead. Furthermore, electrical contacts may be mounted within the connector in a floating manner so that radial movement of the electrical contact may occur during lead insertion. Additional features include a feedthrough where conductors exposed beyond a housing of the implantable medical device make direct electrical connection to conductors present within the elongated body.

Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: Techniques for transmitting diagnostic information stored in an implantable medical device (IMD) based on patient hospitalization are described. For example, the IMD may transmit higher resolution diagnostic information to a clinician and/or an external device during a hospitalization period to aid the clinician in evaluating heart failure treatment and when discharge is proper. This higher resolution diagnostic information may include one or more patient metrics automatically generated and transmitted by the IMD at least once every two hours. During a post-hospitalization period, the IMD may transmit lower resolution diagnostic information to a clinician that indicates a risk level of re-hospitalization. The lower resolution diagnostic information may include the risk level and/or patient metrics once a day, for example. In this manner, the IMD transmitted diagnostic information may be tailored to the specific heart failure monitoring needed by the patient.
