    摘要: A leadless implantable medical device (LIMD) includes a housing formed from a battery and an end cap. A proximal end of the end cap forms an LIMD proximal end and a distal end of the battery case forms an LIMD distal end. A non-conductive coupler mechanically secures a terminal end of the battery case to a mating end of the end cap, while maintaining the battery case and end cap electrically separated. A first electrode projects from the proximal end of the end cap. An intra-cardiac (IC) device extension projects from the distal end of the battery case. The extension includes a second electrode that is electrically connected to the battery case. The second electrode is located remote from the LIMD distal end. An electronics module is located within an internal cavity of the end cap and communicates with the first and second electrodes.

    摘要: A leadless intra-cardiac medical device (LIMD) includes an electrode assembly configured to be anchored within a first wall portion of a first chamber of a heart. The electrode assembly includes an electrode main body having a first securing helix, an electrode wire segment extending from the body, and a first segment-terminating contact positioned on the electrode wire segment. The device further includes a housing assembly configured to be anchored within a second wall portion of a second chamber of the heart. The housing assembly includes a body having a second securing helix, a housing wire segment extending from the body, and a second segment-terminating contact positioned on the housing wire segment. The device also includes a connector block that electrically connects the electrode wire segment to the housing wire segment by retaining the first and second segment-terminating contacts.

    摘要: A leadless intra-cardiac medical device (LIMD) includes multiple electrodes that allow for stimulation and sensing of the right ventricle (RV) and sensing of the right atrium (RA), even though it is entirely located in the RV. The LIMD includes a housing having a proximal end configured to engage local tissue in the local chamber and electrodes located at multiple locations along the housing. Sensing circuitry is configured to define a far field (FF) channel between a first combination of the electrodes to sense FF signals occurring in the adjacent chamber. The sensing circuitry is configured to define a near field (NF) channel between a second combination of the electrodes to sense NF signals occurring in the local chamber. A controller is configured to analyze the NF and FF signals to determine whether the NF and FF signals collectively indicate that a validated event of interest occurred in the adjacent chamber.

    摘要: A leadless intra-cardiac medical device is configured to be implanted entirely within a heart of a patient. The device includes an intra-cardiac extension and a housing. The intra-cardiac extension includes a loop body having at least one loop segment retaining at least one coil group that is configured to one or both of receive and transmit radio frequency (RF) energy, wherein the loop body is configured to extend into a first chamber of the heart. The housing is in electrical communication within the loop body, and includes a transceiver, control logic and an energy source. The housing is configured to be securely attached to an interior wall portion of a second chamber of the heart, wherein the transceiver is configured to communicate with an external device through the RF energy.
