  • Patent number: 9463315
    Abstract: A method of implanting a leadless intra-cardiac medical device. An introducer assembly is introduced into one of an inferior vena cava or a superior vena cava of a heart and maneuvered into a first chamber of the heart. A housing is pushed out of a sheath of the introducer toward a first implant location within the first chamber, and the housing is anchored to the first implant location. The sheath is moved away from the anchored housing, and an electrode is urged to a distal end of the sheath due to the pushing, anchoring, and moving. The sheath is maneuvered to a second chamber of the heart, and the electrode is forced into a second implant location with the second chamber. The electrode is anchored to the second implant location. The sheath is moved away from the electrode after the anchoring, and the sheath is removed from the heart.

    Abstract: Systems and methods are provided for managing tiered tachycardia therapy. The systems and methods measure a cardiac feature of interest (FOI) from a cardiac electrical signal of a heart sensed from at least one electrode of a leadless cardiac pacemaker (LPM). The systems and methods detect when the cardiac FOI satisfies an arrhythmia criteria, and deliver anti-tachycardia pacing (ATP) to the heart using the at least one electrode of the LPM when the cardiac FOI satisfies the arrhythmia criteria. The systems and methods deliver a series of arrhythmia emulating (AE) pulses configured to emulate a cardiac arrhythmia to the heart using the at least one electrode of the LPM if the FOI in cardiac signals measured subsequent to the delivery of the ATP therapy satisfy the arrhythmia criteria.

The bioelectric battery may also have a membrane surrounding the cathode to reduce tissue encapsulation. Alternatively, an anode electrode, a cathode electrode surrounding the cathode electrode, a permeable membrane surrounding the cathode electrode. An electrolyte is disposed within the permeable membrane and a mesh surrounds the permeable membrane.
