Abstract:
1. A method of implanting a leadless intra-cardiac medical device (LIMD) entirely within a heart of a patient, wherein the device includes a housing and a stabilizing intra-cardiac device extension connected to the housing, the method comprising: navigating the device into the heart with an introducer assembly, the extension held in a collapsed installation shape within the introducer assembly; positioning the introducer assembly so that the housing is proximate an implant site within the heart, the housing hermetically enclosing electronics, a controller, and a battery; securely anchoring the housing to the implant site; separating the introducer assembly and the device thereby allowing the extension to expand to a deployed implanted shape; and securing the extension within a portion of the heart so that the device is entirely within the heart of the patient, the extension having an appendage arm and a stabilizer arm, the appendage arm extending from a distal end of the housing, the appendage arm having a proximal end directly connected to the distal end of the housing, the appendage arm having a distal end upon which an electrode is disposed, the stabilizer arm extending from the distal end of the housing, the stabilizer arm having a proximal end directly connected to the distal end of the housing, and the stabilizer arm having a distal end upon which a pusher cup is disposed.
