Abstract
A leadless intra-cardiac medical device (LIMD) configured to be implanted entirely within a heart of a patient includes a housing configured to be securely attached to an interior wall portion of a chamber of the heart, and a stabilizing intra-cardiac (IC) device extension connected to the housing. The stabilizing IC device extension may include a stabilizer arm, and/or an appendage arm, or an elongated body or a loop member configured to be passively secured within the heart.
Claims9
A leadless intra-cardiac medical device configured to be implanted entirely within a heart of a patient, the device comprising:
- a housing configured to be securely attached to an interior wall portion of a chamber of the heart, the housing having a proximal end and a distal end, and the housing hermetically enclosing electronics, a controller, and a battery;
- a securing device extending from the proximal end of the housing, the securing device configured to secure the housing to cardiac tissue;
- an appendage arm extending from the distal end of the housing, the appendage arm having a proximal end directly connected to the distal end of the housing, and the appendage arm having a distal end upon which an electrode is disposed;
- a 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.
