Abstract
A medical device for multi-vector sensing of cardiac depolarization signals is disclosed. Specialized algorithm is implemented to enhance multi-vector electrode sensing. Further a geometric shape is optimized to enable space-volume efficiencies for deployment and navigation of the medical device for implant in a patient.
Claims9
An implantable medical device (IMD) including a plurality of sensing electrodes configured for multi-vector sensing forming an insertable loop recorder (ILR) in combination, the IMD comprising:
- a geometric body having a thickness smaller than its width and wherein said width is smaller than a length defined along an axial-center;
- a plurality of electrodes distributed at location within the perimeter of said geometric body;
- and
- said geometric body being adapted for ease of subcutaneous deployment in a patient's body to thereby sense physiological signals via said electrodes.
