Abstract:
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 a center-line axis, the body including a bend, a first wing extending from a first side of the bend and a second wing extending from a second side of the bend; and a plurality of electrodes coupled to said geometric body such that a first electrode of the plurality is positioned on the first wing, a second electrode of the plurality is positioned on the second wing and a third electrode of the plurality is positioned proximate to the bend; wherein a line extending from the first electrode to the third electrode forms an angle with a line extending from the second electrode to the third electrode, the angle being between and including 45 degrees and 100 degrees; and whereby said electrodes form multi-vector relations and said geometric body is adapted for ease of subcutaneous insertion in a patient's body and for positional stability within the patient's body to thereby sense physiological signals via said electrodes.
