Claims
- 1. 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.
- 2. The IMD of claim 1 wherein the wings form substantially curvilinear edges.
- 3. The IMD of claim 1 wherein said multi-vector relations include a rule-based software program implemented to select from said multi-vector relations at least one vector relation.
- 4. The IMD of claim 1, wherein the bend is located in proximity to a mid-point of the center-line axis of the body.
- 5. The IMD of claim 1, wherein the first electrode and the second electrode are positioned on a first side of the center-line axis and the third electrode is positioned on a second side of the center-line axis.
- 6. The IMD of claim 1, wherein the body further includes a side spanning the width of the body and at least one of the plurality of electrodes is positioned on the side.
- 7. The IMD of claim 1, wherein the body further includes a side spanning the thickness of the body and at least one of the plurality of electrodes is positioned on the side.
- 8. The IMD of claim 1, wherein one or both of the first wing and the second wing includes at least one suture hole.
- 9. The IMD of claim 1, wherein the plurality of electrodes includes only three electrodes.
