Claim:
1. An apparatus for subcutaneous lead guidance comprising: a flexible guide strap having a first end and a second end, the guide strap adapted to be attachable on a patient's skin to extend along a planned tunneling path between the first end positioned adjacent an incision and the second end positioned adjacent a target site; a shielded flexible circuit and a plurality of induction coils attached to the guide strap to define the planned tunneling path from the incision to the target site; a tunneling tool having a distal portion with a leading end and at least one position sensor on the distal portion; and a feedback device coupled to the tunneling tool and the flexible circuit and configured to generate a first feedback signal as the leading end approaches the target site within the planned tunneling path and a second feedback signal different than the first feedback signal if the leading end veers off the planned tunneling path.
