Classification: CPC A | IPC A

Claim 0:
1. An implantable medical lead comprising:
a distal portion that defines a serpentine shape and extends proximally from a distal tip of the implantable medical lead;
a proximal portion configured to be coupled to an implantable medical device;
at least one visible indicator located between the distal portion and the proximal portion at a discrete radial position and a discrete longitudinal position between 18 and 25 centimeters from the distal tip along a longitudinal axis of the implantable medical lead, wherein the at least one visible indicator is configured to indicate a radial orientation of the distal portion of the implantable medical lead and indicate a depth of the distal portion of the implantable medical lead in a patient when the distal portion is adjacent a target site in the patient while the at least one visible indicator is external to the patient;
a first pacing and/or sensing electrode that defines a proximal edge between 10 and 12 centimeters distal of the visible indicator along the longitudinal axis;
a first defibrillation electrode that defines a proximal edge between 11 and 13 centimeters distal of the at least one visible indicator along the longitudinal axis and is configured to curve toward a right side of a heart of the patient upon implantation;
a second pacing and/or sensing electrode that defines a proximal edge between 14.5 and 16.5 centimeters distal of the at least one visible indicator along the longitudinal axis; and
a second defibrillation electrode that defines a proximal edge between 15 and 17 centimeters distal of the at least one visible indicator along the longitudinal axis and is configured to curve toward the right side of the heart of the patient upon implantation; and
an introducer sheath including a distal portion configured to be inserted into the patient to a targeted depth and an entry port at a proximal portion of the introducer sheath, wherein the distal portion of the implantable medical lead is configured to be inserted into the entry port of the introducer sheath and moved towards the distal portion of the introducer sheath, and wherein the at least one visible indicator is configured to indicate the radial orientation of the distal portion of the implantable medical lead within the introducer sheath and indicate the depth of the distal portion of the implantable medical lead within the introducer sheath; wherein the proximal portion of the introducer sheath includes a window adjacent the entry port of the introducer sheath and configured to be located outside the patient when the distal portion of the introducer sheath is at the targeted depth.
