Abstract
A body implantable lead system includes an over-the-wire lead with a longitudinally extending lumen. A hollow stylet having an outer peripheral surface is introduced into the lumen and an annular resilient blood seal within the lumen may be sealingly positioned between the outer peripheral surface of the stylet and the lead to prevent flow of blood beyond the blood seal and into the lumen in a proximal direction. A guidewire is slidably received within the hollow stylet and includes a tip end which may project through the passage at the distal end of the lead such that relative movement of the guidewire and stylet within the lead is enabled while avoiding friction between the blood seal and the guidewire. Either the guidewire or the stylet may be preshaped for proper placement of the lead for engagement with the body tissue and surrounded by a semi-rigid retractable sheath.
