Abstract
A body implantable lead and a stiffening stylet with a flexible tip for imparting rigidity to the lead to facilitate attachment of the lead to an internal body organ and for transmitting torque to the distal end of the lead. A flexible tip stiffening stylet is provided for insertion into a lumen in the lead extending from a pin at its proximal end along the length of the lead conductor to the electrode. A portion of the stylet wire inserted in the lumen has a thinner diameter over a portion of its length near the distal end to permit smooth transmission of torque by rotation of the stylet wire even in applications where the lead and stylet are tightly bent in the vicinity of the thinned portion of the lead.
