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. At the proximal end of the stylet, a guide and rotation control device is provided to aid in insertion of the lead and stylet and to facilitate rotation of the stylet to permanently attach the electrode at the distal end to a body organ through endothelial tissue.
