ABSTRACT:
A novel cardiac lead assembly is described which includes an elongatable coil spring which serves to connect a screw-in electrode tip with a connector. A flange is affixed to the electrode tip and the lead is positioned inside a tubular lead insertion device. In order to install this lead in a heart, the coil spring is stretched while using the installation device to position the flange precisely with respect to the heart. Once proper position of the electrode tip has been assured, the coil spring is released abruptly such that the potential energy of the spring propels the electrode tip against the heart with sufficient momentum to embed the electrode tip in the heart in a single motion. Preferably, the spring also imparts an angular momentum to the electrode tip which tends to screw the electrode tip into the heart. The illustrated embodiments of the lead include a plurality of spirally oriented elongated prongs which serve to engage the surface of the heart mechanically. Also, a braided wire sheath is disclosed which is rigidly attached to the flange at its distal end and serves to transmit torques down the length of the lead efficiently for screwing the lead into or out of the heart as desired.
