Abstract
The present invention includes within its scope a low-cost temporary lead for pacing, sensing, monitoring, or defibrillating at least a portion of a human or animal organ, and methods for implanting and making same. The lead has at least two electrodes and distal and proximal ends, and a novel weakened zone disposed between the blunt end of a needle and at least two electrical connectors attached to the proximal end of the lead body. The novel weakened zone permits the needle to be separated from the connectors by application of a sufficiently large bending moment or pulling force thereto. Following separation of the connectors from the needle, the connectors may be attached directly and quickly to an external electrical apparatus.
