A temporary cardiac electrical stimulating lead is disclosed having a stimulating electrode mounted in or on an electrode mounting pad disposed at a distal end of the lead, the pad having a biodegradable adhesive disposed thereon and/or therewithin. The adhesive, and preferably also the electrode mounting pad, are capable of biodegradably dissolving over time in human body fluids. The adhesive permits the electrode mounting pad to be attached to a patient's epicardium without the use of sutures, or with fewer sutures than have heretofore been required to suitably affix an electrode mounting pad to a patient's heart. In a preferred embodiment, when the lead body is pulled away from the electrode mounting pad and removed from a patient, any portion of the electrode mounting pad and the adhesive remaining within the patient dissolves over time and disappears.

1. A temporary medical electrical lead for pacing or defibrillating a heart of a patient, the lead having distal and proximal ends, comprising:(a) a lead body having proximal and distal ends, comprising: (i) at least one electrical conductor having proximal and distal ends; (ii) an insulative sheath formed of biocompatible and electrically insulative material, the sheath extending over and covering at least portions of the at least one electrical conductor; (b) an electrical connector assembly attached to the proximal end of the at least one electrical conductor for attachment to a device capable of providing pacing or defibrillation pulses therethrough; (c) an electrode mounting pad disposed near the distal end of the lead body, at least one of the distal end of the at least one electrical conductor and an electrode member secured to the distal end of the at least one electrical conductor being attached to or integrated into the electrode mounting pad, the electrode mounting pad having a lower surface for placement against the patient's myocardium, the electrode mounting pad comprising a biodegradable, biocompatible material soluble in human body fluids, and (d) a temporary biodegradable adhesive disposed on at least portions of the lower surface of the electrode mounting pad, the adhesive being suitable for attaching the at least portions of the lower surface to the patient's myocardium when the at least portions of the lower surface containing the adhesive are pressed against the patient's myocardium.
