Pacing catheter with expandable distal end
Cardioprotective pacing is applied to prevent and/or reduce cardiac injury associated with myocardial infarction (MI) and revascularization procedure. Pacing pulses are generated from a pacemaker and delivered through one or more pacing electrodes incorporated onto one or more percutaneous transluminal vascular intervention (PTVI) devices during the revascularization procedure. In one embodiment, a PTVI device includes an expandable distal end to provide a stable electrical contact between a pacing electrode and the vascular wall of a blood vessel when the distal end is placed in the blood vessel.
