1. A cardiac pacing system for use during revascularization of a blood vessel, the system comprising:
- a percutaneous transluminal vascular intervention (PTVI) device including;
a proximal end portion;
a distal end portion configured to be placed in the blood vessel;
an elongate shaft coupled between the proximal end portion and the distal end portion; and
a plurality of pacing electrodes; and
a pacemaker including;
a flexible circuit substrate affixed to the PTVI device; and
a flexible pacemaker circuit including an electronic circuit built on the flexible circuit substrate, the flexible pacemaker circuit configured to deliver cardiac pacing pulses through the plurality of pacing electrodes.

Abstract
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 flexible pacemaker circuit integrated with a percutaneous transluminal vascular intervention (PTVI) device and delivered through pacing electrodes incorporated onto the PTVI device during the revascularization procedure.
