Patent ID: 8457738

Claim:
A percutaneous transluminal vascular intervention (PTVI) device assembly for use during revascularization of a blood vessel, the PTVI device assembly comprising: a plurality of pacing leads each including a pacing lead distal end portion and one or more pacing electrodes incorporated onto the pacing lead distal end portion; a catheter including: a catheter proximal end portion; a catheter distal end portion configured to be placed in the blood vessel and including a catheter distal tip; an elongate catheter shaft coupled between the catheter proximal end portion and the catheter distal end portion; one or more entry ports at the catheter proximal end portion; a plurality of exit ports including at least one exit port at the catheter distal tip; and a further pacing electrode at the catheter distal tip, the catheter configured to allow the pacing lead distal end portion of each pacing lead of the plurality of pacing leads to enter an entry port of the one or more entry ports and exit from an exit port of the plurality of exit ports; and a pacemaker configured to be connected to the pacing lead distal end portions of the plurality of pacing leads, the pacemaker including: a pacing output circuit configured to deliver pacing pulses through the one or more pacing electrodes and the further pacing electrode; and a control circuit coupled to the pacing output circuit and configured to execute a cardioprotective pacing protocol specifying one or more cardiac protection pacing sequences each including alternating pacing and non-pacing periods, the pacing periods each having a pacing duration during which a plurality of the pacing pulses is timed to be delivered according to a stress augmentation pacing mode to augment myocardial mechanical stress to a level effecting cardioprotection against myocardial injury, the non-pacing periods each having a non-pacing duration during which none of the pacing pulses is timed to be delivered.
