METHOD AND APPARATUS FOR PACING AND INTERMITTENT ISCHEMIA
First Claim
1. A system for delivering cardiac protection therapies to a heart via a blood vessel, comprising:
- a catheter having at least one balloon along its length, the balloon adapted to be placed in the blood vessel to at least partially occlude the blood vessel;
at least one pacing electrode along the length of the catheter;
at least one hemodynamic sensor near a tip of the catheter; and
a controller connected to the catheter and adapted to sense a hemodynamic parameter being a measure of hemodynamic performance using the hemodynamic sensor, and adapted to control inflation and deflation of the balloon to provide intermittent ischemia, and further adapted to control pulses to the at least one pacing electrode to provide cardiac protection pacing therapy (CPPT).

Abstract
A system delivers multiple enhanced therapies to limit myocardial damage post-revascularization. The system includes a catheter that incorporates features for delivering cardiac protection pacing therapy (CPPT) and intermittent ischemia therapy. In one embodiment, a method for delivering cardiac protection therapies to a heart is provided. One or more catheters are provided having a balloon, at least one pacing electrode and at least one hemodynamic sensor. Cardiac protection pacing therapy (CPPT) and intermittent ischemia therapy are concurrently delivered using the one or more catheters. The pacing and ischemia are adapted to protect the heart from ischemic and reperfusion injuries. The delivery of the CPPT and the intermittent ischemia are controlled using a closed-loop system monitoring a signal sensed by the at least one hemodynamic sensor.
