PACING SYSTEM FOR USE DURING CARDIAC CATHETERIZATION OR SURGERY
First Claim
1. A pacing system for use during a percutaneous transluminal vascular intervention (PTVI) procedure, the system comprising:
- an intravascular ultrasound (IVUS) catheter being a PTVI device including a proximal end portion, a distal end portion, and an elongate shaft connected between the proximal end portion and the distal end portion, the distal end portion configured for intravascular placement and including;
an ultrasonic transducer configured to transmit an ultrasound signal and receive an image signal related to the transmitted ultrasound signal; and
a first pacing electrode configured to deliver pacing pulses.

Abstract
Cardioprotective pacing is applied to prevent and/or reduce cardiac injury associated with cardiac catheterization or surgery. Pacing pulses are generated from a pacemaker and delivered through one or more pacing electrodes incorporated onto one or more devices used in the cardiac catheterization or surgery. The pacemaker controls the delivery of the pacing pulses by executing a cardioprotective pacing protocol. In one embodiment, the one or more pacing electrodes are incorporated onto an intravascular ultrasound (IVUS) catheter. In another embodiment, the one or more pacing electrodes are incorporated onto one or more cardiac surgical instruments such as a heart stabilizer and a sternal retractor.
