Abstract
An apparatus for delivering a prosthetic heart valve includes a steerable guide catheter, a balloon catheter, and a flex indicator. The guide catheter has a handle and a guide tube extending from the handle. The guide tube has a distal end portion comprising a steerable section. The guide catheter further includes an adjustment mechanism on the handle and a pull wire connecting the adjustment mechanism to the steerable section for changing flexion of the steerable section. The balloon catheter includes a shaft extending coaxially through the guide tube. The shaft includes a proximal end portion and a distal end portion. The balloon catheter further includes a balloon mounted on the distal end portion of the shaft. The flex indicator moves relative to the handle upon adjustment of the adjustment mechanism. The handle includes visual indicia adjacent the flex indicator to provide visual indication of the flexion of the steerable section.
