1. A device for implanting a prosthetic heart valve at an implantation site, the device including:
- a shaft having a distal end adapted to couple to the prosthetic heart valve and maintain the valve in a collapsed configuration;
an illuminator selectively adjustable to provide a variable lighting field, the illuminator coupled at or near the distal end of the shaft;
an optical fiber extending through at least a portion of the shaft, the optical fiber having a proximal end extending from a proximal end of the shaft and a distal end coupled to the illuminator, the optical fiber is adapted to transmit the lighting field from the illuminator to the distal end of the shaft; and
an actuator coupled to the illuminator and adapted to effect a change to the variable lighting field.

Abstract
A device for locating an operational unit within a patient'"'"'s body within the framework of a minimally-invasive surgery intervention includes a shaft having a distal end carrying an operational unit. The device includes an illuminator located at the distal end of the shaft. The illuminator is selectively adjustable to provide a selectively variable lighting field in correspondence with the operational unit. The device may be, for example, a delivery system for a heart valve or a balloon device for post-dilation of such a heart valve once implanted.
