5. Caution: To prevent damage to the DirectVision® Guide and
camera handpiece, always handle with care. Do not drop,
crush, cut, or bend any portion of the visual guide beyond
a 2” radius. Although the visual guide is flexible, bending
beyond the specified radius could cause breakage in the
fiber optic bundle, which reduces its useful life. Kinking the
visual guide could break the entire fiber optic bundle which
can render it non-operational.
6. Caution: Do not expose the DirectVision® System to
excessive heat which can cause damage.
7. Caution: Never place heavy objects on the DirectVision®
System.

Product Description
DirectVision® product line consists of:
•DirectVision® System
– Camera Handpiece
– Camera Control Unit (CCU)
– Monitor Display
– Cart
•DirectVision® Guide
•DirectVision® Catheter
Camera Handpiece
The camera handpiece contains the camera, optics to focus the
video image and an LED white light source. Camera operation is
dependent on receiving power and input video control signals
from the CCU. It uses the input control signals to produce
streaming video output .
The camera handpiece has a locking swing arm to securely couple
the camera handpiece to the DirectVision® Guide. The body of
the camera handpiece has a Focus Ring, which provides focus for
the video image.

The camera handpiece provides two interfaces:
•Visual Guide
•CCU
Visual Guide Interface
The camera handpiece provides alignment and a locking
mechanism for the camera handpiece- visual guide interface.
When the camera handpiece is not attached to the visual guide, a
protection cap is locked into place.

Camera Control Unit Interface
A shielded cable attached to the camera connector plug provides
the wired electrical interface between the Camera Control Unit
(CCU) and the camera handpiece. When plugging the camera
connector into the CCU, use the red dots on the camera connector
and CCU receptacle to align the recessed connector pins for
proper insertion.
Caution: Be careful how you align the Camera Handpiece Plug into
the CCU Connector Receptacle. Failure to align pins with the
corresponding pin hole could cause damage to the pins.

Storage during Transportation
When the camera handpiece is not in use,
1. The wired attached Plug Cap is locked to the Camera
Handpiece Plug. The Plug Cap protects the receded gold
connector pins.
2. Protection cap is locked into place. The cap protects the
front glass of the LED light source and camera from
accumulating dust. It also protects the outside rim of the
lock mechanism of the handpiece from damage.
3. The handpiece is stored in the cart storage drawer.
