INSTRUCTIONS FOR USE
INDICATIONS FOR USE
Retro* Silicone Twin Lumen Chronic Hemodialysis Catheter with Separated Tips is designed
for chronic hemodialysis and apheresis. It is a radiopaque silicone catheter designed for
percutaneous insertion or insertion via a cutdown. Catheters longer than 40 cm are intended
for femoral vein insertion.
CATHETER PLACEMENT
The catheter can be placed percutaneously using a modified “Seldinger Technique” or open
venotomy.
Fluoroscopic or ultrasonic guidance is recommended to ensure proper tip orientation and
placement within the right atrium.
CONTRAINDICATIONS
This catheter is intended for long-term vascular access only and should not be used for any
purpose other than that indicated in these instructions.
DESCRIPTION
The Retro* Twin Lumen Chronic Hemodialysis Catheter with Separated Tips is constructed of
radiopaque medical grade silicone. Its oval shape and silicone material composition provide
improved flexibility and kink resistance.
To reduce recirculation during hemodialysis, the arterial lumen of the catheter is shorter than
the venous lumen at the catheter’s distal end. The catheter has a felt cuff and has separate
color-coded extension adapters.
The proximal ends of the catheter are tunneled retrograde to the exit site after the tips have
been positioned. This design allows the catheter tips to be precisely positioned. The two
proximal ends of the catheter, namely, arterial and venous, are connected to the colorcoded
extension adapters. Each extension adapter has a compression sleeve, compression cap,
clamp and luer.
