Information on Medicinal Substances in the Device: N/A

How the Device Achieves its Intended Mode of Action: Hemodialysis tubes provide access through the vein or artery. The tube is thin and flexible and goes into a big vein near the center of the body. There are two openings in the tube. One opening takes out the blood and sends it to a machine that cleans it. The other opening puts the clean blood back into the body. This tube is used when someone needs to have their blood cleaned right away, and they can't use a different kind of tube. This tube is only used for a short time.

Cleaning (Sterilization) Information: Contents are clean and will not cause fever in unopened, undamaged package. Sterilized by Ethylene Oxide.

These include: • Infection Bleeding Tube Removal Tube Replacement These risks are reduced to an acceptable level. The labeling describes the risks. The benefit of the device is access for hemodialysis when alternatives are not suitable. These benefits outweigh the risks.

Remaining Risks and Undesirable Effects

The Duo-Flow® catheter is associated with risks. These include: • Procedural Delays Blood clots in veins (Thrombosis) Infections Punctures in organs (Perforations) Air bubbles in veins (Embolism) Heart problems (Cardiac Event) Feeling unhappy with the procedure (Dissatisfaction) The risks of using the Medcomp device are similar to other dialysis tubes.

Warnings and Precautions

The below are warnings, precautions, or measures to be taken by patient: • To keep germs away from the catheter, wear a mask over your nose and mouth every time the catheter is used. Keep the catheter dressing clean and dry. The dressing should be changed by a medical professional at each dialysis session. Avoid getting the catheter or catheter site wet. Moisture near the catheter site can cause infection. Ask the doctor to explain the signs and symptoms of catheter infection. Never remove the cap at the end of the catheter. The cap and clamps of the catheter must be kept closed when not being used for dialysis.

Summary of Any Field Safety Correction Action (FSCA)

Summary of Clinical Evaluation and Post-Market Clinical Follow-Up

Clinical Background of Device

The Duo-Flow® catheter has been available since 1984. The CE Mark was received in March 2001. US FDA clearance was in July 1984. All models included are planned for distribution in the European Union.

Clinical Evidence for CE-Marking

The clinical literature review identified 13 articles relating to the safety and/or performance of the subject device when used as intended. These articles included approximately 505 cases. Three patient level data activities received information on 29 catheters. Findings from the clinical literature and data activities support the performance of the subject device. All data on the Duo-flow® catheter has been evaluated. When you use the device as intended, the good things it does are more than the bad things it might cause. This device helps people who have kidney problems get hemodialysis when other treatments are not right for them.
