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.

Accessories Intended for Use in Combination with the Device:

Name of Accessory Description of Accessory
Guidewire Acts as a path for other components.
Guidewire Advancer Helps guidewire introduction.
Introducer Needle Placed into the target vein to gain access.
Scalpel A cutting device.
Dilator Used to make the opening of a vessel larger.
End Cap To keep the catheter clean between treatments.
Syringe Helps get blood return once the needle punctures the vein.

4. Risks and Warnings

If you think something is wrong with how you feel after using the device or you're worried about any problems, talk to your healthcare professional. Remember, this information is not meant to take the place of talking to your doctor if you need to.

How Potential Risks Have Been Controlled or Managed

There have been 208,951 devices sold since January 2019. There are side effects and risks associated with the device. 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. The most common problem is getting an infection. Infections can happen when someone has surgery or stays in the hospital. Infections are not always caused by use of the device. The below tables includes events that can happen when the tube is put in, used, or taken out. Not all device problems are reported.

    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)

    There were no recalls for the device between 01 January 2023 to 31 December 2023.

    5. 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.

    Safety

    There is sufficient data to prove conformity to the applicable requirements. The device is safe and performs as intended and claimed by Medcomp. The device is state of the art for allowing short-term vascular access for hemodialysis in adult patients. Medcomp has reviewed:

  • Post-Market Data
  • Medcomp Information Materials
  • Risk Management Documentation
  • The risks are appropriately displayed and consistent with the state of the art. The risks associated with the device product family are acceptable when weighed against the benefits. There were 94 complaints for 208,951 units sold from 01 January 2019 to 31 December 2023. The complaint rate is 0.045%.

    6. Possible Therapeutic Alternatives

    When considering alternative treatments, it is recommended to contact your healthcare professional who can consider your individual situation.
