Information on Medicinal Substances in the Device: N/A

How the Device Achieves its Intended Mode of Action: Hemodialysis catheters are centrally placed access tubes. A typical hemodialysis catheter uses a thin, flexible tube. The tube has two openings. The tube goes into a large vein. The vein is usually the internal jugular vein. Blood withdraws through one lumen of the catheter. The blood flows to the dialysis machine through a separate tubing set. The blood is then processed and filtered. The blood returns to the patient through the second lumen. This device is used when dialysis must start at once. Patients may not have a functioning AV fistula or graft. Catheter hemodialysis normally happens on a short-term basis.

Sterilization Information: Contents sterile and non-pyrogenic in unopened, undamaged package. Sterilized by Ethylene Oxide.

4. Risks and Warnings

Residual Risks and Undesirable Effects: All surgical procedures carry risk. Medcomp® has implemented risk management processes to proactively find and mitigate these risks as far as possible without adversely affecting the benefit-risk profile of the device. After mitigation, residual risks and the possibility of adverse events from use of this product remain. Medcomp® has determined that all residual risks are acceptable when considered with respect to the expected clinical benefits of the Duo-Flow® III Catheter and the benefits of other similar hemodialysis devices.

Warnings and Precautions:

Warnings listed for the Duo-Flow® III Catheter are as follows:

• Do not insert catheter in thrombosed vessels.
• Do not advance the guidewire or catheter if unusual resistance is encountered.
• Do not insert or withdraw the guidewire forcibly from any component. If the guidewire becomes damaged, guidewire and any associated componentry must be removed together.
• Do not resterilize the catheter or accessories by any method.
• Contents sterile and non-pyrogenic in unopened, undamaged package. STERILIZED BY ETHYLENE OXIDE
• Do not re-use catheter or accessories as there may be a failure to adequately clean and decontaminate the device which may lead to contamination, catheter degradation, device fatigue, or endotoxin reaction.
• Do not use catheter or accessories if package is opened or damaged.
• Do not use catheter or accessories if any sign of product damage is visible or the use-by date has passed.
• Do not use sharp instruments near the extension tubing or catheter lumen.
• Do not use scissors to remove dressing. Precautions listed for Duo-Flow® III Catheter are as follows:
• Examine catheter lumen and extensions before and after each treatment for damage.
• To prevent accidents, ensure the security of all caps and bloodline connections prior to and
• between treatments.
• Use only Luer Lock (threaded) Connectors with this catheter.
• In the rare event that a hub or connector separates from any component during insertion or use, take all necessary steps and precautions to prevent blood loss or air embolism and remove the catheter.
• Before attempting catheter insertion, ensure that you are familiar with the potential complications and their emergency treatment should any of them occur.
• Repeated overtightening of bloodlines, syringes, and caps will reduce connector life and could lead to potential connector failure.
• The catheter will be damaged if clamps other than what is provided with this kit are used.
• Avoid clamping near the Luer Lock and hub of the catheter. Clamping of the tubing repeatedly in the same location may weaken tubing.

Other Relevant Aspects of Safety: For a period of 01 January 2019 to 31 December 2023 there were 4 complaints for 22,186 units sold, giving an overall complaint rate of 0.018%. There were no death-related events. No events resulted in recalls during the review period.

5. Summary of Clinical Evaluation and Post-Market Clinical Follow-Up (PMCF)

Summary of Clinical Data Related to Subject Device

Clinical performance was measured using parameters including but not limited to dwell time, catheter insertion outcomes, and adverse event rates. Critical clinical parameters extracted from these studies met standards set forth in the guidelines for the State of the Art. There were no unforeseen adverse events or other high occurrences of adverse events detected in any of the clinical activities. Medcomp® STHD catheters are subjected to, and must pass, simulated use testing intended to replicate 30 days use as part of device development. The Duo-Flow® III Catheter passed this testing. Clinical guidelines recommend to limit the use of temporary, noncuffed, nontunneled dialysis catheters to a maximum of 2 weeks (KDOQI 2019), however, duration of use of these catheters has varied in available clinical evidence identified by the manufacturer to date. Although Medcomp® catheters materials contain non-degradable polymers, fully functional catheters may be removed for other reasons, such as intractable infection or change of therapy. Published clinical literature does not always focus on the physical lifetime of a catheter for these reasons. In the case of the Duo-Flow® III Catheter, 66 catheters had a mean dwell time of 26.53 days [95%CI: 17.92 – 35.14 days] duration of use that has been found in clinical use reported to date. Based on this information, the Duo-Flow® III catheters have a 30 day lifetime; however, the decision to remove and/or replace the catheter should be based on clinical performance and need, and not any predetermined point in time.

Summary of Clinical Data Related to the Equivalent Device

Clinical evidence from published literature and PMCF activities has been generated specific to known and unknown variants of the subject device. The equivalency rationale in the updated clinical evaluation report will demonstrate that the clinical evidence available for these variants is representative of the range of device variants in the device family. There are no clinical or biological differences between variants within the subject device family, and the potential impact of the technical differences will be rationalized in the updated clinical evaluation report.

Summary of Clinical Data from Pre-Market Investigations (if applicable)

No pre-market clinical devices were used for the device’s clinical evaluation.

The Duo-Flow® III Multicenter Patient-Level Data Collection Survey acquired responses from healthcare personnel familiar with use and/or care of Medcomp® Duo-Flow® III STHD catheters. This survey was distributed to customers in European Union member states and other countries in the European region. Persons surveyed are representative of the broad spectrum of users within the user population. 7 survey responses were collected from 4 countries representing 67 Duo-Flow® III device cases. The database included information on 67 Duo-Flow® III Catheter cases with dates of insertion ranging from 02 February 2021 to 10 January 2023 and dates of removal (or last known follow-up) ranging from 03 March 2021 to 17 January 2023. Each case represented a Medcomp device insertion. 67 Duo-Flow® III cases inclusive of several variant devices across catheter length (15cm, 17.5cm, 20cm, 25cm) and lumen configuration (Straight, Curved Extensions) were collected. All device cases were indicated for hemodialysis. The following outcome measures were confirmed to be within State of the Art safety and performance outcome measures from published literature for Medcomp Duo-Flow® III catheters.
