Note:Per the instructions for use, the device is contraindicated for patients with known or suspected allergies to the above materials.

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.

• 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.

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 Hemo-Cath® ST 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 Hemo-Cath® ST Catheter, 54 cases had a mean dwell time of 46.9 days [95% CI: 15.8 - 78 days] (Sombolos et al., 2004) duration of use that has been found in clinical use reported to date. In the case of the Medcomp® Hemo-Cath® ST Single Lumen Catheter, 64 cases had a mean dwell time of 41.5 days [Range: 4 - 134 days] (Montagnac et al., 1997) duration of use that has been found in clinical use reported to date. Based on this information, the Hemo-Cath® ST 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.
