3. Device Description

Device Name: Symetrex®

Description of Device: The Symetrex® Catheters are long-term catheters. The catheters are double tubed. The catheters remove and return blood through two separate lines. Each tube connects through an extension line. The transition between lumen and extension is in a central hub. Each tube has the priming volume marked by colored rings on the clamps on the extensions. A polyester cuff on the catheter tubing helps attach the catheter to the patient.

Device Name: Symetrex®

Materials / Substances in Contact with Patient Tissue:

The percentage ranges below are based on catheter weights. The 15.5F x 19cm catheter without sideholes weighs 11.88 grams. The 15.5F x 19cm catheter with sideholes weighs 11.87 grams. The 15.5F x 42cm catheter without sideholes weighs 15.60 grams. The 15.5F x 42cm catheter with sideholes weighs 15.59 grams.

Note:The device should not be used if you are allergic to the above materials.

Note:Accessories containing stainless steel may contain up to 4% weight of the CMR substance cobalt.

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. Long-term access may occur in some cases. For example, when there are problems supporting an AV fistula or graft.

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

4. Risks and Warnings

Contact your healthcare professional if you believe you are experiencing side-effects related to the device or its use or if you are concerned about risks. This document does not replace a consultation with your healthcare professional if needed.

How Potential Risks Have Been Controlled or Managed

There have been 27,900 devices sold since January 2020. There are side effects and risks associated with the device. These include: • Infection • Bleeding • Catheter Removal • Catheter 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 Symetrex® catheter is associated with risks. These include: • Procedural Delays • Thrombosis • Infections • Perforations • Embolism • Cardiac Event • Dissatisfaction These risks are consistent with risks of other dialysis catheters. They are not unique to the Medcomp product. Some of the most common reactions include infection. Infection may be associated with general surgical procedure and hospitalization. Infection may not always be device-related.

Warnings and Precautions

The below are warnings, precautions, or measures to be taken by patient: • To reduce the risk of bacteria entering the catheter, wear a mask over your nose and mouth whenever the catheter is accessed. • Keep the catheter dressing clean and dry. The dressing should be changed by a medical professional at each dialysis session. • Avoid letting the catheter or catheter site go under water. Moisture near the catheter site can potentially lead to an 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 April 2024 to 31 March 2025.

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

Clinical Background of Device

The Symetrex® catheter has been available since 2016. The CE Mark was received in October 2016. US FDA clearance was in August 2017. All models included are planned for distribution in the European Union.

Clinical Evidence for CE-Marking

The clinical literature review identified 0 articles relating to the safety and/or performance of the subject device when used as intended. Two patient level data activities received information on 65 catheters. 38 user surveys have been received relating to this device. Findings from the user surveys and data activities support the performance of the subject device. All data on the Symetrex® catheter has been evaluated. The benefits of the subject device outweigh the risks when the device is used as intended. The benefit of the device is allowing hemodialysis in patients in whom other therapies or conservative care are not desirable by the physician.

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 long-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 are acceptable when weighed against the benefits. There were 34 complaints for 27,900 units sold from 01 January 2020 to 31 March 2025. The complaint rate is 0.122%.

6. Possible Therapeutic Alternatives

When considering alternative treatments, it is recommended to contact your healthcare professional who can consider your individual situation. The Kidney Disease Outcomes Quality Initiative (KDOQI) 2019 clinical practice guidelines have been used to support the below recommendations for treatments.

7. Suggested Profile and Training for Users

The catheter should be inserted, manipulated, and removed by a qualified, licensed physician or other qualified health care professional under the direction of a physician. In certain circumstances, patients who may be suitable for home hemodialysis may manipulate the external connections of the catheter. Consult International Society of Hemodialysis guidelines. If home dialysis is recommended, you will undergo thorough training. The objectives of the training program are: 1) Give you information to dialyze safely at home. 2) Enable you to monitor and manage your disease. 3) Help you cope with fears and restrictions of home hemodialysis. The ideal nurse trainer-to-patient ratio is typically 1:1. A training schedule will be created. Training will be individualized to your needs.
