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. This catheter has two separate tubes. The tubes go into a large vein. The vein is usually the internal jugular vein. Blood withdraws through one tube 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 tube. 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.

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

• 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 in the 6.5F Tesio® Catheter IFUs 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. Additional warnings and cautions listed in the 6.5F Tesio® Catheter IFUs are as follows:
• Physician discretion is strongly advised when inserting this catheter in patients who are unable to take or hold a deep breath.
• Patients requiring ventilator support are at increased risk of pneumothorax during subclavian vein cannulation, which may cause complications.
• Extended use of the subclavian vein may be associated with subclavian vein stenosis.
• The length of wire inserted is determined by the size of the patient. Monitor patient for signs of arrhythmia throughout this procedure. The patient should be placed on a cardiac monitor during this procedure. Cardiac arrhythmia may result if the guidewire is allowed to pass into the right atrium. The guidewire should be held securely during this procedure.
• DO NOT grasp and pull the guidewire prior to releasing the J-Straightener. Damage to the guidewire may occur if it is pulled against the restraint of the J-Straightener.
• DO NOT bend the sheath/dilator during insertion as bending will cause the sheath to prematurely tear. Hold sheath/dilator close to the tip (approximately 3cm from tip) when initially inserting through the skin surface. To progress the sheath/dilator towards the vein, regrasp the sheath/dilator a few centimeters (approximately 5cm) above the original grasp location and push down on the sheath/dilator. Repeat procedure until sheath/dilator is fully inserted.
• Never leave sheaths in place as indwelling catheters. Damage to the vein will occur.
• Do not tunnel through muscle.
• Assure that all air has been aspirated from catheter and the extensions. Failure to do so may result in air embolism.
• Failure to verify catheter placement may result in serious trauma or fatal complications.
• Care must be taken when using sharp objects or needles in close proximity to catheter lumen. Contact from sharp objects may cause catheter failure.
• Only clamp catheter with in-line clamps provided.
• Extension clamps should only be open for aspiration, flushing, and dialysis treatment.
• Always review hospital or unit protocol, potential complications and their treatment, warnings, and precautions prior to undertaking any type of mechanical or chemical intervention in response to catheter performance problems.
• Only a physician familiar with the appropriate techniques should attempt the following procedures.
• Due to the risk of exposure to HIV (Human Immunodeficiency Virus) or other blood borne pathogens, health care professionals should always use Universal Blood and Body Fluid Precautions in the care of all patients.
• Do not use excessive force as this may break the catheter. If the catheter does not withdraw from the tunnel after moderate force has been applied, or the catheter is removed without the cuff, the following steps may be taken to remove the catheter.
• Do not pull distal end of catheter through incision as contamination of wound may occur.

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® catheters are subjected to, and must pass, simulated use testing intended to replicate use 3 times per week for 12 months as part of device development. The 6.5F Tesio® Catheter passed this testing. Although Medcomp® catheters contain no materials which degrade over time, fully functional catheters may be removed for other reasons, such as intractable infection, change of therapy (such as Renal replacement (transplant) or use of an arterio-venous graft/fistula). Published clinical literature does not always focus on the physical lifetime of a catheter for these reasons. In the case of the 6.5F Tesio® Catheter, 11 catheters had a median 244 day [Range: 1 - 344 days] duration of use that has been found in clinical use reported to date. Based on this information, the 6.5F Tesio® Catheter has a 12-month 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.

6. Possible Therapeutic Alternatives

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. As per guidelines stated from the International Society of Hemodialysis, if home dialysis is recommended, each patient will undergo a thorough training in order to obtain optimal results from home dialysis treatments. The objectives of the training program are to (1) provide the appropriate amount of information to ensure that the patient will be able to dialyze safely at home; (2) enable the patient to monitor and manage other elements of his or her chronic kidney disease, such as obtaining samples for lab work and maintaining appropriate nutrition and diet; and (3) help the patient and his or her care partner(s) cope with barriers and fears associated with home HD During training, the patient will also receive technical education on the operations and maintenance of the water treatment system. During training, the ideal nurse trainer-to-patient ratio is typically 1:1. An idealized schedule of training is created, with weekly areas of focus and training objectives. In practice, however, training is individualized to address any identified learning barriers or risks for failure.
