The description focuses on a mechanical system for heat transfer and fluid circulation, with no mention of AI/ML algorithms for control, analysis, or decision-making.
Yes
The device is intended to transfer heat to the urethra during urological cryosurgery, which is a therapeutic intervention. Its function is to prevent cold thermal energy dissipation from the urethral mucosa during the procedure.
No
The device is intended to transfer heat to the urethra during urological cryosurgery, which is a therapeutic function, not a diagnostic one. It warms the urethra to protect it during a procedure, it does not assess a medical condition or provide information for diagnosis.
No
The device description clearly outlines multiple physical components (catheter, tubing, flow indicator, etc.) and mentions its use in conjunction with hardware like a warming unit and peristaltic pump. It is a hardware-based medical device kit.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "transfer heat to urethra during urological cryosurgery." This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a catheter kit used to circulate warmed fluid within the urethra to protect it during cryosurgery. This is a physical intervention, not a test performed on a sample taken from the body.
- Lack of Diagnostic Purpose: There is no mention of the device being used to diagnose a condition, measure a substance in a sample, or provide information about a patient's health status based on in vitro analysis.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Device Description
The Urethral Warming Catheter Kit (CRYO-77) warms a patient's urethra during the cryoablation procedure by transferring heat through a catheter inserted within the urethra. The catheter contains fluid that is warmed using dry heat from an electrical heating unit (Warming unit) and circulated in a closed circuit using a peristaltic pump (circulating pump).
The Urethral Warming Catheter Kit contains the following:
- 22 french urethral balloon catheter
- Tubing
- Flow indicator
- Tubing clamp
- IV bag decanter
- Two luer connections
- Tube placement markers for pump
- Tube retainer
and is used in conjunction with a compatible fluid warming system and peristaltic pump. The fluid warming system supplies a steady flow of warm, sterile water or saline to the urethral catheter which transfers heat to the urethra during urological cryosurgery. The water or saline is circulated by a peristaltic pump from the catheter to the I.V. bag in a closed circuit.
The Urethral Warming Catheter Kit is recommended to use with 3M™ Ranger™ Model 245 Fluid Warmer System and 3M™ Ranger™ Fluid Warming Set, and a peristaltic pump meeting the following technical specifications:
- Pump mechanism- Roller-type peristaltic pump
- Compatible Pump head- Masterflex L/S® Easy-Load for use with 13, 14, 16, 25, 17, 18 tubing (07518-60, 77200-60, 77201-60 or similar)
- Operational nominal flow rate- 500 mL/min
- Minimum Pump RPM range 0-300RPM
- Maximum Continuous Pressure- 40PSIG
- Rated voltages 100V-240V; 50/60Hz
- IEC 61010 certified
The compatible fluid warming system and peristaltic pump are not owned or distributed by Varian. The system integration of Urethral Warming Catheter Kit with compatible accessories is the responsibility of end user.

VII. Performance Data (Non-Clinical Testing)
Design Verification and Design Validation testing were completed to demonstrate that the Urethral Warming Catheter Kit performs as intended and meets its essential performance specifications.
- Catheter to include flow indicator to ensure fluid is not impeded and flowing correctly through closed circuit system.
- · Catheter is closed-circuit, free of fluid leaking or component separation
- Catheter is designed to dissipate cold thermal energy from the urethral mucosa
Bench testing included testing of the system, including:
- · Biocompatibility Testing in accordance with ISO 10993 series of standards, including ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 10993-12
- Sterilization Validation in accordance with EN 556-1, ANSI/AAMI ST67, ISO 11137-1, ISO 11137-2, ISO 11737-1 and ISO 11737-2
- Usability Testing in accordance with IEC 62366-1 Annex C
No animal studies or clinical tests have been included in this pre-market submission.
VIII. Determination of Substantial Equivalence to the Predicate Device
A subset of technological characteristics and features of the subject device differs from the predicate device. These differences are all considered to be enhancements of the predicate, intended to configure urethral warming catheter as a stand-alone device compatible with onmarket available accessories.
The indications for use are substantially the same as the predicate device. Further, there are no changes in the principle of operation of the devices. The Verification and Validation demonstrates that the device is as safe and effective as the predicate. Varian therefore believes the data demonstrates that Varian Urethral Warming Catheter Kit is substantially equivalent to the predicate device, Endocare Urethral Warming System.
IX. Conclusion
The assessment following the outcomes observed in the performance testing determines that the Urethral Warming Catheter Kit conforms to the defined user needs and intended uses. Varian therefore considers the Urethral Warming Catheter Kit to be safe and effective and to perform at least as well as the predicate device.
