No
The document describes a cryosurgical unit that uses the Joule-Thomson principle for tissue freezing. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is intended for the destruction of tissue during surgical procedures and for the removal of various foreign bodies, necrotic tissue, and for tissue biopsy by cryoadhesion, as well as for treating a wide range of medical conditions listed under 'Clinical Indications for Cryosurgery' across multiple medical specialties.
No
The device is described as a cryosurgical unit intended for the destruction or removal of tissue by applying extreme cold. Its function is to perform surgical procedures, not to diagnose conditions.
No
The device description explicitly details hardware components such as a cryosurgical unit, probes, connecting hose, footswitch, and a cart, indicating it is a physical medical device, not software-only.
Based on the provided information, the ERBECRYO 2 Cryosurgical Unit and Accessories is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for the destruction and removal of tissue during surgical procedures by applying extreme cold. This is a therapeutic and surgical intervention performed directly on the patient's body.
- Device Description: The device description details a system that physically interacts with tissue to freeze it. It uses a cryosurgical unit, probes, and gas to achieve this.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens outside of the body (in vitro) to provide diagnostic information. IVD devices are typically used to analyze blood, urine, tissue samples, etc., in a laboratory setting to diagnose diseases or conditions.
The ERBECRYO 2 is a surgical device used for therapeutic purposes (tissue destruction and removal) and is applied directly to the patient. This falls under the category of a medical device used for treatment, not for in vitro diagnosis.

Device Description
The ERBECRYO 2 Cryosurgical Unit and Accessories consists of a cryosurgical unit, probes with a cryosurgical tip, a connecting hose to be connected to a CO2 (Carbon Dioxide) gas bottle and a footswitch for activation. The system is mounted on a cart, which also carries up to two CO2 gas bottles.
The ERBECRYO 2 Cryosurgical Unit and Accessories is used to apply extreme cold to tissue during surgical procedures. The system uses the Joule-Thomson principle where pressurized gas expands through a fine orifice inside the tip of the cryosurgical probe producing a rapid drop in temperature and freezing the probe tip and the surrounding tissue.
The unit and accessories are provided non sterile. The cryoprobes are reusable and directions for cleaning and sterilizing the cryosurgical probes are provided in the Notes on Use.
Design and materials of the ERBECRYO 2 Cryosurgical probes are very similar to the predicate probes.

Similarities and Differences of the Modified Device to the Current Device (Predicate Comparison/Substantial Equivalence)
Similarities: The ERBECRYO 2 Cryosurgical Unit and Accessories has the same basic technology characteristics as the predicate unit and accessories to induce extreme cold to tissue, and the indications for use are the same. Both the proposed and the predicate cryosystems use CO2 gas and are closed systems.
The probes for the proposed and predicate cryosurgical units have the same construction, a similar design and similar materials.
The following features are new in the proposed ERBECRYO 2 Differences: Cryosurgical Unit:
-
The pressure and flow sensors and valves are controlled electronically
-
Pressure readings are shown in the interactive display.
-
The 6 soft keys and the monochrome graphical display provide information to the user and enable user interaction.
-
Timer function for cryoactivation
-
Program memory
-
Counter for number of reprocessing actions of probes
-
Additional low setting (E1). With the default setting (E2), which is equivalent to the performance of the predicate system, the freeze is performed within 2-3 sec (900 mm probes). The low setting gives an option of a "milder freeze".
-
Not suitable for operation with N2O gas
5
- 2 gas bottles with a switch over connector mountable on the system cart (optional) versus one gas bottle in the predicate system.
In contrast the predicate cryosurgical unit operates purely mechanically, without software control, has no interactive display except for a manometer reading of the inlet gas pressure.
The following features are new in the proposed ERBECRYO 2 Cryosurgical probes:
- Different shape and design connector to the cryosurgical units
- The connector contains an EEPROM for instrument recognition
- Cap for closing of the plug during reprocessing is fixed to the plug
- Additional 1050 mm probe (predicate probes are 900 mm length)
Physical and Performance Testing
Physical and performance characteristics of the ERBECRYO 2 Cryosurgical system are comparable to those of the predicate system, as is shown in bench testing. The system conforms with the following standards:
EN ISO 14971:2009 Application of Risk Management to Medical Devices

No studies in the living animal have been performed. As performance and safety testing were done as bench testing and the surgical application of cryotechnology is well established, the applicant does not consider it necessary to perform testing in the living animal. The intended use was validated in comparative tissue studies against the predicate system. The performance was similar for both systems.

Conclusion
The Proposed Device, the ERBECRYO 2 Cryosurgical System and Accessories, is a further development of the ERBOKRYO CA Cryosurgical System and Accessories cleared with K051509. The predicate device, ERBOKRYO CA, is a simple supply unit, which does not control the gas flow or application time and does not give the user any possibilities for different settings. Software has been added to the proposed model, ERBECRYO 2, to control these parameters.
In summary the proposed and predicate systems essentially differ in the software added to the proposed system to control gas flow and pressure and record the application time. These parameters are shown in the new interactive display.
Therefore the proposed system provides state of the art technology and a safer use and there are no new issues, which could raise concern for safety and efficacy with the ERBECRYO 2 Cryosurgical Unit and Accessories.
