No
The document describes a cryosurgical system that uses a balloon cooled by nitrous oxide to ablate tissue. There is no mention of AI or ML in the device description, intended use, or performance studies. The system appears to be a purely mechanical and thermal device.
Yes
The device is described as a "cryosurgical tool" for "ablation of Barrett's Esophagus with dysplasia" and its function is to "ablate unwanted tissue by application of extreme cold," which directly indicates a therapeutic purpose.
No
Explanation: The device is described as a cryosurgical tool used for ablating tissue by the application of extreme cold. Its intended use is described as a "cryosurgical tool" for "ablation", which are therapeutic actions, not diagnostic.
No
The device description clearly outlines multiple hardware components including a catheter, controller, foot pedal, and cartridge, indicating it is a physical medical device system, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is described as a "cryosurgical tool" for "ablation of Barrett's Esophagus with dysplasia." This is a therapeutic procedure performed directly on the patient's tissue.
- Device Description: The device description details a system for applying extreme cold to tissue for ablation. This is a surgical/therapeutic device, not a device used to examine specimens in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information based on such analysis. The device's function is to physically alter tissue.
IVD devices are used to examine specimens obtained from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device's purpose is to treat a condition by ablating tissue, which falls under the category of a therapeutic medical device.

Device Description
The subject device is a cryosurgical unit with a nitrous oxide cooled balloon that is compatible with commercially available endoscopes with a minimum working channel inner diameter of 3.7 mm and maximum length of 105 cm. The subject device is a cryosurgical system comprised of four components including a Catheter (sterile, single use), Controller (non-sterile, reusable), Foot Pedal (non-sterile, reusable), and Cartridge (non-sterile, single use).
The subject device is used to ablate unwanted tissue by application of extreme cold. The balloon at the distal end of the Catheter comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected is by adjusting the endoscope and Controller. The nitrous oxide spray cools the balloon to ablate the unwanted tissue, and the nitrous oxide exhausts through the Controller.
The only modifications that are being made are to the C2 CryoBalloon Controller hardware and software to correct the controller random reset issues and to improve the handheld controller unit operational reliability. In addition, controller software has been updated to log data periodically to a log file, improve the RF encryption algorithm, replace the motor encoders and address open software bugs.

II. PREDICATE DEVICE: C2 CryoBalloon Ablation System, PENTAX Medical (K203024)
III. DEVICE DESCRIPTION
The subject device is a cryosurgical unit with a nitrous oxide cooled balloon that is compatible with commercially available endoscopes with a minimum working channel inner diameter of 3.7 mm and maximum length of 105 cm. The subject device is a cryosurgical system comprised of four components including a Catheter (sterile, single use), Controller (non-sterile, reusable), Foot Pedal (non-sterile, reusable), and Cartridge (non-sterile, single use).

The subject device is used to ablate unwanted tissue by application of extreme cold. The balloon at the distal end of the Catheter comes in contact with tissue and is inflated with nitrous oxide. Tissue is visualized through the pre-inflated balloon, and the treatment site is selected is by adjusting the endoscope and Controller. The nitrous oxide spray cools the balloon to ablate the unwanted tissue, and the nitrous oxide exhausts through the Controller.
IV. INDICATIONS FOR USE
The C2 CryoBalloon Ablation System is intended for use as a cryosurgical tool in the field of general surgery, specifically for endoscopic applications, to include ablation of Barrett's Esophagus with dysplasia.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE V. PREDICATE DEVICE
Cryoablation is the fundamental technological principle for both the subject C2 CryoBalloon Ablation System and the predicate C2 CryoBalloon Ablation System. Both the subject device and predicate device are based on the same endoscopic instrumentation for use as a cryosurgical tool in the field of general surgery, specifically for endoscopic applications, to include ablation of Barrett's Esophagus with dysplasia.
The subject C2 CryoBalloon™ Ablation System has the same technological characteristics to the legally marketed predicate device (K203024). The subject devices and predicate/reference devices are based on the following same technological elements:
- Inserted through an endoscope to access the treatment site
- Application of cryogen to ablate (freeze) the unwanted tissue
- Use of a compliant balloon to position the treatment diffuser and to contain and 0 exhaust the cryogen
- User-controlled (trigger/foot pedal) to release cryogen 0
- o Software activated Controller
The only modifications that are being made are to the C2 CryoBalloon Controller hardware and software to correct the controller random reset issues and to improve the handheld controller unit operational reliability. In addition, controller software has been updated to log data periodically to a log file, improve the RF encryption algorithm, replace the motor encoders and address open software bugs.
The changes in the subject device have been evaluated through performance testing and raise no issue of safety and effectiveness of the device as these differences have no effect on the performance, function or general intended use of the device.
There are no changes to the reprocessing (cleaning) of the Controller and Foot Pedal components. The subject device and predicate device are both intended to be cleaned and disinfected by the user between patient use.

VI. PERFORMANCE DATA
Performance data was provided in support of the substantial equivalence determination. Design verification and validation testing was performed on the subject PENTAX Medical C2 CryoBalloon™ Ablation System to evaluate physical, reliability, and safety specifications. The acceptance criteria have been satisfied for all tests.
VII. EMC AND ELECTRICAL SAFETY
The acceptable level of electromagnetic compatibility (EMC) and electrical safety (ES) for the PENTAX Medical C2 CryoBalloon™ Ablation System were confirmed by the testing to the following standards: IEC 60601-1-2:2014 4th Edition and ANSI/AAMI/IEC/EN 60601-1-2:2014
VIII. SOFTWARE
The modified controller of the C2 CryoBalloon Ablation System was subjected to the Software Verification and Validation testing to show that the performance of the device is substantially equivalent to the predicate device. The subject device successfully met all the acceptance criteria for the software verification and validation testing.
IX. CONCLUSION
The subject C2 CryoBalloon Ablation System has the same clinical attributes, technological characteristics, intended use, and expected performance as the legally marketed predicate device, C2 CryoBalloon Ablation System (K203024). The performance testing results demonstrate that the subject C2 CryoBalloon Ablation System with modified Controller hardware and software changes should perform as intended in the specified use conditions and should perform comparably to the legally marketed predicate device that is currently marketed for the same intended use.
