The summary describes a cryosurgical system that uses liquid nitrogen for tissue ablation. There is no mention of AI, ML, image processing, or any data-driven decision-making components. The system appears to be a purely mechanical and cryo-based device.
Yes
The device is described as a "cryosurgical tool for destruction of unwanted tissue" and performs "cryo-ablation procedures" to "destroy unwanted tissue," which are therapeutic actions.
No
The device is described as a "cryosurgical tool for destruction of unwanted tissue" and functions by applying extreme cold to destroy tissue. Its purpose is therapeutic (ablation), not diagnostic.
No
The device description clearly outlines hardware components like a liquid nitrogen tank and a cryocatheter, indicating it is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as a cryosurgical tool for destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications." This describes a surgical procedure performed directly on the patient's body, not a test performed on a sample taken from the body.
- Device Description: The device description details a system that applies extreme cold to tissue in situ (in its original place) to destroy it. This is a therapeutic intervention, not a diagnostic test.
- Lack of IVD Characteristics: The description does not mention analyzing biological samples (like blood, urine, tissue biopsies), detecting specific analytes, or providing diagnostic information about a patient's condition based on laboratory testing.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device performs a therapeutic action directly on the tissue within the body.

Device Description
The CryoSpray Ablation™ System is used to destroy unwanted tissue by application of extreme cold to a selected site. Liquid Nitrogen is stored in a tank and then propelled through a cryocatheter to perform the cryo-ablation procedure. The catheter, an accessory component of the CSA System, is placed in the appropriate position through the use of visual observation. The cryo-catheter applies the cryogen to a selected area and freezes the unwanted tissue. The catheter detailed in the K060555 submission is of a single lumen, straight tip design.

Premarket Notification
SprayGenix™ Cryo Ablation System KOROSSS
Company History:
CSA Medical, formerly CryMed Technologies received market clearance for the SprayGenix™ Cryo Ablation System (K060555). The name for the SprayGenix™ Cryo Ablation System was changed to the CryoSpray Ablation™ System as documented in the letter to file dated March 12, 2007.
Device Description:
The CryoSpray Ablation™ System is used to destroy unwanted tissue by application of extreme cold to a selected site. Liquid Nitrogen is stored in a tank and then propelled through a cryocatheter to perform the cryo-ablation procedure. The catheter, an accessory component of the CSA System, is placed in the appropriate position through the use of visual observation. The cryo-catheter applies the cryogen to a selected area and freezes the unwanted tissue. The catheter detailed in the K060555 submission is of a single lumen, straight tip design.

Description of Modification:
The only device modification presented in this Special 510k submission involves a tip configuration modification for the cryocatheter. It was desirable to allow the end user's the ability to direct the cryogen radially. While the identical materials are used as compared to the catheter listed in submission K060555, the end of cryo-catheter is closed and a side hole is located in the distal side the catheter, allowing a radial spray of the cryogen. All other dimensional specifications are identical to the catheter detailed in submission K060555. The surface area of the radial hole of the catheter is similar to the hole in the lumen opening of the straight spraying catheter. Refer to Attachments 5 and 6.
Indications for Use:
The CryoSpray Ablation™ System is intended to be used as a cryosurgical too! for destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications.
The intended use of the modified catheter, as described in its labeling, has not changed as a result of the tip configuration modification. Refer to Attachment 3.
Technical Characteristics:
The modification to the catheter does not change the operating principals or mechanism of action for the CryoSpray Ablation System and it is substantially equivalent to the above listed predicate devices.
Summary:
Based on the principles of operation, design, materials and intended use, the modification to the Straight Catheter to produce a Directional Catheter results in a CryoSpray Ablation™ System that is substantially equivalent to devices currently marketed in the United States.
Declaration of Conformity: Refer to Attachment 2.

Dear Ms. Cartledge:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
