AtriCure Cryo Module Indication for Use Statement: The AtriCure Cryo Module is a non-sterile, reusable device which delivers cryogenic energy, namely nitrous oxide, to AtriCure's cryo-ablation probes. cryolCE™ Indication for Use Statement: AtriCure's cryoICE™ cryo-ablation probes are sterile, single use devices intended for use in the cryosurgical treatment of cardiac arrhythmias by freezing target tissues, creating an inflammatory response (cryonecrosis) that blocks the electrical conduction pathway. The probe is also intended for use in blocking pain by temporarily ablating peripheral nerves.
Device Description
The AtriCure Cryo Module (ACM) unit is a non-sterile reusable electro-mechanical and pneumatic cryogenic surgical system that delivers a cryogenic energy source, namely Nitrous Oxide, to the AtriCure cryo-ablation probes. The AtriCure's cryo-ablation probe (CRYO2) is a sterile, single use, cryosurgical device to be used in conjunction with the AtriCure Cryo Module or ACC2 Cardiac Cryosurgical System [K811390] to freeze target tissue, blocking the electrical conduction pathways by creating an inflammatory response or cryonecrosis. The cryolCE™ probe can also be used to temporarily ablate peripheral nerves.
More Information

No
The document describes a cryosurgical system that uses cryogenic energy to ablate tissue. There is no mention of AI or ML in the intended use, device description, or performance studies. The testing focuses on the mechanical, electrical, and performance aspects of the hardware and software, not on any learning or adaptive capabilities.

Yes
The device is described as being used for the "cryosurgical treatment of cardiac arrhythmias" and "to block pain by temporarily ablating peripheral nerves," which are therapeutic applications. It creates a "cryonecrosis that blocks the electrical conduction pathway," indicating direct treatment of a medical condition.

No

The device description and indications for use clearly state its purpose is for "cryosurgical treatment" and "ablating" tissues, which are therapeutic actions, not diagnostic ones.

No

The device description explicitly states it is an "electro-mechanical and pneumatic cryogenic surgical system" and includes hardware components like the "AtriCure Cryo Module (ACM) unit" and "AtriCure's cryo-ablation probe (CRYO2)". While software validation is mentioned, it is part of a larger hardware system.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use statements clearly describe a device used for surgical treatment (cryosurgical treatment of cardiac arrhythmias and temporary ablation of peripheral nerves) by directly interacting with and modifying tissue within the body.
  • Mechanism of Action: The device works by delivering cryogenic energy (nitrous oxide) to freeze target tissues, creating a physical effect (cryonecrosis) to block electrical conduction or pain. This is a direct therapeutic intervention, not a diagnostic test performed on samples outside the body.
  • Device Description: The description reinforces the surgical nature of the device, highlighting its role in a "cryogenic surgical system" used to "freeze target tissue."
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.) or providing diagnostic information about a patient's condition based on such analysis. The device's function is purely therapeutic/interventional.

IVDs are devices intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, treatment, or prevention of disease. This device does not fit that description.
