No
The description focuses on the mechanical and electrical components of the device and does not mention any AI or ML capabilities.

No
The device is used to create an atrial septal defect, which is a procedure rather than a therapeutic treatment for a disease or condition. It is an access tool to facilitate other procedures.

No

The device is described as creating an atrial septal defect by puncturing the Fossa Ovalis and delivering radiofrequency energy. This is a therapeutic, interventional procedure, not a diagnostic one. While it can infuse solutions like contrast media, this is secondary to its primary therapeutic function.

No

The device description clearly details hardware components such as a cannula, dilator, guidewire, and adapter cable, and mentions electrical safety and mechanical testing.

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

Here's why:

  • Intended Use: The intended use is to "create an atrial septal defect in the heart" and "infusing solutions". This is a surgical/interventional procedure performed on the patient's body, not a test performed on a sample taken from the patient's body.
  • Device Description: The description details a system used to puncture tissue and deliver energy, which is consistent with a surgical/interventional device.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device is used for a therapeutic/interventional purpose.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
