More Information

No
The document describes a mechanical device (a stent) and its delivery system. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities. The performance studies focus on mechanical properties.

Yes.
The device is indicated for the palliation of malignant neoplasms in the biliary tree, which is a therapeutic intervention aimed at alleviating symptoms and improving quality of life.

No

The device is a stent used for palliation of malignant neoplasms in the biliary tree, which is a treatment (therapeutic) function, not a diagnostic one.

No

The device description explicitly states it is a "balloon-expandable, stainless steel stent which is premounted on the delivery system," indicating it is a physical medical device, 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 "palliation of malignant neoplasms in the biliary tree." This describes a therapeutic intervention performed directly on a patient's anatomy.
  • Device Description: The device is a "balloon-expandable, stainless steel stent" designed to be implanted in the biliary tree. This is a medical device used for treatment, not for testing samples outside the body.
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is mechanical support within the biliary tree.

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.
