Intended Use
The Polypectomy Snares are used endoscopically in the removal of diminutive polyps, and pedunculated polyps within the GI tract.
Device Description
The proposed device Polypectomy Snare is a sterile, single-use endoscopic device, intended to be used endoscopically in the removal diminutive polyps, sessile polyps, and pedunculated polyps from within the GI tract. The Polypectomy Snares consists of a flexible wire cable and loop which can be extended and retracted from the snare's flexible outer sheath using a handle. When passed through an endoscope the snare can be activated to deliver a monopolar electrical current to cut and cauterize tissue with the loop. The proposed device has eighteen (18) specifications; the main differences of these specifications are dimension and if the loop can be rotatable with the rotation of the handle.
More Information

Not Found

No
The device description and performance studies focus on the mechanical and electrical aspects of a traditional polypectomy snare, with no mention of AI or ML capabilities.

Yes
The device is used to remove polyps from the GI tract, delivering an electrical current to cut and cauterize tissue, which directly treats a medical condition.

No

The device is used for the removal of polyps and not for diagnostic purposes; it is a therapeutic device.

No

The device description clearly states it is a physical, sterile, single-use endoscopic device with a wire cable, loop, sheath, and handle, designed to deliver electrical current for cutting and cauterization. This is a hardware device, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Polypectomy Snare is a surgical instrument used within the body (in the GI tract) to physically remove polyps. It uses mechanical action (snaring) and electrical current (cutting and cauterization) directly on the tissue.
  • Lack of Sample Analysis: The device does not analyze any biological samples taken from the patient. It interacts directly with the tissue in situ.

The description clearly indicates the device's purpose is the physical removal of polyps during an endoscopic procedure, which is a surgical intervention, not an in vitro diagnostic test.
