Intended Use
Non absorbable Surgical Silk Suture is indicated for use in general soft tissue approximation and/or ligation, but not for use in ophthalmic procedures, cardiovascular and neurological procedures. The device is limited to use where short term wound support (7-10 days) is required and can be left in place for a maximum of 10 days.
Device Description
Non absorbable Surgical silk Suture is a nonabsorbable, braided surgical suture which is supplied sterile, surgical suture composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori of the family Bombycidae. Silk for braided material is processed to remove the natural waxes and gums. Silk suture is dyed black(Logwood extract) and coated with silicone. The quantity of color additive is not to exceed 1.00% by weight of the suture. The device will be offered in diameters ranging from USP size 6-0 through 2 and available in length varying from 45cm to 150cm with or without needles attached. Silk suture meets all the requirements of USP for nonabsorbable surgical suture. The suture needle are made from medical stainless steel, the grade of medical stainless steel is SUS 420 J2.

No
The description focuses on the material composition and physical properties of a surgical suture, with no mention of AI or ML capabilities.

No.
This device is a surgical suture used for short-term wound support and ligation, which are mechanical functions for wound closure and not inherently therapeutic in the sense of treating a disease or condition actively.

No
Explanation: The device is a surgical suture used for tissue approximation and/or ligation, which are therapeutic actions, not diagnostic ones.

No

The device description clearly states it is a physical surgical suture made of silk and stainless steel needles, which are hardware components.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside the body (in vitro).
  • Device Description: The provided text describes a surgical suture, which is a material used to close wounds and hold tissues together within the body (in vivo).
  • Intended Use: The intended use is for "general soft tissue approximation and/or ligation," which is a surgical procedure performed directly on the patient.

The description clearly indicates a device used during surgery on a living patient, not a test performed on a sample in a laboratory.
