Perma-Hand Suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori (B. mori) of the family Bombycidae.

The sutures are processed to remove the natural waxes and gums, dyed black and coated with a special wax mixture.

Perma-Hand Suture is indicated for use in general soft tissue approximating and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures.
