Prolene Sutures (clear or pigmented) are non-absorbable, sterile surgical suture composed of an isotactic crystalline steroisomer of polypropylene, a synthetic linear polyolefin. The suture is pigment blue to enhance visibility.

Prolene Sutures are indicated for use in general soft tissue approximating and/or ligation, including use in cardiovascular, ophthalmic procedures, and neurological procedures.
