Visorb is a braided coated, synthetic absorbable suture, composed of Polyglycolic Acid (PGA) and is available both dyed and undyed. When dyed, only FDA-approved color additives such as FD&C Violet No. 2 are used. The undyed suture is milk white in color. The suture is coated with polycaprolactone and calcium stearate.

Characteristics
Polyglycolic Acid (PGA) exhibits:

• Excellent tensile strength throughout the critical wound healing period

• Excellent knot security

• Excellent handling

• Predictable absorption profile

Indications
Polyglycolic acid is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular and neurological procedures.

Actions
Polyglycolic acid suture elicits a minimal acute inflammatory reaction in tissues, followed by gradual encapsulation of the suture by fibrous connective tissue. Progressive loss of tensile strength and eventual absorption of Visorb sutures occurs by means of hydrolysis.

Tensile Strength
Subcutaneous tissue implantation studies in rats indicate Visorb suture approximately retains 82% of the origional tensile strength at 2 weeks and 56% at 3 weeks. 

Absorption
Absorption begins as a loss of tensile strength without appreciable loss of mass. Absorption of Visorb sutures is essentially complete between 90 and 100 days.

Sterilization
Ethylene oxide.

Packaging
Polyglycolic Acid (PGA) synthetic absorbable suture is braided and dyed with FDA-approved D&C violet No.2, or undyed. The undyed sutures is milk white in color. It is available coated with Polycaprolactone and calcium stearate in USP sizes 6-0 through 3 (metric sizes 0.7-6). The suture is supplied sterile in precut lenths attached to various needle types in one- to three-dozen boxes, or non-needled on ligating reels.
