POLYSORB
TM
coated, braided synthetic absorbable sutures are composed
of LACTOMER
TM
glycolide/lactide copolymer which is a synthetic polyester
composed of glycolide and lactide derived from glycolic and lactic acids.
POLYSORB
TM
sutures are prepared by coating the suture with a mixture of
caprolactone/glycolide copolymer and calcium stearoyl lactylate.
The advanced extrusion process of the molecule of LACTOMER
TM
9-1,
the exclusive braiding process and coating system give the suture:
• Excellent strength over the critical wound healing period
• Excellent knot security
• Excellent handling
• Predictable absorption profile
POLYSORB
TM
sutures are indicated for use in soft tissue approximation or liga-
tion and ophthalmic surgery, but not in cardiovascular or neural tissue.
POLYSORB
TM
sutures, being absorbable, should not be used where extended
approximation of tissue is required.
POLYSORB
TM
sutures elicit 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 POLYSORB
TM
sutures occurs by means of hydrolysis, where the LACTOMER
TM
glycolide/
lactide copolymer is broken down to glycolic and lactic acids which are subse-
quently absorbed and metabolized by the body.
Subcutaneous tissue implantation studies in rats indicate POLYSORB
TM
sutures
are approximately 140% of USP and EP minimum knot strength initially, are
approximately 80% at two weeks and approximately 30% at three weeks
post-implant.
Absorption begins as a loss of tensile strength without appreciable loss of
mass. Absorption of POLYSORB
TM
sutures is essentially complete between the
56th and 70th day.
Ethylene oxide
POLYSORB
TM
sutures are available in USP sizes 2 (5 metric) through 8-0 (0.4
metric). They are available undyed (natural) or dyed (violet). The sutures are
supplied sterile, in pre-cut lengths or ligating reels; non-needled or affixed to
various needle types, using both permanent and removable needle
attachment techniques; in one, two or three dozen boxes.
