NOVAFIL™ nonabsorbable monofilament surgical sutures are composed of polybutester, a copolymer of butylene terephthalate and polytetramethylene ether glycol.
Characteristics
The unique properties of NOVAFIL™ monofilament sutures are attributed to the composition and structure of the polybutester fiber which give the suture:
Suppleness and easy handling
Unique elasticity and flexibility
Excellent knot security
Less tissue drag and smooth knot run-down
Fray resistance
Unique resistance to creep and structural fatigue
Indications
NOVAFIL™ polybutester sutures are indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular and ophthalmic surgery, but not in microsurgery and neural tissue.
Contraindications
The use of this suture is contraindicated in patients with known sensitivities or allergies to its components. This suture, being non-absorbable, should not be used where extended approximation of tissue is required.
Actions
NOVAFIL™ monofilament sutures elicit a minimal, transient acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue. NOVAFIL™ monofilament sutures are stable against the action of tissue enzymes and do not degrade.
Tensile Strength
NOVAFIL™ monofilament sutures are nonabsorbable, and no significant change in strength retention is known to occur in vivo.
