Monolac is a quick absorbable monofilament, produced from Glycolide and ε-Caprolactone copolymer. The thread is not coated and has a smooth, non porous surface. The passage through the tissue is very easy. The thread has no capillary effect and shows no sawing effect. Monolac has a high tensile strength and an even, symmetrical diameter. The thread is soft , but not like a rubber. It shows high flexibility and best handling properties. The knot security is high. Monolac has no antigenic or pyrogenic properties. It is available violet colored (with D & C violet No. 2; CI 60725) or natural in the sizes from EP 0.7 (USP 6/0) to EP 3.5 (USP 0).

Monolac is absorbed in the body by hydrolysis. During absorption the material elicited only a very slight inflammation. The material is degraded into adipic acid, which is completely metabolized in the body.The process begins with a loss of tensile strength, later the loss of mass follows. Monolac violet retains 7 days after implantation approximately 60 % (natural 50 %) of its original tensile strength. After 14 days it will be approximately 30 % (natural 20 %). After approximately 90-120 days the material is completely absorbed.

Indications: Monolac sterile is designed for soft tissue approximation, when an absorbable suture is beneficial. Monolac is used in urology, gynaecology, plastic surgery and in the gastrointestinal surgery.

Reaction in tissue: Slight initial inflammatory reaction in tissue.

Interaction: Sterile Monolac should not be used in tissues which may undergo expansion, stretching or distension or which may require long-term mechanical support.

Chirlac rapid braided is a synthetic absorbable braided surgical suture composed of a polymer of glycolic acid. The substances contained in the coating and suture are nonantigenic and noncollagenous. Sterile Chirlac rapid is available dyed or undyed. Product elicits a minimal acute inflammatory reaction in tissues. Progressive loss of tensile strength and absorption of Chirlac rapid occurs by hydrolysis, where the polymer degrades to glycolic acid which is subsequently absorbed and metabolized by the body. Absorption begins as a loss of tensile strength without appreciable loss of mass. Five days post implantation approximately 60 % of its original tensile strength remains. All of the original tensile strength is lost by approximately 12 to 14 days post implantation.

Indication: Sterile Chirlac rapid is designed for the use in general soft tissue approximation where only short term wound support is required and where the rapid absorption of the suture would be beneficial. Chirlac rapid is indicated for closure of skin, particularly in paediatric surgery, gynaecology (e.g. episiotomies), ophtalmic surgery (e.g. conjunctiva suturing) and for circumcision of oral mucosa.

Reaction in tissue: Slight initial inflammatory reaction in tissue.

Interaction: Sterile Chirlac rapid should not be used in the tissues which may undergo expansion, stretching or distension or which may require a long-term mechanical support longer than seven days. Chirlac rapid suture is not for use in ligation, cardiovascular and neurological tissues.

Chirlac braided is an absorbable, synthetic suture material of extremely high tensile strength made of the homopolymer of hydroacetic acid (glycolic acid). The thread has a homogeneous structure and surface, which gives it low frictional properties, and holds firmly without slipping when knotted. Chirlac threads are coated with an absorbable substance. This reduces the capillary effect, gives the threads excellent holding properties and diminishes the tendency to cut into the flesh, while ensuring at the same time that the knots hold firmly. Chirlac threads are degraded in the body by a simple hydrolytic process. The degraded products are metabolized completely in the body. Absorption begins as a loss of tensile strength without appreciable loss of mass. 21 days after implantation appr. 50 % of its original tensile strength remains. All of the original tensile strength is lost by appr. 32 days after implantation. Absorption of Chirlac is essentially complete after 80-90 days.

Indications: Sterile Chirlac is designed for use in general soft tissue approximation and/or ligation, for the surgical adaptation of muscles and fasciae, for suturing of parenchymal organs, peripheral nerves, for ligatures of small vessels and for intradermal suturing.

Reaction in tissue: Slight initial inflammatory reaction in tissue.

Interaction: Sterile Chirlac should not be used in tissues which may undergo expansion, stretching or distension or which may require long-term mechanical support.

Polydox monofil is an absorbable, synthetic suture monofilament, made of p-Polydioxanon with excellent handling properties. The threads are available violet coloured. In tissue the thread indicates a slight initial inflammatory reaction. The Polydox threads are slowly degraded in the body by a simple hydrolytic process. Implantation studies show, that after 6 weeks the thread retains appr. 50 % of its origin tensile strength. The degraded products are completely metabolised by the body after 180-210 days. Indication: Sterile Polydox is designed for the use in general soft tissue approximation. These sutures are particularly useful where the combination of an absorbable and extended wound support is desirable (fasciae, orthopedics, vascular anastomosis).

Reaction in tissue: Slight initial inflammatory reaction in tissue.

Interaction: Sterile Polydox, being absorbable, should not be used where prolonged approximation of tissues under stress is required.
