| Description | Absorbable biological suture material. Plain is an absorbable suture made by twisting together strands of purified collagen taken from bovine intestines. The natural plain thread is precision ground in order to achieve a monofilament character and treated with a glycerol containing solution. Plain is absorbed by enzymatic degradation. | Absorbable biological suture material. Chromic is an absorbable suture made by twisting together strands of purified collagen taken from bovine intestines. Due to undergoing a ribbon stage chromicisation (treatment with chromic acid salts), the chromic offers roughly twice the stitch-holding time of plain catgut. The natural chromic thread is precision ground in order to achieve a monofilament character and treated with a glycerol containing solution. Chromic is absorbed by enzymatic degradation. Note – catgut is no longer used in the UK for human surgery. | It is a synthetic absorbable suture material. Braided synthetic absorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. | It is a synthetic absorbable suture material. Monofilament synthetic absorbable suture, prepared from the polyester, poly (p-dioxanone). |
