Surgical Sutures Types
1. Chromatic Catgut
- Animal originated suture with twisted filament, absorbable brown color and green color.
- Tissue reactivity is relatively moderate.
- Absorbed by enzymatic in approximately 90 days

2. Plain Catgut
- Absorbable, animal originated suture with twisted multifilament, beige color.
- Tissue reactivity is relatively moderate.
- Absorbed by enzymatic in approximately 70 days

3. Silk Braided
- Natural, multifilament, braided, non-absorbable, silk suture, color black, white.
- Tissue reaction may be moderate

4. Polyester Braided
Synthetic, non-absorbable, multifilament, braided suture, color green, Because of its non-absorbable synthetic origin, it has a minimum tissue reactivity.

5. Nylon Monofilament
- Monofilament, synthetic, non-absorbable suture, color black, blue or undyed.
- Tissue reaction is minimal.
- Nylon is a non-absorbable material that with time, is encapsulated by connective tissue.

6. Polypropylene Monofilament
- Synthetic, non-absorbable, monofilament suture, color blue
- Tissue reaction is minimal.

7. PGA
- Synthetic, absorbable, mutifilament braided suture, in a violet color or undyed, The tissue reactivity in microscope form is minimal.
- Absorption occurs through progressive hydrolytic action, completed between 60 or 90 days.
- Be sterilized by EO.
- Package: Individual aluminum sealed foil
