Sutura is the brand name of silk sutures manufactured by Dolphin Sutures. Silk sutures are entwined thread from silk worm larva. Silk sutures are coated and braided non-absorbable sutures. Silk sutures are specially treated with silicone to give strength and smoothen the surface which provides easy passage through tissues. Silk sutures are widely used as ligature and are also used for other applications like skin, ophthalmic, GI tract, etc. and are not indicated for use in biliary and urinary tract surgery. Silk sutures have moderate tissue reaction. Silk sutures are available in black colour.
