  • Surgical sponge and method of forming the same
    Patent number: 4068666
    Abstract: A surgical sponge or dressing having an absorbent core enclosed within first and second low-linting porous outer layers. The periphery of the core layer is wrapped within the fold of the reverted edge portion of the first outer layer, and the edge portion of the second outer layer is also reverted and is secured directly to the reverted edge portion of the first layer. The periphery of the core is thereby fully enclosed and the reverted edge portions of the outer layers result in a sponge or dressing having a relatively non-abrasive or atraumatic peripheral construction. The method of forming the improved sponge is also disclosed.
