  • Surgical fabric with printed X-ray marker
    Patent number: 5045080
    Abstract: Woven and nonwoven fabrics for use in surgical procedures are printed with a radiopaque polymeric composition which bonds to the surface of the fabric. The composition is applied in a visually distinctive pattern, or may assume the pattern of the underlying fabric. The polymeric composition is readily recognized in an X-ray image and provides an improved means for detecting a surgical sponge inadvertently left in a patient. Preferred compositions are latex or plastisols of a printable viscosity containing from 15 to 70% by weight BaSO.sub.4 having a particle size greater than about 5 microns.

  • Radiopaque polymeric composition
    Patent number: 4935019
