Abstract
An absorbable fabric which effectively reduces the incidence of postoperative adhesions when used as a physical barrier at the operative site is a warp knit fabric of oxidized regenerated cellulose or other bioresorbable material. The barrier fabric is particulary characterized by having a density of 8 to 15 mg/cm.sup.2 and an open area porosity of 12 to 20 percent.
Claims14
A method for reducing the incidence of postoperative adhesions which comprises positioning as a physical barrier between the site of the surgical activity and neighboring tissue a fabric constructed of a bioresorbable material, said fabric being characterized by having a density of 8.0 to 15 mg/cm.sup.2 and a porosity of 12 to 20 percent open area.
A method for reducing the incidence of postoperative adhesions which comprises positioning as a physical barrier between the site of the surgical activity and neighboring tissue a warp knit fabric of oxidized regenerated cellulose, said fabric being characterized by having a density of 8.0 to 15 mg/cm.sup.2 and a porosity of 12 to 20% open area.
A method for reducing the incidence of postoperative adhesions which comprises positioning as a physical barrier between the site of the surgical activity and neighboring tissue a warp knit tricot fabric of oxidized regenerated cellulose, said fabric being characterized by a density of 9 to 13 mg/cm.sup.2 and an open area porosity of 15 to 19 percent.
