Abstract
Abstract A nonabsorbent holding member adapted for use within an abdominal cavity of a patient defined by an anterior wall, a posterior wall and two lateral walls to keep the patient's bowels out of the operative field during open pelvic surgery. The holding member has a peripheral edge formed of a resiliently deformable material sized to be received within the abdominal cavity. The resilient deformation of at least a portion of the peripheral edge of the holding member results in a residual reactive force against the abdominal cavity to assist in positioning the holding member in the abdominal cavity.
