Abstract
A nonabsorbent monolithic holding member having a plurality of openings to define spring segments and columns adapted for use within an abdominal cavity of a patient 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 in combination with the spring segments and columns results in a predetermined residual reactive force against the abdominal cavity to assist in positioning the holding member in the abdominal cavity while resisting movement of the retracted intestines though the deformed openings.
Claims21
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:
- a holding member adapted to be received in the patient's abdominal cavity and having an edge fabricated from foam, and
- at least one opening in said holding member not in communication with said edge.
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:
- a monolithic holding member fabricated from a material and adapted to be received in the patient's abdominal cavity and having an edge and a core, wherein said material of said core has a higher density than said edge;
- and
- at least one opening in said holding member not in communication with said edge.
Apparatus adapted for use within an abdominal cavity of a patient, said cavity being defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:
- a monolithic holding member adapted to be received in the patient's abdominal cavity having an edge fabricated from foam and having a core, and
- at least one opening in said holding member not in communication with said edge to define a spring segment.
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:
- a holding member adapted to be received in the patient's abdominal cavity and having an edge formed of a deformable polymer, said holding member having a compressed core fabricated by application of heat and pressure to a portion of said holding member, and
- at least one opening in said holding member not in communication with said edge.
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:
- a holding member adapted to be received in the patient's abdominal cavity and having an edge formed of a deformable polymer, a plurality of elongated openings are disposed adjacent said edge of said holding member, said openings define spring segments and columns, and
- at least one opening in said holding member not in communication with said edge.
