摘要： The present disclosure provides a composite surgical seal for use in a surgical access device which defines an access channel through it and includes a seal member configured and dimensioned to form a seal with a housing interior wall of a surgical access device. The seal member includes a layer defining an orifice therethrough and a fabric layer substantially encapsulating the resilient layer such that a surface of the resilient layer which defines the orifice is covered by the fabric layer. The access channel is configured and dimensioned such that insertion of a surgical instrument into the access channel causes the seal member to form a substantial sealing relation with the surgical instrument inserted therethrough. A method of forming a composite surgical seal in accordance with the present disclosure is also provided herewith.
