A sealing structure for an elongate medical instrument. The sealing structure includes a first sealing member having a first body with oppositely facing first and second surfaces and a peripheral edge and a second sealing member having a second body with oppositely facing third and fourth surfaces and a peripheral edge. A housing has a peripheral wall to surroundingly engage the peripheral edges of the first and second bodies with the first and second sealing members in operative relationship, wherein the second surface on the first body facially abuts to the third surface on the second body. The first body has at least a first portion that is compressible and deformable, with the second body having at least a second portion that is likewise compressible and deformable. There is an opening in the first portion of the first body that extends through the first body from the first surface to the second surface. There is an opening in the second portion of the second body that extends through the second body from the third surface to the fourth surface. The openings in the first and second bodies are expandable to allow the first and second bodies to grippingly engage an elongate medical instrument extended through the openings in the first and second bodies with the first and second sealing members in operative relationship.
