An access assembly including an anti-collapsing structure is provided. The access assembly includes a compressible body having first and second ends and a central portion extending therebetween. The compressible body defines at least a first lumen configured to receive an instrument in a sealing manner. The access assembly further includes an anti-collapsing structure extending at least partially between the proximal and distal ends of the compressible body. The anti-collapsing structure is configured to permit compression of the compressible body during insertion into an incision and return the compressible body to an uncompressed condition following insertion. |
