Abstract
A tubular prosthesis comprising a tube having an inner end securable deeply within an outwardly-open body opening and an outer end affixed to a mounting plate. The outer tube end may be everted upon a circumferentially positioned rigid ring, the thus enlarged tube end bearing against an orifice formed in the mounting plate. A forwardly-facing bore formed in the plate coaxial with the orifice is sized to snugly receive the enlarged end of the tube. A disclosed embodiment utilizes a pair of tubes coaxially joined within the bore of the plate, one tube end being everted upon a rigid supporting ring and the everted end being received within the open adjacent end of the outermost tube. The plate may have securing means for holding the outer tube in a sealed, folded back orientation.
