Gastrostomy feeding ports are disclosed which remain positively sealed after repeated and extensive use. In one embodiment, a valve housing defines an inner passageway to provide fluid communication into a long term indwelling catheter and includes a rigid compression collar portion which defines a valve member receiving cavity within the inner passageway. The resilient valve member has an outer peripheral edge which generally conforms in shape to the valve member receiving cavity but is larger in dimension than the cavity when uncompressed. The resilient valve member also includes an outer wall portion which extends away from the outer peripheral edge of the diaphragm portion and which generally conforms in shape to the cavity. The resilient valve member is compressively fitted within the receiving cavity by the advancing of the outer wall portion into said cavity to thereby cause the outer peripheral edge to be compressed in dimension to fit within the cavity, with the compression collar pressing inwardly against the outer peripheral edge of the diaphragm portion to apply laterally compressive forces which bias the slit toward a normally closed position. Additional embodiments are disclosed which provide for the direct conversion of an implanted PEG tube into a low profile feeding port, and which further provide for the direct secure connection to an enteral feeding tube adapter.

[ What is claimed is:] [1.] A gastrostomy feeding port for direct sealing connection to an enteral feeding tube adapter having a front stem portion and a base stem portion, comprising:a port head defining a top opening configured to allow the front stem portion of the enteral feeding tube adapter to pass therethrough, said top opening being configured to seal about the base stem portion of the adapter;a tube opening configured to seal about the front stem portion of the adapter passing through said top opening;a one-way entrance valve secured within said port head between said top opening and said tube opening and aligned therewith, said valve opening to permit the adapter to pass therethrough, and said valve closing when the adapter is removed.
