<p>Gastrostomy feeding ports are disclosed which remain positively sealed after repeated and extensive use. In one embodiment, a valve housing (20) defines an inner passageway (29) to provide fluid communication into a long term indwelling catheter and includes a rigid compression collar portion (21) which defines a valve member receiving cavity (22) within the inner passageway (29). A resilient valve member (10) is compressively inserted within the receiving cavity (22), and defines a valve slit (16) which is normally biased closed when the valve member is inserted in the cavity. A right angle feeding adapter (60) is received through slit (16) to provide for enteral feeding, medication or pressure relief. 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 direct connection to a feeding tube adapter.</p> |
