ABSTRACT:
A gastrostomy device having an external inflationary indicator is disclosed which comprises an external retention member having a tubular member extending therefrom for providing a fluid pathway to a patient's gastrointestinal tract. The external retention member includes a fluid conduit in communication with a inflationary lumen for providing fluid to inflate a balloon member attached to the tubular member. The inflationary indicator includes a thin wall section of the external retention member which forms a flexible membrane that defines first and second portions divided by a separating bar. The flexible membrane assumes a convex shape when the balloon member is in an inflated condition, while it assumes a concave shape when in the deflated condition. The shape in shape of the flexible membrane provides the user with a visual and tactile indication as to the inflationary state of the balloon member.
