Gastrostomy tube with improved internal retaining member
First Claim
1. A gastrostomy tube comprising:
- (a) a flexible tubular member, with a first end and a second end, and (b) a hollow energy-absorbing internal retaining member;
the internal retaining member having a foreshortened stem portion and a body portion;
the stem portion surrounding the first end of the tubular member and being sealingly attached thereto;
the body portion being substantially toroidal-like in form and substantially concentrically surrounding the stem portion and being connected thereto and having at least one drainage hole aperature formed therethrough radially outwardly from the stem portion;
the body portion having two stable resiliently reversible physical configurations, the toroidal-like form and a goblet-like form, the toroidal-like form being invaginatable to the goblet-like form and vice versa, the body portion when in toroidal-like form is concentric with and surrounds the stem portion and has a base wall curving out laterally beyond the first end of the tubular member and curling back towards itself to a rim which is disposed radially outwardly of the stem portion and defines a circular apperature which allows the body portion to be invaginated to the goblet-like form.

Abstract
An improved gastrostomy tube is a flexible tube having on one inner end thereof an improved energy absorbent internal retaining member which provides for less patient trauma during emplacement and subsequent percutaneous removal, while almost entirely avoiding either separation of the internal retaining member, i.e., the bumper, or its acute displacement. The energy absorbing internal retaining member has a hollow body portion with two resiliently reversible physical forms or shapes, toroidal-like, and, goblet-like connected to a foreshortened hollow axial stem portion that is attached to or integrally made with the inward end of the flexible tube. The internal retaining member is made in the toroidal-like form. During intentional removal, when under pressure against the stomach mucosa, the internal retaining member snaps into the unrolled, goblet-like shape and pulls smoothly out through the stoma tract.
