A gastrostomy device that may be placed either endoscopically or percutaneously is disclosed. The catheter is a resilient tube with a resilient T-bar at one end. One wing of the T is provided with a pocket for the tip of an obturator rod. By inserting the rod in the pocket and orienting the rod along the tube, the bar is forced to a position in-line with the tube. The catheter may then be easily inserted into an established stoma. When the rod is removed, the bar returns to its orthogonal position, thereby retaining the catheter within the stomach. The device may be provided with a cup-shaped bolster whose mouth engages the skin about, but not adjacent to, the stoma to hold the bar snugly against the stomach wall. By providing the bolster with air vents, healing of the stoma is encouraged. By providing the device with two diametrically opposed pockets in the T-bar, a forked obturator may be used to fold both wings into a forward oriented, small axial cross section configuration for insertion into a stoma.

A catheter insertable into a passage through a wall using a rod having a tip, said catheter comprising: a resilient tube having a distal end, a central axis and a proximal end; a pair of resilient diametrically opposed, oppositely extending wings connected about the distal end; and a pocket in at least one of said wings, said pocket being spaced radially outward from the central axis of said tube and being adapted to receive the tip of the rod, whereby the pair of wings may be urged to a position collateral with the tube by inserting the tip in the pocket and orienting the rod collateral with the tube.
