Abstract

A method for percutaneously implanting a medical catheter, such as a gastrostomy feeding tube, and a medical catheter implanting assembly. In one embodiment, the implanting assembly includes a gastrostomy feeding tube, an inner sheath and an outer sheath. The feeding tube has an internal bolster integrally formed at its distal end. The inner sheath includes a bore extending distally from its proximal end to a point prior to its distal end and a transverse window communicating with the bore. The outer sheath includes a proximal end, a distal end and a longitudinal bore. The outer sheath is inserted over the inner sheath, and the feeding tube is inserted into the inner sheath, with the internal bolster being folded and tucked into the window and retained therein by the outer sheath. Movement of the outer sheath relative to the inner sheath to expose the window allows the bolster to decompress.
