Method for percutaneously implanting a medical catheter and medical catheter implanting assembly
First Claim
1. A medical catheter implanting assembly comprising:
- (a) an outer sheath, said outer sheath having a proximal end and a distal end;
(b) an inner sheath, said inner sheath having a proximal end and a distal end, said inner sheath being slidably mounted in said outer sheath; and
(c) a medical catheter, said medical catheter having an internal bolster disposed at a distal end thereof, said medical catheter being inserted into said inner sheath, with said internal bolster being retained in a compressed state by said outer sheath;
(d) whereby sliding movement of said outer sheath relative to said inner sheath release said internal bolster from said compressed state.

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.
