Apparatus and method for placement of a percutaneous endoscopic gastrostomy tube
First Claim
1. A method for placing a feeding tube in a patient, said method comprising the steps of:
- providing a placement wire dispenser including a rotatable placement wire receptacle and a tube extending outwardly from said placement wire receptacle, said placement wire receptacle defining a placement wire receptacle outlet, said tube defining a placement wire tube inlet, said placement wire receptacle outlet and said placement wire tube inlet disposed in communication with one another, a placement wire wound about said placement wire receptacle, said placement wire being in mechanical engagement with said placement wire receptacle whereby rotation of said placement wire receptacle advances a first end portion of said placement wire through said placement wire receptacle outlet and through said tube, said tube having a first end constructed for insertion through a patient'"'"'s abdominal wall and into a patient'"'"'s stomach;
placing said first end of said tube through a patient'"'"'s abdominal wall and into a patient'"'"'s stomach;
imparting rotational movement to said placement wire receptacle to advance the first end portion of said placement wire from said placement wire receptacle, through said placement wire receptacle outlet, through said placement wire tube inlet, through said tube, and into a patient'"'"'s stomach;
grasping the first end portion of said placement wire using a grasping tool inserted through a patient'"'"'s mouth;
withdrawing the first end portion of said placement wire through a patient'"'"'s mouth using the grasping tool;
removing the first end of said tube from a patient'"'"'s abdominal wall;
engaging a first end portion of a feeding tube on the first end portion of said placement wire; and
urging said feeding tube through a patient'"'"'s mouth and stomach using said placement wire until the first end portion of said feeding tube passes percutaneously through a patient'"'"'s abdominal wall.

Abstract
A method for placing a feeding tube placement wire in a patient. The method includes the step of providing a placement wire dispenser. The dispenser includes a rotatable placement wire receptacle that defines a placement wire outlet. The dispenser further includes a tube extending outwardly from the placement wire receptacle. The tube defines a placement wire inlet that is in communication with the placement wire outlet of the receptacle. A placement wire is wound about the receptacle, and is in mechanical engagement with the receptacle, such that rotation of the placement wire receptacle causes a first end of the placement wire to be advanced through the placement wire outlet, through the placement wire inlet of the tube, and through the tube. A first end of the tube is constructed for insertion through a patient'"'"'s abdominal wall and into a patient'"'"'s stomach. The method further includes the step of placing the first end of the tube through a patient'"'"'s abdominal wall and into a patient'"'"'s stomach. Rotational movement is imparted to the receptacle so as to advance the placement wire through the placement wire outlet, through the placement wire inlet, through the tube, and into a patient'"'"'s stomach.
