ABSTRACT:
An enteral feeding catheter is characterized by being adapted for introduction through the mouth via a guidewire that extends from the mouth through the esophagus, stomach and abdominal puncture. The catheter has a relatively stiff leading portion of length sufficient to extend along the guidewire from the mouth through the abdominal puncture and of stiffness sufficient to permit it to be pushed along the guidewire, at least an initial length of the catheter being tapered to a narrow leading tip to enable the puncture to be dilated as its drawn therethrough. The catheter also has a relatively soft, large diameter trailing portion connected to the leading portion adapted to be drawn along said guidewire by grasping and pulling the stiff leading portion until the leading end of the soft portion extends outside the body through the widened puncture, while the trailing end remains in the stomach, whereby the relatively soft trailing portion can serve as a conduit for enteric feeding. A method of placing the device for enteral feeding is described, as is a retractable locking device of special configuration for use with the soft portion of this catheter, or others, the lock providing a relatively large, compared to the opening in an associated retainer, fixed protuberance about the catheter to prevent passage of the catheter through the opening absent application of abnormally high pulling force.
