Percutaneous gastrostomy feeding tube applicator and method.
First Claim
1. A gastrostomy method for making a channel through a patient'"'"'s stomach wall and abdomen wall for receiving a suture strand with first and second ends and for receiving a feeding tube, the gastrostomy method comprising the steps of:
- directing an elongated gastrostomy device through the patient'"'"'s esophagus and into the stomach, the device having a proximal region and a distal region, lying at an obtuse angle within the range of 130°
to 150°
to the proximal region for placement in the stomach, an opposing proximal region for placement outside the esophagus for access by the surgeon, a removable needle near the distal region for piercing the channel, and a shield means for covering the needle when it is being directed through the esophagus,placing the needle in a desired location near the stomach wall by manipulating the proximal region of the device,remotely actuating the shield means to unshield the needle,remotely actuating the needle to move forward to make the channel by piercing through the stomach wall and abdomen wall to extend outside the patient'"'"'s body.

Abstract
Various embodiments of a gastrostomy method and applicator device are shown and described. The gastrostomy device has an elongated body for insertion into the patient'"'"'s stomach, a removable for piercing a channel through the stomach and abdomen walls, a shield means for removably covering the needle as it is inserted into the stomach, and an actuating means for moving the needle forward to pierce the channel. The gastrostomy method includes piercing the channel from the inside of the stomach to the outside of the patient'"'"'s body. The method includes insertion of the invented device into the stomach, placement of the needle, unshielding the needle, and actuating the needle to pierce the channel. Optionally, the method may include steps of drawing a strand through the channel and out the mouth, attachment to a feeding tube, and drawing the feeding tube into the stomach and into the channel.

10. A gastrostomy device for making a channel through a patient'"'"'s stomach wall and abdomen wall for receiving a suture strand and a feeding tube, the gastrostomy device comprising:
-
an elongated body having a distal region and an opposing proximal region, with the distal region lying at an obtuse angle within the range of 130°
to 150°
to the proximal region the distal region for placement through the patient'"'"'s esophagus into the stomach and the proximal region for extending out of the esophagus for access by the surgeon,a removable needle attached to the elongated body distal region for making the channel by piercing through the stomach wall and abdomen wall to extend outside the patient'"'"'s body, a retractable shield means for covering the needle when the distal region is moved through the esophagus and for being remotely retracted to uncover the needle, an actuating means accessible from outside the esophagus for remotely moving the needle forward to pierce the channel. - View Dependent Claims (11, 12, 13, 14, 15)

16. A gastrostomy device for making a channel through a patient'"'"'s stomach wall and abdomen wall for receiving a suture strand and a feeding tube, the gastrostomy device consisting of:
-
an elongated probe having a proximal region and an opposing distal region, lying at an obtuse angle within the range of 130°
to 150°
to the proximal region having a blunt end for tapping against the stomach wall,an elongated rod extending generally parallel to and slidably connected to the probe and having a proximal region and an opposing distal region, a removable needle attached to the distal region of the rod for making the channel by piercing through the stomach wall and abdomen wall to extend outside the patient'"'"'s body, a retractable shield means for covering the needle when the distal region is moved through the esophagus and for being remotely retracted to uncover the needle, and an actuating means accessible from outside the esophagus for remotely moving the needle forward to pierce the channel. - View Dependent Claims (17, 18, 19)
