Endoscopic Forceps With Removable Handle
First Claim
1. A method comprising:
- advancing an endoscope into an internal surgical site;
advancing a first end of an elongate flexible body of a forceps through a tool channel of the endoscope into the site;
grasping a tissue with the first end of the forceps;
removing a proximal handle from a second end of the elongate body of the forceps;
retracting the endoscope out of the site over the elongate body while the forceps grasps the tissue;
replacing the handle on the forceps while the forceps grasps the tissue.

Abstract
An exemplary forceps system for use within a tool channel of an endoscope comprises an elongated body extending from a proximal end and a distal end having one or more internal lumens. An actuator is slidably positioned within a first lumen, and actuatable jaws are removeably coupled to a first end of the actuator near the distal end. A handle is removeably coupleable to the proximal end of the body, the removable handle having a forceps actuator operatively engageable with a second end of the actuator so as to control the actuatable jaws when the handle is coupled to the body. A single or double balloon closure device having an inflatable anchor on a peritoneal side and a narrow inflatable portion, is also provided. The narrow portion may be shaped to follow the shape of the transgastric cut. The balloon closure device may deliver medication speed up the healing process and may contain a biocompatible sealant that may be dispersed over the incision site and/or used to keep the anchor on the peritoneal side inflated.

16. A method of using forceps with a removable handle in natural orifice translumenal endoscopic surgery (NOTES), the method comprising:
-
creating a first port from a patient'"'"'s stomach into a peritoneal cavity; advancing an endoscope orally into the stomach, through the first port to an internal surgical site; advancing a first end of a forceps through a tool channel of the endoscope to the surgical site; engaging a tissue at the surgical site with the first end of the forceps; removing the handle from the forceps; retracting the endoscope out of the mouth, leaving the forceps in place; replacing the handle on the forceps; creating a second port from the stomach into a peritoneal cavity; advancing the endoscope orally into the stomach, through the second port into the peritoneal cavity to the internal surgical site; advancing a first end of a tool through the tool channel of the endoscope to the surgical site; manipulating the tissue at the internal surgical site with the forceps; and performing a procedure at the surgical site with the tool and forceps. - View Dependent Claims (17)

18. A balloon closure device for temporarily closing a transgastric tract comprising:
-
a delivery catheter having a proximal end and a distal end; an inflation lumen and a guide wire lumen within the catheter; and an inflatable closure balloon removeably coupled to the distal end, the balloon having a pressure valve in fluid communication with the inflation lumen such that the balloon remains inflated once uncoupled from the catheter, the balloon being sized to temporarily close the transgastric tract when inflated. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A method of closing a transgastric tract, the method comprising:
-
advancing a closure device delivery catheter to the transgastric tract by means of a guide wire or endoscope; positioning an inflatable balloon closure device on a first end of the closure device across the transgastric tract; and inflating the balloon to seal the transgastric tract. - View Dependent Claims (28, 29, 30, 31)

32. A transluminal crossing device comprising:
-
an elongated flexible body extending from a proximal end to a distal end; a tissue penetrating tip disposed at the distal end so as to form a penetration of a wall of a body lumen; and an expandable structure disposed proximally of the tip, the expandable structure having a small-profile configuration suitable for advancement of the expandable structure into the penetration and a large-profile configuration, expansion of the expandable structure from the small-profile configuration to the large profile configuration suitable for expanding the penetration when the wall surrounds the expandable structure. - View Dependent Claims (33)
