Abstract
Abstract An apparatus for placing a feeding tube in a patient. The apparatus includes an introducer section defining a lumen therethrough and a tube section defining a lumen therethrough. A proximal end portion of the introducer section is mounted on a distal end portion of tube section such that the respective lumen are in fluid communication. Apertures are formed at the distal end of the introducer section and at the proximal portion of the tube section. The respective lumen are constructed to receive therein an endoscope. A graspable member is mounted on the distal end portion of the introducer section. A retaining member is mounted on the proximal end portion of the tube section. In order to place the apparatus in a patient, an endoscope is inserted into the aperture defined through the tube section and advanced such that a viewing portion of the endoscope is positioned proximal to the aperture defined through the distal end portion of the introducer section. The distal end portion of the introducer section is introduced into the patient's mouth and advanced through the patient's esophagus and into the patient's stomach. An incision is made through the patient's abdominal wall and into the patient's stomach. A grasping tool is inserted through the incision and is used to grasp the graspable member. The grasping tool and the apparatus are drawn through the incision until the retaining member engages the stomach. The endoscope remains in the patient's stomach as the apparatus of the present invention is drawn outwardly through the abdominal incision. The endoscope is then withdrawn from the patient's stomach through the patient's mouth.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
229 words
A method for placing a feeding tube in a patient, said method comprising: providing a feeding tube defining a lumen therethrough, said feeding tube having a distal end portion and a proximal end portion, a first aperture defined through said feeding tube at said distal end portion of said feeding tube, a second aperture defined through said feeding tube at said proximal end portion of said feeding tube, said first and second apertures providing fluid communication between said lumen defined through said feeding tube and an external environment of said feeding tube, said feeding tube having a graspable member on said distal end portion; providing an endoscope having a viewing portion; inserting said viewing portion of said endoscope into said lumen defined through said feeding tube; introducing said distal end portion of said feeding tube into a patient's mouth; advancing said distal end portion of said feeding tube through a patient's esophagus and into a patient's stomach; forming an incision through a patient's abdominal wall; advancing a grasping tool through said incision formed through a patient's abdominal wall; grasping said graspable member using said grasping tool; withdrawing said grasping tool from a patient's stomach and advancing said distal end portion of said feeding tube outwardly from a patient's stomach through said incision; and withdrawing said endoscope from a patient's stomach by pulling said endoscope outwardly through a patient's mouth.
Claim 2
Independent Claim
229 words
A method for placing a feeding tube in a patient, said method comprising: providing a feeding tube defining a lumen therethrough, said feeding tube having a distal end portion and a proximal end portion, a first aperture defined through said feeding tube at said distal end portion of said feeding tube, a second aperture defined through said feeding tube at said proximal end portion of said feeding tube, said first and second apertures providing fluid communication between said lumen defined through said feeding tube and an external environment of said feeding tube, said feeding tube having a graspable member on said distal end portion; providing an endoscope having a viewing portion; inserting said viewing portion of said endoscope into said lumen defined through said feeding tube; introducing said distal end portion of said feeding tube into a patient's mouth; advancing said distal end portion of said feeding tube through a patient's esophagus and into a patient's stomach; forming an incision through a patient's abdominal wall; advancing a grasping tool through said incision formed through a patient's abdominal wall; grasping said graspable member using said grasping tool; withdrawing said grasping tool from a patient's stomach and advancing said distal end portion of said feeding tube outwardly from a patient's stomach through said incision; and withdrawing said endoscope from a patient's stomach by pulling said endoscope outwardly through a patient's mouth.
Claim 3
Dependent Claim
37 words
A method in accordance with claim 1, wherein said method further comprises holding said endoscope substantially stationary while advancing said feeding tube apparatus outwardly through said incision, thereby exposing said endoscope from within said feeding tube apparatus.
Claim 4
Dependent Claim
31 words
A method in accordance with claim 1, wherein said distal end portion of said feeding tube apparatus is constructed of a polyurethane material having a hardness of substantially 60-90 Shore A.
Claim 5
Dependent Claim
30 words
A method in accordance with claim 1, wherein said proximal end portion of said feeding tube apparatus is constructed of a material having a hardness of substantially 30-70 Shore A.
Claim 6
Dependent Claim
42 words
A method in accordance with claim 1, wherein said method further comprises viewing a patient's esophagus with said viewing portion of said endoscope while advancing said distal end portion of said feeding tube through a patient's esophagus and into a patient's stomach.
Claim 7
Dependent Claim
32 words
A method in accordance with claim 1, wherein said method further comprises viewing a patient's stomach with said viewing portion of said endoscope prior to withdrawing said endoscope from a patient's stomach.
Claim 8
Dependent Claim
52 words
A method in accordance with claim 1, wherein said method further comprises inserting a needle into said incision through a patient's abdominal wall prior to advancing a grasping tool through said incision formed through a patient's abdominal wall, and wherein said grasping tool is advanced into a patient's stomach through said needle.
