Abstract
Abstract A catheter or ostomy tube placement tip is comprised of a tapered, substantially conical head portion and a cylindrical body or stem portion centrally attached to the base thereof. The cylindrical base fits snugly within the lumen of a catheter or ostomy tube such as a ostomy or jejunal feeding tube and its tapered design allows for the insertion and placement of the tube within the lumen of the stomach or other body cavity through an opening or ostomy. Once properly placed, the tip is discharged from the end of the tube so that it is dissolved by human body fluids and is excreted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A method for the insertion of a gastrostomy or jejunal feeding tube into an ostomy of a patient comprising the attachment of a placement tip comprising a substantially tapered head portion comprising a planar base and a substantially cylindrical body portion substantially perpendicular to the base to the end of a gastrostomy or jejunal feeding tube by inserting the body portion of said tip into the end of said tube to plug said tube, placing the tip against the ostomy of said patient and applying pressure on the tube against the patients body until the attached tip dilates the ostomy so as to allow for the entry of the tube into the ostomy, and thereafter exerting fluid pressure into the tube and detaching the tip inside the patient.
Claim 2
Independent Claim
128 words
A method for the insertion of a gastrostomy or jejunal feeding tube into an ostomy of a patient comprising the attachment of a placement tip comprising a substantially tapered head portion comprising a planar base and a substantially cylindrical body portion substantially perpendicular to the base to the end of a gastrostomy or jejunal feeding tube by inserting the body portion of said tip into the end of said tube to plug said tube, placing the tip against the ostomy of said patient and applying pressure on the tube against the patients body until the attached tip dilates the ostomy so as to allow for the entry of the tube into the ostomy, and thereafter exerting fluid pressure into the tube and detaching the tip inside the patient.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein said tip and associated feeding tube are pressed downward into the lumen of the stomach or small intestine.
Claim 4
Dependent Claim
40 words
The method of claim 2 wherein said tip is detached from the lumen of the gastrostomy tube after insertion so that both the conical head and cylindrical base portions are expelled into the patient's gastro-intestinal system for digestion and/or excretion.
Claim 5
Dependent Claim
216 words
A detachable placement tip for the insertion of a catheter or ostomy tube into a patient; said tip comprised of a soluble or digestible material selected from the group consisting of cellulose and its derivatives, starch and its derivatives, amylose, amylopectin, pectin, guar gum, xanthan gum, acacia gum, and mixtures thereof; said tip comprising a substantially tapered head portion comprising a planar base and a body portion substantially perpendicular to the base for engaging the inner walls and plugging the end of the catheter or ostomy tube to which the tip is detachably attached; wherein said tapered head is configured to dilate the opening of the ostomy when said tube is placed therein; and further comprises a cylindrical skirt about the periphery of the base of said head portion; wherein said body portion is comprised of more than one substantially cylindrical stems that are insertable within the hollow lumen of a multi-lumen catheter or ostomy tube prior to placing said tube within a surgically incised ostomy; wherein a circular well is formed between said skirt and said body portion for receiving said catheter or ostomy tube when said body is inserted within the lumen of said catheter or ostomy tube; said body portion being readily removable by fluid pressure from within the lumen of the tube.
Claim 6
Dependent Claim
216 words
A detachable placement tip for the insertion of a catheter or ostomy tube into a patient; said tip comprised of a soluble or digestible material selected from the group consisting of cellulose and its derivatives, starch and its derivatives, amylose, amylopectin, pectin, guar gum, xanthan gum, acacia gum, and mixtures thereof; said tip comprising a substantially tapered head portion comprising a planar base and a body portion substantially perpendicular to the base for engaging the inner walls and plugging the end of the catheter or ostomy tube to which the tip is detachably attached; wherein said tapered head is configured to dilate the opening of the ostomy when said tube is placed therein; and further comprises a cylindrical skirt about the periphery of the base of said head portion; wherein said body portion is comprised of more than one substantially cylindrical stems that are insertable within the hollow lumen of a multi-lumen catheter or ostomy tube prior to placing said tube within a surgically incised ostomy; wherein a circular well is formed between said skirt and said body portion for receiving said catheter or ostomy tube when said body is inserted within the lumen of said catheter or ostomy tube; said body portion being readily removable by fluid pressure from within the lumen of the tube.
Claim 7
Dependent Claim
24 words
The placement tip of claim 4 wherein said cylindrical stems may be inserted into the lumens of more than one catheter or ostomy tube.
