Abstract
Abstract A shim device is provided for use with a low profile gastrostomy device having a gastrostomy tube fitted in a mature stoma and held in place between an internal retention mechanism disposed within a visceral organ of a patient and an external retention mechanism seated on the outer abdominal wall of a patient. Further, the shim device provides an adjustable shim body which is inserted between the external retention mechanism and the patient for accommodating the gradual growth of the patient during convalescence. The shim device also operates to evenly distribute the weight of the low profile gastrostomy device over a patient's outer body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
153 words
A shim device comprising: a shim body having opposed sides, said shim body including an inner portion having an axial opening formed therethrough, said shim body further including at least one outer portion defining an outer edge radially extending outwardly from said inner portion, said at least one outer portion having a radial slit formed therethrough; a first plurality of support pads formed on one of said opposed sides and extending a first height; and a second plurality of support pads formed on the other of said opposed sides and extending a second height therefrom, said first plurality of support pads formed on one of said opposed sides mirroring the second plurality of support pads on the other of said opposed sides, wherein either one of said first or second plurality of support pads provides a base and the other of said first or second plurality of support pads provides a support surface.
Claim 2
Dependent Claim
153 words
A shim device comprising: a shim body having opposed sides, said shim body including an inner portion having an axial opening formed therethrough, said shim body further including at least one outer portion defining an outer edge radially extending outwardly from said inner portion, said at least one outer portion having a radial slit formed therethrough; a first plurality of support pads formed on one of said opposed sides and extending a first height; and a second plurality of support pads formed on the other of said opposed sides and extending a second height therefrom, said first plurality of support pads formed on one of said opposed sides mirroring the second plurality of support pads on the other of said opposed sides, wherein either one of said first or second plurality of support pads provides a base and the other of said first or second plurality of support pads provides a support surface.
Claim 3
Dependent Claim

Claim 7
Dependent Claim
21 words
A shim device according to claim 1 , wherein said radial slit extends between said axial opening and said outer edge.
Claim 8
Dependent Claim
58 words
A shim device according to claim 1 , wherein said first plurality and said second plurality of support pads each include a plurality of outer pads proximate said outer edge, and wherein said first plurality and said second plurality of support pads each include a plurality of inner pads disposed on said inner portion proximate said axial opening.
Claim 9
Dependent Claim
54 words
A shim device according to claim 2 , wherein said first plurality and said second plurality of support pads each include a plurality of outer pads proximate said outer edge, and wherein said first plurality and said second plurality of support pads each include a plurality of inner pads disposed proximate said axial opening.
Claim 10
Dependent Claim
24 words

Claim 13
Independent Claim
247 words
A method for attaching a shim device to a gastrostomy device, said gastrostomy tube comprising a retention member, said retention member including a plurality of legs that extend therefrom, said method comprising the steps of: (a) providing a shim device comprising a shim body having opposed sides, said shim body including an inner portion having an axial opening formed therethrough, said shim body further including at least one outer portion defining an outer edge radially extending outwardly from said inner portion, said at least one outer portion having a radial slit formed therethrough, a first plurality of support pads formed on one of said opposed sides and extending a first height, a second plurality of support pads formed on the other of said opposed sides and extending a second height therefrom, said first plurality of support pads formed on one of said opposed sides mirroring the second plurality of support pads on the other of said opposed sides; (b) determining which of said opposed sides is to engage said legs and which other of said opposed sides is to provide a base; (c) orienting said shim device towards one of said opposed sides; (d) spreading said slit such that said tubular member may be passed therethrough; (e) lifting the legs of the retention member; (f) passing said tubular member through said slit and into said axial opening; and (g) positioning the shim device such that the legs are seated between said outer legs and said inner pads.
Claim 14
Independent Claim
247 words
A method for attaching a shim device to a gastrostomy device, said gastrostomy tube comprising a retention member, said retention member including a plurality of legs that extend therefrom, said method comprising the steps of: (a) providing a shim device comprising a shim body having opposed sides, said shim body including an inner portion having an axial opening formed therethrough, said shim body further including at least one outer portion defining an outer edge radially extending outwardly from said inner portion, said at least one outer portion having a radial slit formed therethrough, a first plurality of support pads formed on one of said opposed sides and extending a first height, a second plurality of support pads formed on the other of said opposed sides and extending a second height therefrom, said first plurality of support pads formed on one of said opposed sides mirroring the second plurality of support pads on the other of said opposed sides; (b) determining which of said opposed sides is to engage said legs and which other of said opposed sides is to provide a base; (c) orienting said shim device towards one of said opposed sides; (d) spreading said slit such that said tubular member may be passed therethrough; (e) lifting the legs of the retention member; (f) passing said tubular member through said slit and into said axial opening; and (g) positioning the shim device such that the legs are seated between said outer legs and said inner pads.
Claim 15
Dependent Claim
42 words
A method for attaching a shim device to gastrostomy tube according to claim 12 , wherein said step of lifting the legs of the retention member further comprises lifting the legs with the user's hand gripped between a user's thumb and forefinger.
