Abstract
Abstract A low profile or skin level gastrostomy device for initial endoscopic placement in an incision provided through the stomach and abdominal walls of a patient has a collapsed resilient end portion packaged and compressed within a shroud that allows the end portion of the device positioned within the stomach to easily pass from the inner to the outer end of the incision. The shroud is pulled or pushed outwardly through the incision until the device is properly positioned therein. Subsequent to device placement, the shroud is removed and discarded, allowing the now external end portion of the device to expand to its normal position so as to engage the outer surface of the abdominal wall to maintain the device in position. Such a gastrostomy device package and method of placement avoid the need for establishing a fistulas stoma tract before placement of a low profile gastrostomy device, as is the usual case.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
99 words
A gastrostomy device package comprising: a gastrostomy device with a tubular midportion having an inner end providing an intragastric portion locatable in an internal cavity of a living body, and an outer end providing a collapsible external portion locatable at the outer surface of said living body, and a shroud means surrounding and enclosing said external portion to maintain said external portion in a collapsed condition within said shroud means, said shroud means being removable to allow said external portion to expand to a normal uncollapsed condition subsequent to the placement of the gastrostomy device in said living body.
Claim 2
Dependent Claim
99 words
A gastrostomy device package comprising: a gastrostomy device with a tubular midportion having an inner end providing an intragastric portion locatable in an internal cavity of a living body, and an outer end providing a collapsible external portion locatable at the outer surface of said living body, and a shroud means surrounding and enclosing said external portion to maintain said external portion in a collapsed condition within said shroud means, said shroud means being removable to allow said external portion to expand to a normal uncollapsed condition subsequent to the placement of the gastrostomy device in said living body.
Claim 3
Dependent Claim
23 words
A package according to claim 1, wherein the shroud means is elongated and has a distal end that is at least partially tapered.
Claim 4
Dependent Claim
16 words
A package according to claim 2, wherein said distal end is provided with a wire loop.
Claim 5
Dependent Claim
30 words
A package according to claim 2, wherein said distal end is provided with a longitudinal bore extending therethrough for receiving a guidewire along which said distal end can be moved.
Claim 6
Dependent Claim
17 words
A package according to claim 1, wherein said collapsed external portion is compressed within said shroud means.
Claim 7
Dependent Claim
16 words
A package according to claim 1, wherein said external portion is formed of resilient elastomeric material.
Claim 8
Dependent Claim
25 words
A package according to claim 1, wherein said shroud means includes a heat shrinkable plastic film material constituting a shrink-wrap package containing said external portion.
Claim 9
Dependent Claim
173 words
A gastrostomy device package comprising: a gastrostomy device with an elongated tubular midportion coaxially extending along a longitudinal axis, said midportion having an inner end providing an intragastric portion locatable in an internal cavity of a living body, and an outer end providing a collapsible external portion locatable at the outer surface of said living body, said external portion including at least two wing-like projections extending radially away from said axis when said external portion is in a normal uncollapsed condition; and a shroud means including a tubular sleeve of plastic film material surrounding and enclosing said external portion to maintain said external portion in a collapsed condition within said sleeve wherein said projections extend along lines generally parallel to said longitudinal axis so that the lateral extension of said external portion is reduced, said sleeve being removable to allow said projections to expand and extend radially away from said axis when said external portion is in a normal uncollapsed condition subsequent to the placement of the gastrostomy device in said living body.
Claim 10
Dependent Claim
173 words
A gastrostomy device package comprising: a gastrostomy device with an elongated tubular midportion coaxially extending along a longitudinal axis, said midportion having an inner end providing an intragastric portion locatable in an internal cavity of a living body, and an outer end providing a collapsible external portion locatable at the outer surface of said living body, said external portion including at least two wing-like projections extending radially away from said axis when said external portion is in a normal uncollapsed condition; and a shroud means including a tubular sleeve of plastic film material surrounding and enclosing said external portion to maintain said external portion in a collapsed condition within said sleeve wherein said projections extend along lines generally parallel to said longitudinal axis so that the lateral extension of said external portion is reduced, said sleeve being removable to allow said projections to expand and extend radially away from said axis when said external portion is in a normal uncollapsed condition subsequent to the placement of the gastrostomy device in said living body.
Claim 11
Dependent Claim
30 words
A package according to claim 8, wherein said projections are in adjacent, generally parallel relationship with each other when said external portion is in a collapsed condition within said sleeve.
Claim 12
Dependent Claim
20 words
A package according to claim 8, wherein said projections are diametrically opposed to each other relative to said longitudinal axis.
Claim 13
Dependent Claim
15 words
A package according to claim 8, wherein said projections are formed of resilient elastomeric material.
Claim 14
Independent Claim
164 words
A method of placing a gastrostomy device in a living body, comprising the steps of: providing an incision extending from the external surface of the body to an inner body cavity; positioning within said cavity a gastrostomy device with a tubular midportion having an inner end providing an intragastric portion, and an outer end providing a collapsible external portion, a shroud means surrounding and enclosing said external portion to maintain said external portion in a collapsed unexpanded condition within said shroud means; inserting the shroud means into said incision and moving the shroud means from the inner end of the incision out through the outer end thereof so as to position said tubular midportion within said incision with said intragastric portion remaining in said body cavity; and removing said shroud means to allow said external portion to expand to a normal uncollapsed condition so that the now expanded external portion engages the outer surface of the body to maintain the gastrostomy device in position.
Claim 15
Independent Claim
164 words
A method of placing a gastrostomy device in a living body, comprising the steps of: providing an incision extending from the external surface of the body to an inner body cavity; positioning within said cavity a gastrostomy device with a tubular midportion having an inner end providing an intragastric portion, and an outer end providing a collapsible external portion, a shroud means surrounding and enclosing said external portion to maintain said external portion in a collapsed unexpanded condition within said shroud means; inserting the shroud means into said incision and moving the shroud means from the inner end of the incision out through the outer end thereof so as to position said tubular midportion within said incision with said intragastric portion remaining in said body cavity; and removing said shroud means to allow said external portion to expand to a normal uncollapsed condition so that the now expanded external portion engages the outer surface of the body to maintain the gastrostomy device in position.
