Gastrostomy device package and method of assembly
First Claim
1. A percutaneous gastrostomy device comprising:
- a tubular portion having a distal end;
an internal bolster secured to said distal end, said internal bolster having a radial wing secured to said tubular portion, said internal bolster being flexible to permit elastic deformation between a first orientation generally aligned with said longitudinal axis, with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfuried and extending generally transverse to said tubular portion longitudinal axis, said wing including a pocket;
a rod member, a projecting end and a handle, said rod member having a hollow tube along its logitudinal axis, said rod member being removably received within said tubular portion and said projecting end being removably received within said pocket of said internal bolster; and
a constraining member encasing said internal bolster to retain said internal bolster in said first orientation, with said wing wrapped into said generally cylindrical configuration and to cover at least a major portion of said wrapped wing, said constraining member having a ripcord attached thereto for tearing said constraining member and deploying said internal bolster, allowing said internal bolster to move from said first orientation to said second orientation.

Abstract
A gastrostomy device includes a tubular portion and an internal bolster having a radial wing secured to the tubular portion. The internal bolster is flexible and permits elastic deformation between a first orientation with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfuried. A constraining member encases the internal bolster to retain the internal bolster in the first orientation and to cover at least a major portion of the wrapped wing. Removal of the casing permits the internal bolster to move from the first orientation to the second orientation. The internal bolster may be deployed by a ripcord, freeing the internal bolster into the patient'"'"' stomach and deploying the internal bolster to the second orientation. Alternatively, the internal bolster may be deployed by the constraining member being dissolved by the patient'"'"'s bodily fluids located inside the patient'"'"'s stomach.

8. A percutaneous gastrostomy device comprising:
-
a tubular portion defining a longitudinal axis;
an internal bolster having a single radial wing secured to said tubular portion, said internal bolster being flexible to permit elastic deformation between a first orientation generally aligned with said longitudinal axis, with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfuried and extending generally transverse to said tubular portion longitudinal axis; and
a constraining member encasing said internal bolster to retain said internal bolster in said first orientation, with said wing wrapped into said generally cylindrical configuration, and to cover at least a major portion of said wrapped wing, wherein the removal of said constraining member permits the internal bolster to move from said first orientation to said second orientation, wherein the constraining member encasing said internal bolster is in the form of a capsule, and wherein said capsule is made of a material dissolvable in the patient'"'"'s stomach.

9. A percutaneous gastrostomy device comprising:
-
a tubular portion defining a longitudinal axis;
an internal bolster having a single radial wing secured to said tubular portion, said internal bolster being flexible to permit elastic deformation between a first orientation generally aligned with said longitudinal axis, with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfuried and extending generally transverse to said tubular portion longitudinal axis; and
a constraining member encasing said internal bolster to retain said internal bolster in said first orientation, with said wing wrapped into said generally cylindrical configuration, and to cover at least a major portion of said wrapped wing, wherein the removal of said constraining member permits the internal bolster to move from said first orientation to said second orientation, wherein a locking ring is positioned medially along the tubular portion, and sized to frictionally engage the tubular portion, and slidably mounted there along, and adjustable solely by frictional engagement with the tubular portion to accommodate to the size of the wearer, the locking ring providing a plurality of perforations and spaced ridges to enable air circulation between the locking ring and the body.
