Method of assembling a percutaneous gastrostomy device
First Claim
1. An assembly method for a percutaneous gastrostomy device comprising:
- providing a tubular portion having a distal end and a proximal end;
securing an internal bolster to the distal end of the tubular portion, the internal bolster having a pocket provided thereon;
folding the internal bolster around the distal end of the tubular portion; and
encasing the folded internal bolster with a dissolvable constraining member to retain the internal bolster into the folded position; and
threading a ripcord through the tubular portion, through a bolster opening, through the pocket of the internal bolster, and through the dissolvable constraining member.

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 unfurled. 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.
