Abstract
Abstract A stoma measuring device is provided comprising a valve housing containing a valve, a lumen with a port located near its distal end, with the lumen having its proximal end secured to the valve housing, and an inflatable component member, with this member located near the distal end of the lumen, the member having a first end secured to the lumen intermediary the port and the valve housing. The lumen is relatively flexible and may be fabricated with a radiopaque filler. The method for using the device of this invention permits the measuring of the depth of a stoma by inserting the distal end of a lumen through the opening in the stomach, the lumen having a port near the distal end, the lumen also secured to the first end of an inflatable component member, the port being intermediary the first end and the distal end, the lumen also having indicia thereon, inflating the member and ascertaining the relative distance between the first end in the stomach and the outer layer of skin through the use of the indicia. Additional steps in the method may include keeping the member inflated by use of a valve until the distance is ascertained and deflating the member following ascertaining their distance so as to permit the lumen to be withdrawn through the stoma.
