1. A waste management appliance, comprising:
a tubular body having a proximal end and a distal end;
a cowl fastened to said tubular body at a first circumferential location in the vicinity of said proximal end, said cowl extending distally outside of said tubular body to a second circumferential location spaced distally from said first circumferential location, said cowl being fastened to said tubular body at said second circumferential location at a plurality of spaced positions around the circumference of said tubular body;
an inflatable balloon provided within said cowl; and
an inflation lumen having a proximal end opening to the interior of said balloon and extending distally towards the distal end of said tubular body;
wherein the cowl can be separated from said tubular body at a plurality of circumferential regions where the cowl is not fastened to the tubular body to form a plurality of pockets between the cowl and the uninflated balloon, and
the balloon can be inflated to a desired extent within the cowl by injecting a predetermined amount of fluid into said balloon via said lumen, the cowl functioning in the event of an attempt to inject more than said predetermined amount of fluid into said balloon to restrain inflation of said balloon beyond said desired extent.
