1. A method of using a collector for fecal discharge, the method comprising:
inserting the collector within a subject's rectum while an annular component of the collector is in a compressed configuration, the annular component having a proximal end and a distal end, wherein the proximal end is situated more proximal to the subject's anal opening than the distal end; and
causing the annular component to expand to an expanded configuration within the subject's rectum such that the annular component exerts an outwardly directed radial pressure against the subject's rectal walls, wherein the collector is configured to direct the fecal discharge toward an outlet of the collector, the annular component comprising a plurality of adjacent arms connected in an undulating pattern forming a series of peaks and troughs around a lumen of the annular component, wherein the arms impel the annular component from the compressed configuration toward the expanded configuration, wherein the collector comprises a flexible tubular sheath having a first open end in connection with the proximal end of the annular component and a second open end providing an outlet for the fecal discharge.
