1. A device for collection of fecal discharge, comprising:
a retaining component configured for deployment within a subject's rectum and having an annular cross-section, said annular cross-section of the retaining component forming a fluid inlet into an open end of a collection component affixed to said retaining component and forming a receptacle for matter discharged from a subject's rectum, wherein:
said retaining component comprising an annular body comprising a first material and a resilient ring comprising a second material, wherein the annular body overlays the resilient ring and forms an outer circumferential periphery of the retaining component, and wherein:
the resilient ring is configured to exert outward radial pressure of between 5 mmHg and 100 mmHg;
the thickness of the first material of the annular body between the resilient ring and the outer circumferential periphery of the retaining component is between 1 mm and 20 mm;
the first material and the second material have different flexural modulus, wherein the first flexural modulus of the first material is between 100 KPa and 100 MPa and the second flexural modulus of the second material is between 20 GPa and 210 GPa; and
the retaining component is collapsible in response to compression into at least one of:
a first collapsed state, wherein the retaining component is collapsed along two mutually perpendicular axes to form two peaks and two troughs; and
a second collapsed state, wherein the retaining component is collapsed along three axes, each arranged with 120 degrees between them, to form three peaks and three troughs.
