This invention refers to a flexible morpho -anatomical (1) mesh intended to be introduced into a vaginal or rectal cavity (40,50) of a human or animal,Provided with means of removal (4) from the vaginal or rectal cavity (40, 50),Having that mesh (1) a proximal end corresponding to that part of the mesh (1) which first comes into contact with that cavity (40,50) and a distal end,Which corresponds to the part of the mesh (1) which finally enters that cavity (40,50) and that mesh (1) comprising two overlapping sheets (16,17),At least partially,Defining an overlay area,Where the said first and second leaves (16,17) are attached to each other by at least two restraint elements (11, 12, 13),Defining at least one bag (10) inside the overlapping area to contain a substance (60),And in which the said mesh (1) additionally comprises at least one blocking element (20) to retain an applicator (30) in a substantially fixed position in relation to the mesh (1),Having at least one blocking element (20) which is perpendicular to the direction of insertion of the mesh (1) into the vaginal or rectal cavity (40,50),Preferably that blocking side (22) is situated below the opening of the stock exchange (10) in such a way that part of the mesh can fold to close the gap completely. This invention also refers to the use of mesh (1) for the retention of bodily fluids from such cavities or for delivery of a substance such as microbial gel (e.G. Anti -hiv microbicide),Or a probiotic or both.a presente invenção refere-se a uma malha morfo-anatômica flexível (1) destinada a ser introduzida em uma cavidade vaginal ou retal (40,50) de um ser humano ou animal, sendo provida de meios de remoção (4) da cavidade vaginal ou retal (40, 50), tendo a referida malha (1) uma extremidade proximal que corresponde à parte da malha (1) que entra em contato primeiro com a referida cavidade (40,50) e uma extremidade distal, que corresponde à parte da malha (1) que entra em último lugar na referida cavidade (40,5
