A flexible body comprises a polymer film having a first surface and an opposing second surface. The polymer film has a plurality of apertures extending from the first surface to the second surface and a plurality of raised lips protruding from the first surface such that each of the plurality of apertures is surrounded by one of the plurality of raised lips. A method of producing a polymer film comprises placing a polymer solution into a one sided mold having a plurality of protrusions extending from a bottom of the mold wherein the polymer solution is characterized by a viscosity that inhibits the unaided flow of the polymer throughout the mold urging the polymer solution around each of the plurality of protrusions and solidifying the polymer solution.一種可撓物體,其包含具有第一表面及相對之第二表面的聚合物膜。該聚合物膜具有多個由該第一表面延伸至該第二表面的孔及多個由該第一表面所凸出之高起的開口(lip),以致該多孔各自受該多個高起的開口之一者所環繞。一種製造聚合物膜之方法包含將聚合物溶液放入具有多個由模底部延伸之凸出體的單面模(one sided mold)中,其中該聚合物溶液特徵在於抑制該聚合物無外力流遍該模之黏度;促動該聚合物溶液環繞該多個凸出體之每一者;且固化該聚合物溶液。10‧‧‧膜12‧‧‧醫療裝置
