Abstract: A method of collecting a biological sample inside a body cavity (18) using filaments (132). The body cavity (18) is accessed with the filaments (132) contained in a sheath (126) with ends thereof spaced apart from each other. To collect the sample, the filaments (132) are deployed outside the sheath (126) in the body cavity (18) and the ends of the filaments (126) are longitudinally brought closer to each other to bulge the portion extending therebetween to a radius larger than the radius of the sheath 126). Also, a device (100, 300) for performing the method.

Abstract: A device (10) for collecting a sample from a uterus (14). The device includes a core (24) defining a core outer surface (28) and a distal brush section (30) provided with brush bristles (32) extending from the core outer surface (28). A sheath (26) receives at least part of the core (24) thereinto and defines axially opposed sheath proximal and distal ends (34 and 36). The core (24) and sheath (26) are movable relative to each other between a device retracted configuration and a device expanded configuration, wherein, in the device retracted configuration, the brush bristles (32) are compressively contained within the sheath (26) in a brush bristle compressed configuration, and, in the device expanded configuration, the brush bristles (32) are outside the sheath (26), distally to the sheath distal end (36), in a brush bristle expanded configuration wherein the brush bristles (32) span a larger volume than in brush bristle compressed configuration.
