Abstract

A medical system may include a shaft member and a structure physically coupled to the shaft member. A portion of the shaft member may be sized to be delivered through a bodily opening leading to a bodily cavity. The structure may include at least two flexible couplings, each flexible coupling extending transversely from an intermediate portion of a respective one of at least two elongate members of the structure. The flexible coupling extending transversely from the intermediate portion of a first one of the at least two elongate members forms at least a part of a first closed loop arranged to receive a portion of the flexible coupling of a second one of the at least two elongate members therethrough to limit a spacing between the intermediate portions of the first and the second ones of the at least two elongate members.
