Abstract
A retention device which can be removably retained in a body cavity has branch members which are movably connected to each other such that two relative configurations may be obtained. In one configuration the branch members are nested inside one another for inserting the retention device in a cavity. Once in a cavity an operating member is used to displace the branch members to form the second configuration, in which parts of the branch members are expanded to bear against the walls of the cavity and retain the device.
