<p>A resiliently flexible body having a non-spherical shape and having a magnetizable portion for use in sealing an anatomical cavity such as a urinary bladder. The body is compressed and then inserted into the cavity. In the cavity the body is experimented and positioned at the cavity outlet. The body is rotated in the outlet using a hand-held magnet between a sealing orientation in which the outlet is sealed, and a non-sealing orientation in which fluid, such as urine, can flow out of the cavity.</p> |
