A cervical radiation therapy sleeve [1] is provided comprising a tube [2] suitable for containing radiation emitting therapy medium, a flange [3] at an operatively outer end thereof, and an operatively inner end [4], the sleeve having a length selected such that it extends operatively through the cervix [7] of a patient to terminate in the uterus [8]. The sleeve has, towards its inner end, at least two, and typically four, generally radially extending flexible barb formations [10, 14, 16, 18] arranged symmetrically about the axis of the sleeve and having remote free ends [11] spaced from the outer sleeve surface by a distance providing for co-operation thereof with the uterus wall to at least partially support the weight of the sleeve in the uterus and inhibit natural movement of the therapy sleeve out of its operative position. The barbs are configured to flex towards the sleeve to permit clinical introduction and removal of the sleeve. The sleeve is preferably made of plastic material that is flexible and preferably elastomeric. |
