Apparatus for inflating a balloon (10) and keeping the balloon inflated whilst a substance (13) is introduced into the balloon, comprises a container (1) having a lid (2). The lid has an opening (4) arranged such that a balloon can be positioned in the container with its neck open, aligned* with the opening and in sealing engagement with the lid. A non-return valve (3) permits gas to be displaced from the space in the container outside the balloon whilst the balloon is inflated. The non-return valve (3) is provided in a conduit (7) extending from the lid (2) to adjacent the base of the container. Once the balloon (10) has been inflated the substance (13) can be introduced into the balloon by a funnel (12). A release valve (6) is provided to permit controlled introduction of gas into the space in the container outside the balloon, so as to permit controlled contraction of the balloon around the substance.
