Claim:
1. A sealing assembly configured to be deployed downhole comprising a sleeve adapted to be mounted on a tubular body, both of which are disposable within a bore, the sleeve including a swellable sealing arrangement comprising a swellable material and inner and outer seals mounted, in a first configuration prior to swelling, on inner and outer surfaces of the sleeve respectively, wherein the inner seal extends along a partial axial length of the sleeve, and whereby the swellable sealing arrangement is configured such that, in a second configuration, swelling of the swellable material causes the inner seal to extend radially inwardly from the inner surface of the sleeve so as to make sealing contact with the mounted tubular body and establish a seal between the sleeve and the mounted tubular body, and further causes the outer seal to extend radially outwardly from the outer surface of the sleeve so as to make sealing contact with a wall of the bore and establish a seal between the sleeve and the wall of the bore.
