Abstract

A blood circulation assistance device (1) comprises one or more cuff elements (3) which define a chamber for receiving a blood conduit (6). The chamber is open at both ends of the one or more cuff elements (3) for the blood conduit (6) to extend therethrough. There is an aperture (22) in the side of the one or more cuff elements (3) between each end of the chamber for locating the one or more cuff elements (3) about the blood conduit (6). The one or more cuff elements (3) bear two inwardly expanding inflatable elements (4, 5) for compressing the blood conduit (6). The inflatable elements (4, 5) are disposed diametrically opposite each other across the chamber.
