The assembly includes a carrier element 10 provided with an elongate cannula or catheter 12 upon which a plurality of sleeves 20 are disposed. The sleeves 20 are located within a zone (18, fig 1) at which a medical device 40 is carried. The sleeves 20 include restraining mechanisms, typically channels (30, fig 2), for receiving respective trigger wires 42, 44. The medical device 40 is radially constrained by the trigger wires in combination with the sleeves. The sleeves 20 are initially provided as separate elements which are fitted onto the elongate carrier 12 in a number and at locations suitable for the medical device 40 to be located on the carrier element. The arrangement provides a simple and effective restraining structure which can be adapted for different medical devices 40 and an arrangement in which the medical device (40) is radially constrained from within.
