    • An expandable stent comprises a cylindrical wall made up of lattice members connected to each other, at least one first arm and at least one second arm. The first arm comprises: a first non-linear member that is connected at each of its axial ends to a lattice member at respective first junctions; a second non-linear member connected at each axial end to a lattice member; and at least one bridge member extending between the first member and the second member. The second arm comprises: a first non-linear member that is connected at each of its axial ends to a lattice member; a second non-linear member connected at each axial end to a lattice member; and at least one bridge member extending between the first member and the second member. The second member of the first arm is generally U-shaped, extending from its axial ends towards: (i) a first axial end of the stent; and (ii) towards the bridge of the first arm. The second member of the second arm is generally U-shaped, extending from its axial ends towards: (i) a first axial end of the stent; and (ii) towards the bridge of the second arm. The first arm is disposed at a second axial end of the stent, and the second arm is: (i) axially spaced from the first arm towards the first axial end of the stent; and (ii) axially aligned with the first arm. Furthermore, the first member and the second member of each of the first and second arms are connected to lattice members at their axial ends only. Upon radial expansion of the stent from a radially crimped condition under the influence of an external force, tension in: (i) the bridge of the first arm; and (ii) the bridge member of the second arm, causes the second members of both the first and second arms to protrude radially outwards, respectively.

    • This invention relates to a protective buffer strap (10). More specifically, the invention relates to a protective buffer strap (10) capable of being strapped onto one or more articles (100, 200) to be closely restrained, thereby to prevent such articles (100, 200) from rubbing up against one another and causing damage, especially to surface finishes. The protective buffer strap (10) includes a strap (32) and an elongate body (12) from which the strap (32) extends, the elongate body (12) having a spine (26) and a plurality of projections (28) graduating lengths extending from the spine (26). The protective buffer strap (10) is configurable between an unwound condition and a wound condition. In the unwound condition, free ends (28A) of the projections (28) are spaced from one another along the spine (26). In the wound condition, the elongate body (12) and/or strap (32) is deformed into a closed loop form with the free ends (28A) of the protections (28) jointly defining at least a portion of a bore (36) for receiving a first article (100) therein, which bore (36) is eccentric relative to the closed loop form. Furthermore, in the wound condition, the strap (32) extends about the closed loop form and/or the closed loop form and a second article (200) receivable between the strap (32) and the spine (26) thereby to retain the protective buffer in the wound condition such that in use, the distance between the first article(100) received within the bore (36) and the second article (200) is variable by rotating the closed loop form about the first article (100).
