    摘要: The invention provides compositions for the inhibition of bacterial adhesion. The composition can include nanocrystalline cellulose (NCC) and a water-soluble polymer, which form an NCC hydrogel in water. The NCC hydrogel can be used to treat or coat devices such as a catheter, whereby the NCC hydrogel inhibits bacterial adhesion to the catheter surface to thereby inhibit biofilm formation and growth of bacteria on the catheter surface. The compositions and devices can thus be useful for inhibiting or preventing conditions such as urninary tract infections.

    摘要: A medical balloon (24,30)for a balloon catheter (10)is described. The balloon(30)has at least a first layer (40)made from a first material and a second layer (42)made from a second material, said first (40)and second (42)layers being in overlying relationship with one another and being integral with one another; wherein the first layer (40)has a softening or melting temperature which is higher than a softening or melting temperature of the second layer (42). A method of forming the medical balloon (30)is also described, including locating a raw tubing(131)in a mould(112); preheating and inflating the raw tubing (131)so as to cause it to stretch; heating the raw tubing (131)to soften or melt the second layer(42); setting the inflated raw tubing (131)to form the medical balloon(30); and cooling the set balloon(30).
