Abstract
An ISC (intermittent self catheterisation) catheter 10 is formed of a blend of synthetic polymer, e.g. PVC, and a natural biodegradable organic material such as collagen, chitosan or corn starch. The catheter 10 is supplied in a package 1 sealed in an envelope 2 formed of a material which is impermeable to moisture. The catheters are therefore suitable to be disposed of in regular collection schemes, but when sealed within the moisture-excluding envelope 2 the catheters have a normal shelf life.
