Abstract

A photosensitizer together with complementary light energy are used to prevent the development of infection associated with an indwelling medical catheter or device. Light of a selected wavelength or wavelength band is coupled to the catheter or device and transmitted by a wall or walls thereof to one or both of the external and internal surfaces thereof. The catheter or device also incorporates at least one photosensitizer which releases a toxic substance when activated by the light energy which destroys bacteria on or around the catheter or device. A method of preventing infection using photosensitizers and complementary light energy is also disclosed.
