摘要： Methods and apparatus provide therapeutic electromagnetic radiation (EMR) for inactivating infectious agents in, on or around a catheter residing in a patient's body cavity and/or for enhancing healthy cell growth. Transmitting non-ultraviolet therapeutic EMR substantially axially along an optical element in a lumen of the catheter body and/or the catheter body. Through delivery of the therapeutic EMR to particular infected areas and/or areas requiring tissue healing. The inactivation of the major sources of infection in, on, and around catheters and/or enhance healthy cell growth around catheters is accomplished by utilizing controlled relative intensity and/or treatment region specific dosing of the therapeutic EMR emitted radially from the optical element. Specific embodiments of urinary catheters and peritoneal dialysis catheters are also disclosed.

摘要： A medical device assembly is provided for removable insertion into a catheter with a lumen. The medical device assembly comprises an electromagnetic radiation (EMR) source for providing non-ultraviolet, therapeutic EMR having an intensity sufficient to inactivate one or more infectious agents and/or to stimulate healthy cell growth causing a healing effect, and a removable EMR conduction system at least partially insertable into and removable from the lumen of the catheter. The EMR conduction system has at least one optical element providing axial propagation of the therapeutic EMR through an insertable elongate body. The elongate body may have an exterior surface between a coupling end and a distal end tip that has at least one modified portion permitting the radial emission of therapeutic EMR from the elongate body proximate the modified portion. Such modified portion may be gradient along the exterior surface.
