Title
(EN) METHODS AND APPARATUS TO DELIVER THERAPEUTIC, NON-ULTRAVIOLET ELECTROMAGNETIC RADIATION IN A DIALYSIS SYSTEM
(FR) PROCÉDÉS ET APPAREIL PERMETTANT DE DÉLIVRER UN RAYONNEMENT ÉLECTROMAGNÉTIQUE NON-ULTRAVIOLET THÉRAPEUTIQUE À UN SYSTÈME DE DIALYSE
Abstract
(EN) 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, peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.
(FR) La présente invention concerne des procédés et un appareil fournissant un rayonnement électromagnétique thérapeutique (REM) pour l’inactivation d’agents infectieux dans, sur ou autour d’un cathéter résidant dans une cavité corporelle d’un patient et/ou pour améliorer la croissance des cellules saines. Le procédé consiste à transmettre un REM thérapeutique non ultraviolet de manière sensiblement axiale le long d'un élément optique dans une lumière du corps de cathéter et/ou dans le corps de cathéter par la délivrance du REM thérapeutique à des zones infectées particulières et/ou nécessitant une cicatrisation tissulaire. L’inactivation des sources principales d’infection dans, sur et autour des cathéters et/ou l’amélioration de la croissance des cellules saines autour des cathéters est réalisée en utilisant l’intensité relative contrôlée et/ou le dosage spécifique à la région de traitement de REM thérapeutique émis radialement depuis l’élément optique. Des modes de réalisation spécifiques de cathéters urinaires, de cathéters de dialyse péritonéale, d'accès à la dialyse et d'accès à l'hémodialyse sont également divulgués.
