A peritoneal dialysis catheter has annular cuffs at one or more locations along its length. The cuffs are of a woven material to promote tissue ingrowth and thereby anchor the catheter to the body. The catheter has internal channels extending from ports located outside the body to deliver disinfecting fluid to the space between the cuffs and the catheter exterior, preventing infections from reaching the cuffs and reducing the frequency of new implants.
L'invention porte sur un cathéter pour dialyse péritonéale comportant des manchons annulaires à un ou plusieurs endroits sur toute sa longueur. Les manchons sont faits d'étoffe tissée pour favoriser l'interposition de tissus et ainsi fixer solidement le cathéter au corps. Le cathéter comporte des canaux internes, se prolongeant des orifices placés à l'extérieur du corps, servant à faire couler un liquide désinfectant jusque dans l'espace entre les manchons et l'extérieur du cathéter. Il est ainsi possible d'empêcher toute infection d'atteindre les manchons et, par conséquent, de réduire la fréquence d'insertion de nouveaux implants.
