(FR) ENDOPROTHÈSE OU CATHÉTER URÉTÉRAL REVÊTU ET/OU IMPRÉGNÉ ET PROCÉDÉ
Abstract
(EN)
A coated and/or impregnated urinary catheter or urinary stent device, including: (a) a proximal portion; and (b) a distal portion, the distal portion comprising a retention portion that includes at least one protected drainage hole(s), port(s) or perforation(s) and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the at least one protected drainage hole(s), port(s) or perforation(s) upon application of negative pressure through the catheter; and at least one coating(s) upon and/or at least one impregnation(s) within at least a portion of the protective surface area, the at least one coating(s) and/or at least one impregnation(s) including at least one of lubricant(s), antimicrobial material(s), pH buffer(s) or anti-inflammatory material(s)
(FR)
L'invention concerne un cathéter urinaire ou un dispositif d'endoprothèse urinaire revêtu et/ou imprégné, comprenant : (a) une partie proximale ; et (b) une partie distale, la partie distale comprenant une partie de retenue qui comprend au moins un trou, un orifice ou une perforation d'évacuation protégé et étant conçue pour constituer une périphérie externe ou une zone superficielle de protection qui empêche un tissu muqueux de boucher ledit ou lesdits trous, orifices ou perforations d'évacuation protégés lors de l'application d'une pression négative dans le cathéter ; et au moins un revêtement sur au moins une partie de la zone superficielle de protection et/ou au moins une imprégnation à l'intérieur de celle-ci, le ou les revêtements et/ou la ou les imprégnations comprenant au moins un ou des lubrifiants, une ou des substances antimicrobiennes, un ou des tampons de pH ou une ou des substances anti-inflammatoires.
