Title (EN) COATED PROSTHETIC CARDIAC DEVICE
(FR) PROTHESE CARDIAQUE POURVUE D'UN REVETEMENT
Abstract: front page image
(EN)The present invention includes a metallic coating on portions of the prosthesis (10) to enhance the overall acceptability of the implantable device (10) or fabric/sutures used to implant the prosthesis. The preferred metal is silver, which is applied to surfaces which are exposed to the heart tissue. The silver-treated portions of these devices inhibit or greatly reduce colonization of endocarditis-causing bacteria without impacting the overall biocompatibility of the device. A passive elastic assist device in the form of a girdle to be fitted onto the ventricles is described inorder to increase myocardial contractility.
(FR)La présente invention concerne un revêtement métallique recouvrant des portions de la prothèse (10), afin d'accroître l'acceptation globale de la prothèse implantée (10), ou recouvrant le tissu/les fils de sutures utilisés pour implanter celle-ci. Le métal préféré est de l'argent, que l'on applique sur les surfaces qui sont exposées au tissu cardiaque. Les portions de ces dispositifs, traitées à l'argent, inhibent ou diminuent grandement la colonisation des bactéries provoquant l'endocardite, sans nuire à la biocompatibilité globale de la prothèse. L'invention concerne également un dispositif d'aide élastique passive, sous la forme d'une coque que l'on ajuste sur les ventricules, de manière à augmenter la contractilité myocardique.
