A system and process for placing a percutaneous valve device in a body lumen at the location of implantation is provided. The placement system and method are simple and enhance the accuracy of the placement of the valve device. Anchors and placement wires or sutures are used to fix the implantation target and guide the device to the implantation site. The system and method are applicable to pre-assembled percutaneous valve devices as well as a modular prosthetic valve device, which modular device is also provided. The modular valve device comprises two or more device modules and is designed to be delivered unassembled and then assembled in the body lumen at or near the site where implantation occurs. The device modules may be assembled before or after the implantation target is fixed with the anchor, and then placed using the placement system in a manner similar to how a pre-assembled percutaneous valve device may be placed in accordance with the invention.

L'invention concerne un système et procédé de placement de dispositif de type valve percutanée dans un lumen corporel au niveau du site d'implantation. Le système et le procédé de placement sont simples et augmentent la précision du placement du dispositif à valve. On utilise des ancrages et fils ou sutures de placement pour fixer la cible d'implantation et guider le dispositif jusqu'au site d'implantation. Le système et le procédé sont applicables à des dispositifs à valve percutanée pré-assemblée de même qu'à un dispositif à valve prothétique modulaire, l'invention concernant également ce dispositif modulaire. Le dispositif à valve modulaire comprend deux ou plusieurs modules de dispositif et se pose sans être encore assemblé, donc avant assemblage dans le lumen corporel au niveau ou près du site d'implantation. Les modules de dispositif peuvent être assemblés avant ou après fixation de la cible d'implantation avec l'ancrage, avant mise en place à l'aide du système de placement de manière similaire au dispositif de type valve percutanée pré-assemblée conformément à l'invention.
