Title
(EN) MAMMALIAN BODY IMPLANTABLE FLUID FLOW INFLUENCING DEVICE
(FR) DISPOSITIF INFLUENÇANT UN ÉCOULEMENT DE FLUIDE POUVANT ÊTRE IMPLANTÉ DANS UN CORPS DE MAMMIFÈRE
Abstract
(EN) Mammalian body implantable fluid flow influencing device, comprising a modular impeller having: An impeller hub module dimensioned and shaped to be deliverable to a delivery site within a conduit of a conduit system of the mammalian body via a catheter. An impeller vane module having at least a portion of an impeller vane; having, with respect to the impeller hub module, an assembled configuration in which the impeller vane module mates with the impeller hub module, and an unassembled configuration, in which the impeller vane module is unmated with the impeller hub module and being dimensioned and shaped to be deliverable to the delivery site via the catheter when in the unassembled configuration. The modular impeller being formed when the impeller vane module is retained in its assembled configuration, and dimensioned and shaped to be operable within at least one conduit of the conduit system. Method of implantation disclosed.
(FR) Dispositif influençant un écoulement de fluide pouvant être implanté dans un corps de mammifère, comprenant une pale modulaire ayant : un module moyeu de pale dimensionné et mis en forme pour pouvoir être administré au niveau d’un site d’administration à l’intérieur d’une conduite d’un système de conduite du corps de mammifère par l’intermédiaire d’un cathéter. Un module vanne de pale ayant au moins une portion d’une vanne de pale ; ayant, par rapport au module moyeu de pale, une configuration assemblée dans laquelle le module vanne de pale s’accouple au module moyeu de pale, et une configuration non assemblée, dans laquelle le module vanne de pale n’est pas accouplé au module moyeu de pale et étant dimensionné et mis en forme pour pouvoir être administré au site d’administration par l’intermédiaire des cathéters lorsqu’il se trouve dans la configuration non assemblée. La pale modulaire est formée lorsque le module vanne de pale est retenu dans sa configuration assemblée, et dimensionnée et mise en forme pour pouvoir fonctionner à l’intérieur d’au moins une conduite du système de conduite. Est divulgué un procédé d’implantation.
