Title (EN) MEDICAL IMPLANT LOCKING MECHANISM
(FR) MÉCANISME DE VERROUILLAGE D'IMPLANT MÉDICAL
Abstract:
(EN) A medical device system may include a replacement heart valve implant including an expandable anchor member reversibly actuatable between a delivery configuration and a deployed configuration, wherein the replacement heart valve implant includes at least one locking mechanism configured to lock the expandable anchor member in the deployed configuration, and at least one actuator element configured to releasably engage the at least one locking mechanism and actuate the expandable anchor member between the delivery configuration and the deployed configuration. The at least one actuator element may include external threads on a distal portion of each actuator element and a ramp disposed proximal of the external threads.
(FR) L'invention concerne un système de dispositif médical qui peut comprendre un implant de valvule cardiaque de remplacement comprenant un élément d'ancrage expansible pouvant être actionné de façon réversible entre une configuration de pose et une configuration déployée, l'implant de valvule cardiaque de remplacement comprenant au moins un mécanisme de verrouillage, configuré pour verrouiller l'élément d'ancrage expansible dans la configuration déployée, et au moins un élément d'actionneur, configuré pour mettre en prise de manière libérable le ou les mécanismes de verrouillage et pour actionner l'élément d'ancrage expansible entre la configuration de pose et la configuration déployée. Le ou les éléments d'actionneur peuvent comprendre des filetages externes sur une partie distale de chaque élément d'actionneur et une rampe disposée à proximité des filetages externes.
