Title (EN) LEADLESS CARDIAC PACEMAKER WITH SECONDARY FIXATION CAPABILITY
(FR) STIMULATEUR CARDIAQUE SANS FIL AVEC CAPACITÉ DE FIXATION SECONDAIRE
Abstract:
(EN) The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS' s may either actively engage an attachment site, or more passively engage structures within a heart chamber. Active secondary fixation elements include a tether extending from the LBS to an anchor at another site. Such sites may be either intracardial or extracardial, as on a vein through which the LBS was conveyed to the heart, the internal or external surface thereof. Passive secondary fixation elements entangle within intraventricular structure such as trabeculae carneae, thereby contributing to fixation of the LBS at the implant site.
(FR) La présente invention concerne des stimulateurs cardiaques sans fil (LBS), et des éléments et des procédés par lesquels ils se fixent au cœur. L'invention concerne en particulier une fixation secondaire de stimulateurs sans fil qui comprennent également une fixation primaire. Des éléments de fixation secondaire pour des LBS peuvent soit coopérer activement avec un site d'attache, soit coopérer plus passivement avec des structures au sein d'une chambre cardiaque. Des éléments de fixation secondaires actifs comprennent un filin s'étendant du LBS à une ancre au niveau d'un autre site. De tels sites peuvent être soit intracardiaques, soit extracardiaques, comme sur une veine à travers laquelle le LBS a été acheminé vers le cœur, sa surface interne ou externe. Des éléments de fixation secondaires passifs s'entremêlent dans la structure ventriculaire telle que des colonnes charnues, contribuant ainsi à fixer le LBS au niveau du site d'implant.
