Title
(EN) FIXATION COMPONENT FOR MULTI-ELECTRODE IMPLANTABLE MEDICAL DEVICE
(FR) COMPOSANT DE FIXATION POUR DISPOSITIF MÉDICAL IMPLANTABLE À ÉLECTRODES MULTIPLES
Abstract
(EN)
An example fixation component for an implantable medical device (IMD) includes a base and tines extending from the base and being spaced apart from one another. The tines include a penetrator tine and a protector tine. The penetrator tine includes a curved section defining a deformable preset curvature that extends laterally from a proximal section that is fixed to the base, traversing a longitudinal axis of the fixation component, to a distal section that terminates in an incisive distal end that is configured to penetrate a tissue to form a puncture. The protector tine includes a curved section defining a deformable preset curvature that extends from a proximal section that is fixed to the base, outward from the longitudinal axis, to a distal section that terminates in a non-incisive distal end that is configured to pass through the puncture.

Un exemple de composant de fixation pour un dispositif médical implantable de l'invention comprend une base et des dents s'étendant depuis la base et étant espacées l'une de l'autre. Les dents comprennent une dent de pénétration et une dent de protection. La dent de pénétration comprend une section incurvée définissant une courbure prédéfinie déformable qui s'étend latéralement depuis une section proximale fixée à la base, traversant un axe longitudinal du composant de fixation, jusqu'à une section distale qui se termine par une extrémité distale tranchante configurée pour pénétrer dans un tissu afin de pratiquer une perforation. La dent de protection comprend une section incurvée définissant une courbure prédéfinie déformable qui s'étend depuis une section proximale fixée à la base, vers l'extérieur de l'axe longitudinal, jusqu'à une section distale qui se termine par une extrémité distale non tranchante configurée pour traverser la perforation.
