Title (EN) DEVICES AND METHODS FOR VASCULAR NAVIGATION, ASSESSMENT AND/OR DIAGNOSIS
(FR) DISPOSITIFS ET MÉTHODES DE NAVIGATION, D'ÉVALUATION ET/OU DE DIAGNOSTIC VASCULAIRES
Abstract:
(EN) Devices and methods for vascular navigation, assessment and/or diagnosis are disclosed where a location detection system generally includes an elongate body defining a lumen at least partially along a length of the elongate body. One or more sensors are positioned near or at a distal tip of the elongate body and one or more openings are defined along the elongate body in proximity to the one or more sensors. The one or more openings are configured to control a boundary distance between the one or more sensors and a fluid with a parameter of a known initial value when emitted from the one or more openings. A controller is in communication with the one or more sensors and is configured to track a change in the parameter relating to concentration over the one or more sensors and determine a position of the one or more sensors within a body.
(FR) L'invention concerne des dispositifs et des méthodes de navigation, d'évaluation et/ou de diagnostic vasculaires dans lesquels de manière générale un système de détection d'emplacement comprend un corps allongé définissant une lumière sur au moins une partie de la longueur du corps allongé. Un ou plusieurs capteurs sont positionnés à proximité ou à l'extrémité distale du corps allongé et une ou plusieurs ouvertures sont définies le long du corps allongé à proximité du ou des capteurs. La ou les ouvertures sont conçues pour réguler une distance limite entre le ou les capteurs et un fluide ayant un paramètre d'une valeur initiale connue quand il est émis par la ou les ouvertures. Un dispositif de commande est en communication avec le ou les capteurs et est conçu pour suivre un changement du paramètre relatif à la concentration sur le ou les capteurs et pour déterminer une position du ou des capteurs à l'intérieur du corps.
