Title (EN) MEDICAL DEVICE LEAD INCLUDING A UNIFILAR COIL WITH IMPROVED TORQUE TRANSMISSION CAPACITY AND REDUCED MRI HEATING
(FR) DÉRIVATION DE DISPOSITIF MÉDICAL COMPRENANT UNE BOBINE UNIFILAIRE DOTÉE D'UNE CAPACITÉ DE TRANSMISSION DE COUPLE AMÉLIORÉE ET UN CHAUFFAGE PAR IRM RÉDUIT
Abstract: front page image
(EN)A conductor assembly for a medical device lead includes a helically coiled conductor including a plurality of turns having a coil pitch and an outer diameter and consisting of one filar having a filar diameter. The coil pitch and outer diameter are selected based on the filar diameter to minimize heating of the helically coiled conductor in the presence of an MRI field. A polymer sheath is formed about the helically coiled conductor such that the coil pitch of the unifilar helically coiled conductor is maintained. The polymer sheath is configured to increase a torque transmitting capacity of the helically coiled conductor.
(FR)La présente invention concerne un ensemble conducteur destiné à une dérivation de dispositif médical et comprenant un conducteur enroulé en hélice doté d'une pluralité de spires ayant un pas de bobinage et un diamètre externe et constitué d'un fil ayant un diamètre de fil. Le pas de bobinage et le diamètre externe sont choisis sur la base du diamètre du fil afin de minimiser le chauffage du conducteur enroulé en hélice en présence d'un champ IRM. Une gaine en polymère est formée autour du conducteur enroulé en hélice de manière à préserver le pas de bobinage du conducteur unifilaire enroulé en hélice. La gaine en polymère est configurée pour augmenter une capacité de transmission de couple du conducteur enroulé en hélice.
