Abstract
(EN)
An ultrasound imaging device is disclosed having an elongated flexible tubular body (10), a rotatable drive shaft (12), and a nose member (26) located distally of the tubular body (10). The nose member (26) is mounted on the distal end of the drive shaft (12) to rotate therewith, and an acoustic imaging instrument (16) is incorporated in the nose member (26) for producing acoustic images of adjacent tissue as the drive shaft (12) turns. The nose member (26) is covered with a biocompatible, acoustically transparent, lubricous coating of hydrophilic material (24) sufficient to shield and space the nose member (26) from the adjacent tissue.

L'invention concerne un dispositif d'imagerie ultrasonore doté d'un corps tubulaire souple (10), d'une tige d'entraînement rotative (12) et d'un élément de tête (26) situé à l'extrémité distale de l'élément tubulaire (10). L'élément de tête (26) est monté sur l'extrémité distale de la tige d'entraînement (12) de sorte qu'il tourne avec ce dernier, un appareil d'imagerie acoustique (16), conçu pour produire des images acoustiques du tissu adjacent à mesure que la tige d'entraînement (12) tourne, étant intégré dans l'élément de tête (26). L'élément de tête (26) est recouvert d'un revêtement glissant, acoustiquement transparent et biocompatible constitué d'un matériau hydrophile de sorte que l'élément de tête (26) soit protégé et situé à une certaine distance du tissu adjacent.
