The present invention generally relates to medical devices, and more particularly to an improved intravascular device. In one embodiment, an intravascular device includes a catheter having proximal and distal portions, and a phased array of imaging elements, having edge elements each having angles of emission, located in the distal portion of the catheter, wherein the phased array is concaved having a radius of curvature such that when the phased array is steered in a maximal azimuthal direction, the angles of emission of the edge elements are substantially similar.
La présente invention concerne d'une manière générale des dispositifs médicaux et, plus particulièrement, un dispositif intravasculaire amélioré. Dans un mode de réalisation de l'invention, un dispositif intravasculaire comprend un cathéter possédant des parties proximale et distale et, une antenne réseau à commande de phase d'éléments d'imagerie, possédant des éléments d'arête, lesquels possèdent chacun des angles d'émission, situés dans la partie distale du cathéter, l'antenne à commande de phase est concave et possède un rayon de courbure tel que lorsque le réseau à commande de phase est dirigé dans un azimut maximal, des angles d'émission des éléments d'arête sont sensiblement similaires.
