An ultrasound medical system (94) includes a tube (96) and resiliently flexible fingers (98). The tube (96) has a distal end insertable into a patient and has a lumen (102) with a distal opening (104). The fingers (98) are extendable out of the distal opening (104) of the lumen (102) creating a deployed state and are at-least-partially retractable into the distal opening of the lumen creating a stowed state. Each finger includes an ultrasound transducer (106), wherein the distance between the transducers of adjacent fingers is greater in the deployed state than in the stowed state. In one example, at least one of the transducers is an ultrasound imaging transducer, an ultrasound medical-treatment transducer, or an ultrasound imaging and medical treatment transducer.

L'invention concerne un système médical ultrasonore comprenant un tube et des doigts souples de manière élastique. Le tube présente une extrémité distale pouvant être introduite dans un patient et une lumière dotée d'une ouverture distale. Les doigts peuvent être étendus en dehors de l'ouverture distale de la lumière, créant un état déployé et sont, au moins partiellement, rétractables dans l'ouverture distale de la lumière, créant ainsi un état rangé. Chaque doigt comprend un transducteur ultrasonore, la distance entre les transducteurs de doigts adjacents est supérieure dans l'état déployé que dans l'état rangé. Dans un exemple, au moins un des transducteurs est un transducteur d'imagerie ultrasonore, un transducteur de traitement médical ultrasonore ou un transducteur d'imagerie et de traitement médical ultrasonore.
