Abstract
The instrument includes a dual-wall deformable tube, with an inner sleeve, a coaxial outer sleeve, and an imaging module connected to the inner and outer sleeves. An array of transducers is carried by an outer face of the imaging module. The inner sleeve and the outer sleeve are mobile in relative axial translation between: a folded position in which the inner and outer sleeves both have a cylindrical shape, and in which the imaging module substantially extends in the continuation of the inner sleeve; and an expanded position, in which the inner sleeve has a cylindrical shape and the outer sleeve has a flared shape widening on the distal side and in which the imaging module substantially extends with the face that carries the transducers of the array turned in axial direction towards the front of the deformable tube.
