Abstract: An orientable catheter (10, 110, 210) comprising a first tubular body (16, 116, 216) having a distal portion with shape memory (26, 126, 226) which is curved at rest, and a second tubular body (38, 138, 238) having a distal stiffening portion (54, 154, 254) forming a stiffening element capable of sliding relative to the first tubular body (16, 116, 216) between a stiffening position in which the stiffening element (54, 154, 254) imposes a straightened configuration on the distal portion with shape memory (26, 126, 226), and a retracted position in which the stiffening element (54, 154, 254) does not interfere with the resting curved configuration of the distal end with shape memory (26, 126, 226).
