The medical device (10) has a prop (12) extending between a proximal end (12A) and a distal end, a nose (16) in the form of a perforating tip, secured to the distal end of the prop (12), a sheath (18), in which the prop (12) is housed, which can be moved by sliding between a first position in contact with the nose (16), and a second position spaced away from the nose (16), and at least one tube (22) extending in the sheath (18) between a proximal end (22A), accessible outside the sheath (18), and a distal end (22B) secured to the nose (16), the tube (22) having at least one perforation (24) near its distal end (22B). Each tube (22) can be radially deployed between a retracted configuration, in which each tube (22) can be covered by the sheath (18), and a radially protruding deployed configuration.
