Catheter with flexible and elongate body

A medical or surgical probe, intended to be introduced into a body passage and provided with at least two individual longitudinal channels, each extending between the proximal end and the distal end of said probe, this probe including:

• a flexible and elongate body (2, 30, 50) intended to be introduced via its distal end (3) into said body passage and provided with at least two internal longitudinal conduits (9, 10;
• 35, 36, 37;
• 60, 61, 62, 63);
• and
• at least two flexible and elongate proximal branches (11, 12) which are each provided with an internal longitudinal conduit (9, 10) and are arranged at the proximal end of said elongate body, each of the conduits of said branches continuing a conduit of said elongate body in order to form one of said individual longitudinal channels of said probe,
• wherein:
• said flexible and elongate body (2, 30, 50) includes, in addition to said internal longitudinal conduits, a central longitudinal channel (4, 31, 55) delimiting, within said body, longitudinal portions (5, 6;
• 32, 33, 34;
• 51, 52, 53, 54) connected to one another by surface material lines, which are easily tearable open;
• each of said longitudinal portions of the body includes one of said internal longitudinal conduits (9, 10;
• 35, 36, 37;
• 60, 61, 62, 63);
• each of said proximal branches (11, 12) is formed by one such longitudinal portion of said body, separated from said other longitudinal portions, over a limited length, along said tearable surface material lines;
• and
• said central longitudinal channel (4, 31, 55) has a cross section which is capable of receiving a tubular element (18) which can be attached to said elongate body, at the junction (13) of said proximal branches (11, 12) of said probe.
