Cryoprobe and method of manufacturing the same

Cryoprobe (12) apparatus comprising:

• a tube device (14) that has a first channel (16) having arranged, in its distal end, a nozzle (24) with a nozzle shaft (24a) so that the nozzle (24) projects beyond an end of the first channel (16) and the nozzle shaft (24a) is inserted into a length of the first channel (16), and the tube device (14) also has a second channel (17) arranged at least parallel to and at a distance from the first channel (16), said second channel having a cross-section that is greater than a cross-section of one or both of the nozzle (24) and the first channel (16),
• a sleeve (20) that is arranged on a distal tube end (19) of the tube device (14) and that has an inside clearance which—at least in a completely assembled state—is smaller than an outside diameter of the tube device (14), and
• an end cap (21) that is arranged on a distal end of the sleeve (20) such that the end cap (21) closes said sleeve,
• wherein the sleeve (20) either is deformed radially inward in at least one compression zone (31, 32) where the distal tube end (19) is compressed or has an inside diameter smaller than the outside diameter of the tube device (14) such that the tube device (14) where the tube device (14) overlaps with the sleeve (20) is compressed, which includes the at least one compression zone (31, 32), and
• wherein the at least one compression zone (31, 32) at least partially overlaps the length of the first channel (16) in which the nozzle shaft (24a) is inserted such that compression of the distal tube end (19) compresses at least a portion of the first channel (16) against the nozzle shaft (24a).
