A delivery apparatus (300) and a system (500). The delivery apparatus (300) comprises a sheath component (31), a tip (32), and a handle component (33). The sheath component (31) comprises an inner core tube (311), a push tube (313) sleeved on the inner core tube (311), and a sheath (314) sleeved on the push tube (313) and capable of moving axially relative to the push tube (313). The tip (32) is connected to the distal end of the inner core tube (311). The handle component (33) is connected to the proximal end of the sheath (314). A tube cavity channel (3131) for the inner core tube (311) to run through is provided within the push tube (313). A guide wire channel (3132) also is provided in the push tube (313). A limiting mechanism (321) is provided on the tip (32). The limiting mechanism (321) is used for being detachably connected to a guide wire (15 and 21) running through the guide wire channel (3132). The beneficial effect is: by providing in the push tube (313) the guide wire channels (3132) for the guide wire (15 and 21) to run through, and providing on the tip (32) the limiting mechanism (321) detachably connected to the guide wire (15 and 21), the limiting mechanism (321) ensures that the guide wire (15 and 21) is always connected to the limiting mechanism (321) during a delivery process, thus preventing the guide wire (15 and 21) from shifting and thereby affecting the overall positioning precision of the system.La présente invention concerne un appareil de distribution (300) et un système (500).
