Abstract

A medical apparatus (100) is provided, comprising a closure device (102), which comprises a locking member (130) and a tubular member (121) having two sets of struts (122, 123) being provided with a hinge section, and an insertion assembly (101), which comprises a holder (106) and an actuator (107), the holder being releasably engaged in the locking member and the actuator being releasably engaged with the tubular member. The insertion assembly further comprises a spring (105) which effectuates a relative movement between the holder and the actuator, which causes the closure device to move from a first elongated introduction configuration via a second positioning configuration to the third closed configuration, during which the tubular member is compressed such that the hinge sections have moved radially away from a longitudinal central axis of the closure device. The compression of the device can be reversed if needed, yet the device can not be compressed further without providing force in excess of the spring force, whereby the final irreversibly locked state is achieved.
