Embodiment Construction

[0035] The belt part 1 of the medical device can be placed annularly around the body tissue 2 (here the urinary catheter) surrounding the body passage. The belt part 1 has a hollow space 3 which extends in the direction of the longitudinal extension of the belt part 1 , in the exemplary embodiment substantially over the entire length of the belt part 1 . The belt part 1 is thus designed in the form of a tube with ends closed on both sides.

[0036] At both ends of the belt part 1 a first closure part 6 and a second closure part 7 are arranged. The first closure part 6 has an insertion opening 6a into which the tongue 7a of the second closure part 7 can be inserted and snapped in, cf. Image 6 .

[0037] The closing parts 6, 7 thus form a closing part with which the belt part 1 can be closed into a loop, in particular a circular ring, cf. Figure 7 . In the closed state, the belt part 1 encloses a through-opening 4 for the body tissue 2 surrounding the body passage.

Abstract

The invention relates to a medical arrangement for shutting off a body channel, comprising: a band section (1) that can be placed around the body tissue (2) surrounding said body channel and can be closed to form a ring enclosing a passage opening (4) for the body tissue (2), and that comprises a cavity (3) which makes up one part of a working fluid receiving chamber of the arrangement, for receiving working fluid; and a pump unit (10) for conveying said working fluid. The passage opening (4) can be made smaller by introducing the working fluid into the cavity (3). The arrangement also comprises a storage container (22) that has a flexible wall (22a) which delimits a storage chamber (23), wherein to apply an additional force to the body tissue (2) guided through the passage opening (4), the volume of the storage chamber (23) can be made smaller by increasing an ambient pressure acting on the storage container (22), wherein the wall (22a) of the storage container (22) is designed to beat least substantially non-extensible.

Description

technical field [0001] The invention relates to a medical device for blocking a body passage comprising a band which can be placed around body tissue surrounding the body passage and which can be closed to enclose a through opening for the body tissue and the belt member has a hollow cavity that is part of a working fluid-accommodating space of the device for containing a working fluid, and the medical device includes a pump unit for delivering a working fluid, wherein , the through-opening can be made smaller by bringing the working fluid into the hollow cavity, and the medical device comprises a storage container with a flexible wall delimiting the storage cavity, wherein, in order to apply an additional force to the through-through On open body tissue, the volume of the storage chamber can be reduced by increasing the ambient pressure acting on the storage container. Background technique [0002] Medical devices for blocking bodily passages are furthermore used as artifi...
