Embodiment Construction

[0039] The belt part 1 of the medical device can be placed annularly around body tissue 2 (here a urinary catheter) surrounding a 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.

[0040] At these two 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 6 a into which the tongue 7 a of the second closure part 7 can be inserted and latched.

[0041] The closing parts 6, 7 thus form a closing part (Verschluss), with which the belt part 1 can be closed into a ring, in particular a circular ring, cf. Figure 5 . In the closed state, the belt part 1 encloses a through-opening 4 for the body tissue 2 surrounding the body passage.

Abstract

A medical device for blocking a body passage, the medical device comprising a strap part (1) which can be placed around body tissue (2) surrounding the body passage and which can be closed to enclose the body tissue (2) and the belt part has a hollow cavity (3) which is part of the containing space of the device for containing the working fluid, and the medical device comprises a pump unit (10), the The pump unit is used to transport the working fluid. The through opening (4) can be made smaller by bringing the working fluid into the hollow cavity (3). The device has an expansion body (20) with an expansion chamber (21), wherein the expansion body (20) is arranged in a receiving space for the working fluid or on the belt part (1) at the At the side facing the through opening (4), and the expansion chamber (21) can be enlarged by bringing an auxiliary fluid separated from the working fluid into the expansion chamber (21).

Description

technical field [0001] The present invention relates to a medical device for blocking a body passage, the medical device comprising a band part (Bandteil) and a pump unit, the band part can be placed around the body tissue surrounding the body passage and can be closed to enclose the body tissue for and the belt member has a hollow cavity that is part of a housing space of the device for containing a working fluid, and the medical device includes a pump unit for delivering the working fluid, wherein , the through opening can be made smaller by bringing the working fluid into the hollow cavity. Background technique [0002] Medical devices for blocking bodily passages are also used as artificial (sphincter) muscles for supporting or for replacing weak natural muscles in the human or animal body. Examples of areas of use for such devices are anal bands for closing the (if possible artificial) anus and artificial sphincters for closing the urethra (=urethra) for the treatment ...
