Embodiment Construction

[0025] The blocking device according to the invention is in figure 1 The middle is generally indicated by the reference number 1 . Said blocking means comprise a central line 2 branching into arcuate portions 3 at both ends. That is to say the central portion is located between the arcuate portions. It has a cladding made of silicon material 4 . Due to the curved shape of the arcuate portion 3 an optimal positioning in the fallopian tube can be determined. A ring, preferably likewise made of a metal wire that does not react with the environment of the body, is indicated by the reference number 5 . By means of this ring, the blocking device 1 can be removed after installation.

[0026] exist figure 2 in, with figure 1 A similar embodiment is indicated generally by reference numeral 11 . In this case there is also a central silver line 12 extending towards the arcuate portion 13 . In this embodiment, only the arcuate portion is provided with a cladding such as silicon m...

Abstract

Blocking device for fallopian tubes and interventional device therefor. The blocking device comprises a central part with elongated retaining members on either side thereof, which are movable between an intervening position and a retaining position. In the intervention position, the retaining member is in line with the central part. The interventional device consists of a structure comprising a handle, a central bush and a sliding bushing, so that, on the one hand, it is possible to move the blocking device over a predetermined distance within the interventional cannula when it comes into contact with the constricted part of the fallopian tube, and on the other hand After the blocking device has been placed in the correct position, the blocking device is allowed to open without further movement.

Description

technical field [0001] The invention relates to an occlusion device comprising a central part and two elongated retaining parts connected on either side of the central part and movable between an intervention position and a use position, said retaining parts being in contact with The center part is straight. Background technique [0002] US 5,669,933 discloses a blocking device of this type. Wherein the purpose of the occlusion device is to insert the occlusion device into the vascular channel at one time. Holding members are arranged at both ends of the central part. The retaining member at one end may be folded in line with the central portion. The retaining member at the other end may be folded to overlap the central portion. The latter-mentioned retaining part is bent away from the central part. [0003] US 4,595,000 A describes a fallopian tube blocking device comprising a central portion. In order to keep the blocking device in place in the fallopian tube, near t...
