Blocking device (1) for a Fallopian tube and introduction device (20) thereof. The blocking device (1) consists of a central section (2) with adjoining elongated retaining means (3) on both sides thereof which are displaceable between an introduction position and a retaining position. In the introduction position, the retaining means (3) are in line with the central section (2). The introduction device (20) consists of a construction comprising a handle (21), central bush (22) and sliding bush (25), as a result of which it is possible, on the one hand, to displace the blocking device (1) over a defined distance accommodated inside an introduction sleeve when it comes into contact with the constriction of the Fallopian tube, and, on the other hand, to allow the blocking device (1) to unfold without further displacement after it has been fitted in the correct position. |
