DISPOSITIF POUR LA CONTRACEPTION TUBAIRE, REVERSIBLE, PAR HYSTEROSCOPIE

摘要

The contraceptive pessary has a central tubular section (1) made from a soft bio-compatible material. The central section has a slot at its proximal end to accept the tip of an introducer (15). Extending from the proximal end of the central section is a loop (11) of surgical fibre material which is sprung, so as to assure a hoop shape. At the distal end of the central section is a similar extending loop of fibre material (6). The two extending loops and the central section are contained within a hysteroscope (8) which is introduced into the womb. The introducer is then used to push the device clear of the hysteroscope. Once in position, the distal loop springs apart acting as a retainer. The proximal loop can be used for retraction.
