ABSTRACT:
Tubular pessary as a contraceptive means, which can be carried or worn on either side by hysteroscopy.
The invention relates to a tubular pessary having a contraceptive action through the obturation of the proximal uterine tube in non-surgical manner by hysteroscopy and which can easily be worn on either side.
The tubular pessary has a cylindrical, sensitive central part permitting the obturation of the uterine tube. It has a distal elastic loop, which prevents sliding back into the uterus of the device. It has a proximal elastic loop, which prevents migration of the device into the abdominal cavity and which can easily be removed through a hysteroscope.
The object of the invention is to overcome the inadequacies of the known contraceptive means.
