By then operating one or more actuators for a proximal handle 30 by one hand, the contraceptive device 12 can be expanded to make a large profile to be engaged with a peripheral tissue. Since the other hand is kept free for examination with a hysteroscope, the number of medical workers necessary for deployment of the contraceptive device 12 can be minimized.;COPYRIGHT: (C)2009,JPO&INPIT
