Abstract: A two-stage device for use within the canal of the cervix of the uterus for the dual and simultaneous purposes of venereal disease prevention and of contraception by prohibiting the migration of sperm through the cervical canal. The two-stage device will consist of (Part A) an insertable member which will be inserted into and be maintained within the cervical canal to which (Part B) a temporary member, effective for upward of a year, can be attached easily with a minimum of discomfort to the patient. [Either or both parts of this two-stage device (at present most probably the temporary part) can incorporate metals such as copper, silver, or others, or suitable compounds thereof, and also spermicidal and pathogenocidal agents, steroids or other drugs.]A unique feature of the invention is its placement within the cervical canal rather than in the fundus or vagina.
