The block comprises a solid body of solidified plastic material having a transverse dimension conforming to the interior of the oviduct and having at one end a solid molded tip portion with a configuration adapted to fit in contact with the uterine end of the oviduct of a female forming a single unit. The molded tip portion has a transverse dimension larger than the interior of the oviduct to prevent the block from migrating into the intraperitoneal cavity, whereby the tip portion remains accessible from the uterine cavity, the molded tip portion having means thereon which can be gripped by mechanical means to remove the oviduct block non-surgically. The body of plastic material has a length providing a volume sufficient to block the passage of ovum through the oviduct to the uterine cavity of the female.</p> |
