Abstract: A device and method for delivering a bioactive to the uterine wall. In one embodiment, the device comprises a balloon having the bioactive present within the material of the balloon or on an outside surface of the balloon. Another embodiment provides a method comprising inserting the balloon into the uterus, inflating the balloon so that the outside surface of the balloon exerts pressure on uterine wall and delivering the bioactive to the uterine wall.

Abstract: An apparatus for dispensing granular material, such as flux powder to a mold for continuous casting of metal, has an intermediate chamber, a dispensing hopper, and a conduit communicating the interior of the chamber to the interior of the hopper. The conduit has a rotatable auger running through its length, the auger reaching from within the interior space of the chamber into the interior hopper for transferring material from the chamber into the hopper. A dispensing line communicates with a bottom of the hopper at a transfer point for receiving material from the hopper and dispensing the material toward a dispensing end of the line. Pressurized air is supplied to the line, upstream of the transfer point, and a sealing cap is provided for actuating into sealing engagement with a hopper end of the conduit. A second inlet for pressurized air is provided such that air may be supplied directly into the hopper above the fill line.
