A device for inserting into the vagina of a patient for delivery of a medicament in the vagina. The walls of the tubular member comprising the device are comprised of water-swellable materials having a higher porosity at one end than the other, the relatively low porosity end being positioned distally in the vagina to the relatively high porosity end. The medicament is contained within a reservoir in the tubular member and delivered to the vagina through the pores in the walls of the tubular member at different rates depending upon the porosity. Also provided is a method of delivering a medicament to the vagina of a patient.

An intravaginal device for delivery of a medicament comprising: an elongate, tubular member comprised of a water-swellable, porous material, the length and diameter of said tubular member being selected so as to ensure engagement of the walls of the vagina and retention therein upon swelling of said tubular member when said tubular member is inserted into the vagina of a patient; means for closing one end of said tubular member to form a reservoir within said tubular member for receipt of a medicament to be delivered within the vagina of a patient; and the porosity of the water-swellable, porous material comprising the walls of said tubular member being selectively varied along the length thereof in accordance with whether the medicament within said tubular member is to be delivered to the vagina from the reservoir, retained within the reservoir, or delivered to the vagina from the reservoir and then absorbed by said tubular member.
