Abstract
An cervical drug delivery apparatus having an absorbent cylindrical structure with a cervical cap attached to one end. One or more therapeutic agents are applied to the internal surface of the cervical cap. The cervical drug delivery apparatus is housed within an applicator and inserted into a patient's vagina. Upon deployment of the cervical drug delivery apparatus, the cervical cap is automatically positioned over the patient's cervix providing for the direct application of the therapeutic agents on the patient's cervix. Alternative features of the cervical drug delivery apparatus include, a break-away cylindrical structure, a collapsible support structure for the cervical cap, an inflatable means for supporting the cervical cap, and the ability of the cylindrical structure and/or the cervical cap to contain one or more therapeutic agents that can be delivered by outside means.
