Abstract
An applicator useful for the administration of viscous or gel-type drugs to the human urethral tract. The applicator tip has an end through which the medicinal gel is expelled. Adjacent the end, is a cylindrical portion. Both the end and the cylindrical portions are of such size as to be receivable in the urethral tract. Above the cylindrical portion is a tapered zone which extends to the barrel and has its largest external diameter at the barrel. This tapered portion is only partially receivable in the urethral tract so as to seal the urethral tract during injection of the drugs.
