(b) a slidable plunger assembly disposed within said syringe body and extending through said first end;
(c) an elongated hollow barrel mounted to said coupler, said barrel including a passageway in fluid communication with said coupler and one or more openings adjacent the end of said barrel opposite said coupler and in communication with said passageway, said barrel formed in the shape of a Van Buren curve; and
(d) a meatal obstructor slidably mounted around said barrel, whereby said barrel may be inserted into the entire length of a patient'"'"'s urethra and then said barrel may be withdrawn while simultaneously applying an anesthetic to the urethra through said openings, and wherein said obstructor may be positioned against the external orifice of the urethra while said barrel is withdrawn, thereby preventing said anesthetic from escaping from the urethra.

Abstract
Instruments for anesthetizing the urethra of male and female patients are disclosed.
The male instrument includes a standard syringe with an elongated hollow barrel mounted on the syringe. The barrel is formed in the shape of a Van Buren curve and includes one or more openings near its tip. The male instrument also includes a metal obstructor slidably mounted around the barrel. The barrel is adapted to be inserted into the entire length of a patient'"'"'s urethra and is then withdrawn while simultaneously applying an anesthetic through the openings and maintaining the obstructor against the external orifice of the urethra.
The female instrument includes a solid anesthetic suppository attached to one surface of a metal obstructor and a handle attached to another surface of the obstructor. The suppository is formed in the shape of an anatomical female infrapubic curve. The suppository is inserted into the urethra and anesthetizes the entire urethra as the suppository dissolves.
