ABSTRACT:
A needle for use with an apparatus for injecting fluid into a pierced body orifice has a hollow body having an axis and an internal bore along the axis, a blunt, closed first end, an open second end with an interface to a closure for attachment to a reservoir, and one or more side openings at substantially a right angle to the axis communicating from the internal bore to outside the hollow body. The needle may be curved or straight. A fluid injection system based on the needle uses such as squeeze bottles or syringes to express material through the needle. In another aspect a treatment apparatus for treatment of a pierced body orifice has a hollow body having an inner bore and first openings through walls of the body from the inner bore to outside the body, a reservoir communicating with the inner bore of the hollow body via at least one second opening in the hollow body; and an expression mechanism whereby volume of the reservoir may be reduced, expressing fluid from the reservoir through the second opening and the inner bore, and out of the first openings. Various expression mechanisms are usable.
