Abstract
An injection system comprising a tube having an inner diameter and an injection needle including a leading edge at one end thereof. A tapered surface is formed between a portion of the tube and the leading edge of the needle. The tapered surface provides a smooth transition surface from the tube to the needle, preventing the needle assembly from plugging when suspended particle materials are used in the injection system and allowing for easy and thorough cleaning of the needle for reuse and/or sterilization.
