ABSTRACT:
An elongated syringe for administering a substance to a patient includes an elongated syringe chamber that may be inserted into a duct of a patient without unwantingly injuring the patient, a needle extending from the distal end of the syringe chamber, and a plunger rod extending from the proximal end of the syringe chamber. The syringe chamber may be flexible to accommodate curvatures of the duct of the patient. The syringe chamber includes a plurality of chamber compartments that will contain a fluid. At least one of the chamber compartments contains a fluid that is administered to a patient. The syringe chamber may include a driving piston located between two or more chamber compartments. The needle of the syringe may be a component of a transition-bore needle apparatus to facilitate delivery of a relatively viscous fluid from the syringe. The needle may also be flared at its proximal end so that the diameter of the proximal end of the needle is greater than the diameter of the distal end of the needle. Methods of using an elongated syringe are disclosed.
