Flexible syringe needle

A flexible syringe needle for negotiating through curved body cavities and for irrigating and delivering medications to said body cavities, comprising:

• a flexible hollow needle insertable within a body cavity, said flexible syringe needle extending between a proximal fluid flow connection end and at least one dispensing port, said hollow needle being sufficiently flexible over its whole length to conform to the shape of a selected body cavity and removably connected to said proximal fluid flow connection end permitting replacement of said hollow needle,
• said flexible syringe needle having means for introducing irrigating or medicating fluid into said hollow syringe needle;
• said flexible hollow needle being made of a material capable of flexing back by being deformable from a first predetermined configuration during insertion into the body cavity and returnable to said first predetermined configuration upon removal from the curved body cavity.

An endodontic flexible syringe needle in combination with a syringe for irrigating and delivering medication to an intra-tooth canal, comprising:

• a flexible hollow needle extending from a proximal fluid flow connection end of said syringe, said hollow needle being sufficiently flexible over its whole length to conform to the shape of a tooth canal and removably connected to said syringe permitting replacement of said hollow needle,
• said syringe having means for introducing irrigating or medicating fluid into said hollow syringe needle, and
• said flexible hollow needle being made from a material capable of flexing back to its original shape after being removed from said canal.
