Medical injection apparatus

An injection apparatus, comprising

• a hand-held injection facilitation apparatus, which comprises a body that retains a syringe;
• a rod disposed in the body, the rod comprising a distal end that contacts a proximal end of a plunger of the syringe;
• and
• a pivot arm coupled to the rod and extending from the body so that movement of the pivot arm effects longitudinal displacement of the plunger of the syringe.

An injection apparatus for dispensiong a viscous material, comprising

• a transition-bore needle apparatus, which comprises a needle at a distal end of the transition-bore needle apparatus, the needle having an outer diameter, and a proximal and distal end;
• and at least one catheter having a distal end, the distal end of the at least one catheter sealingly attached to the proximal end of the needle so that fluid is displaced through a lumen of the catheter and a lumen of the needle without being displaced between the engagement of the catheter and the needle;
• and
• a hand-held injection facilitation apparatus coupled to the at least one catheter, the hand-held injection facilitation apparatus comprising a hollow body that retains a syringe that is attached to the catheter;
• a longitudinally displaceable rod disposed within the body, wherein a distal end of the rod contacts a proximal end of a plunger of the syringe;
• and a pivot arm coupled to the rod and extending from the body so that movement of the pivot arm causes longitudinal movement of the plunger of the syringe.
