An implant delivery syringe 10, 100 includes a barrel 18, 118, a plunger assembly 12, 112, and a barrel adapter 20, 120. A barrel adapter 20, 120 mountable to a syringe barrel 18, 118 includes a barrel tip 32, 132, needle retraction mechanism 21, needle assembly 42 and stylet 54, 154 slidably disposed within the needle lumen 29. The needle retraction mechanism 21 includes a biasing member 30, 130, actuable locking arrangement 31 and locking mechanism 22, 122. When the actuable locking arrangement 31 is actuated, the biasing member 30, 130 causes the needle 28, 128 to axially translate over the stylet 54, 154 during retraction to cause delivery of an implant 49, 129 to a target location. The stylet 54, 154 may be retracted following delivery. Methods of assembling, manufacturing, and using are also provided. |
