Claim:
1. A system for treating a vein, the system comprising: a syringe containing a vein-occluding substance; an injector for delivering the vein-occluding substance into the vein, the injector comprising a removable adapter having a proximal end and a distal end configured to mate with the syringe, the removable adapter defining a central lumen with openings at the proximal end of the removable adapter and the distal end of the removable adapter, the removable adapter configured to be at a distal end of the injector, the injector further comprising a movable wall and an actuator configured to move the movable wall a predetermined distance within the central lumen of the removable adapter upon activation of a control, the movable wall being configured to push a proximal end of the syringe within the removable adapter, the injector being operably connectable to the control, wherein activation of the control causes the injector to deliver a bolus of between about 0.05 milliliters (mL) and 3 mL of the vein-occluding substance from the syringe into the vein, wherein the injector is configured to automatically deliver a plurality of substantially equal spaced-apart boluses of the vein-occluding substance when the actuator moves the movable wall the predetermined distance, thereby expelling the bolus of vein-occluding substance from the syringe when the syringe is mated with the distal end of the removable adapter; and a catheter having a proximal end, a distal opening, and a sidewall, the proximal end of the catheter being configured to be operably connected to the injector via the syringe when the syringe is mated with the distal end of the removable adapter, wherein the catheter is configured to advance distally across a treatment zone in the vein.
