Abstract
Devices and methods are disclosed that provide a syringe actuator device for use in the distention and irrigation of a body conduit before the use in a medical procedure such as a coronary bypass graft procedure. The device can be retrofit to a syringe by attaching it to the cap of the plunger and engaged to automatically apply pressure to fluid in the syringe. In some embodiments, elastic bands attached to the device are easily engaged or removed from a syringe during a procedure to limit the pressure on the syringe to various levels. The device may be overridden by an operator pushing on the plunger of the syringe as in normal syringe operation.

A method for preparing a conduit, the method comprising:
- providing a syringe having a plunger flange and a barrel flange, wherein the plunger flange has at least one elastic band attached;
- filling the syringe with fluid;
- connecting the conduit to the syringe;
- attaching the at least one elastic band to the barrel flange of the syringe to apply pressure to the fluid in the syringe to flush the conduit;
- and
- tying or clipping branches of the conduit to stop leaking.
A kit for preparing a conduit, the kit comprising:
- a syringe having a plunger flange and a barrel flange;
- and
- a syringe actuator device comprising a cap having a recess for securing the cap onto the plunger flange of the syringe and at least one elastic band attached to the cap, wherein the at least one elastic band is configured to attach to the barrel flange of the syringe to apply pressure to fluid in the syringe.
