AUTOMATED INJECTION CATHETER DEVICE AND SYSTEM

摘要

A device and system for automating catheter needle injection has a first actuator that extends a needle past the distal end of the catheter, a second actuator that depresses a plunger to deliver injectate through the needle and an agitator assembly to agitate the injectate before it enters the needle. The device and system may also include a force sensor coupled to the plunger to sense pressure to detect occlusion, and an optical sensor to sense movement of the second actuator.
