Abstract
A catheter assembly comprising a needle received within a catheter. The needle has a solid tip and a hole in the cylindrical wall of the needle that communicates with the internal passageway of the needle. The needle is received within the lumen of the catheter, the catheter having a hole in its side wall that aligns with the side hole of the needle. Alignment of the side holes is provided by complementary alignment features on the proximal ends of the needle and catheter. The needle may be connected to a flash chamber for observation of fluid from the cavity. Fluid does not flow into the needle without first entering the side hole of the catheter. Observation of fluid in the flash chamber will not occur until the side hole of the catheter contacts the fluid. This side entrance provides positive indication that the distal end of the catheter has entered the cavity.
