Ex-vivo study of coaxial snaring of a small-bore catheter fragment (5-F).
A. Simple snaring of the catheter fragment also causes an angulation problem.
B. Coaxial snaring reduces the angle between the catheter fragment and the snaring catheter. Note that the guidewire was positioned through the lumen of the catheter fragment.
C. There is smooth engagement between the catheter fragment and the 10-F sheath.
