Fig. 1 A, Larger helical coil, not mounted. B, Cross-section of helical coil. C, Smaller helical coil, not mounted. D, Helical coil with added control tube. E, Turning control tube decreases or increases diameter of helical coil. Linear pull or push of control tube renders pitch of the coil smaller or greater. F, Helical coil with added control tube, mounted onto Swan-Ganz catheter, coiled up and ready for insertion through introducer sheath.
