New coaxial exchange guide wire with a variable-length tip.
A new coaxial exchange guide wire, which has a variable-length, flexible "J"-shaped tip for exchanging drainage catheters in both large and small structures, is described. The design provides a gradual transition from the softness of the tip to the stiffness of the cannula. The system is presently available in two sizes (0.89 mm [0.035 in.] and 0.64 mm [0.025 in.]) and can also be used as a catheter end-hole dilator.
