Abstract

This is a composite guidewire for use in a catheter. It is used in medical procedures that involve accessing specifically targeted inner body areas without major surgery. The composite guidewire is especially useful for accessing peripheral soft tissue targets. The guidewire may be a multi-section guidewire assembly preferably having super-elastic alloy ribbon braided reinforcements along at least a portion of the core. The guidewire core may be of a stainless steel or a high elasticity metal alloy, preferably a Ni--Ti alloy. A variation of the guidewire also preferably includes a braid on the exterior of the core wire with an exterior polymeric coating to the most distal portion of the assembly and preferably assembled using adhesives such as epoxies.
