MICRO-BRAIDED GUIDEWIRE

摘要

This is a composite guidewire for use in a catheter. It is used in medical procedures that involve accessing specifically targeted inner body areas withoutmajor 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.
