Estimating the term…
A medical guidewire system including an inner member having an outer diameter and an outer member having an inner diameter, the inner diameter being larger than the outer diameter. The inner and outer members are relatively slidable to adjust a stiffness of the guidewire system. The lumen of the outer member forms a gap for fluid flow therethrough. A connector has a first end portion connected to the outer member, a second end portion connected to the inner member and a fluid infusion channel communicating with the gap for injection of fluid through the gap to exit a distal portion of the outer member.
A medical guidewire system comprising a first inner member having a first outer diameter, a second intermediate member having a second outer diameter larger than the first outer diameter, and a third outer member having a third diameter larger than the second outer diameter, the second member having a longitudinally extending opening to receive the first member for relative sliding movement with respect to the first member, the third outer member having a longitudinally extending opening to receive the second member for relative sliding movement with respect to the first and second member, the second member having a flared portion to engage the third member for an interlocking frictional engagement, and the first and second members have a clamping engagement.
