Abstract
A composite guidewire comprising a proximal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the distal end being formed with a first flat planar bonding face which extends parallel to the longitudinal axis, the proximal wire segment having a first elasticity; a distal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the proximal end being formed with a second flat planar bonding face which extends parallel to the longitudinal axis, the distal wire segment having a second elasticity; wherein the first and second flat planar bonding faces of the proximal wire segment are formed complementary to one another; and further wherein the proximal and distal wire segments are joined together by bonding the first flat planar bonding face to the second flat planar bonding face in an overlapping manner and a method for forming a composite guidewire.
