Abstract
A process for joining two discrete wire components without the need of a third component, wherein material from the end of one wire component is removed to form a female end and the end of the other wire is formed into a male end. The male may be secured within the female end by conventional means. The female end may be formed by electrical discharge machining or laser drilling.
Claims3
A guidewire comprising an elongated proximal core portion having a female end disposed at a distal extremity of the proximal core portion formed from a first continuous material;
- a distal core portion having a male end disposed at a proximal extremity of distal core portion, with the male end permanently secured within the female end;
- a flexible body member disposed about and secured to the distal core portion;
- and a shapable member secured to the distal core portion and extending through the flexible body member.
A guidewire comprising an elongated proximal core portion having a male end disposed at a distal extremity of the proximal core portion formed from a first continuous material including stainless steel;
- a distal core portion having a female end with a predetermined depth disposed at a proximal extremity formed from a second continuous material including a nickel-titanium alloy, with the male end permanently secured within the female end;
- and a flexible body member disposed about and secured to the distal core portion.
A guidewire comprising a proximal section having an outer diameter smaller than 0.04 inch, and having a female end of a predetermined depth disposed at a distal end of the proximal section;
- and a distal section having an outer diameter smaller than 0.04 inch, and having a male end disposed at a proximal end of the distal section, with the male end permanently secured within the female end such that the guidewire forms a joint having an outer diameter that is substantially the same as the outer diameter of the female end, wherein the joint has a smooth, continuous outer surface at a transition point.
