Definitions

  • the mass of hardened material that is used to join the proximal and distal cores may be any bonding material, including the following: solder, brazes, epoxies, glues, laser welds, spot welds, etc. that are preferable for the wire type and provide the required functional attributes. Joining the two cores together can be accomplished by dispensing, for example, solder in-between the connecting ends and/or encasing the connecting ends with solder. '
  • the present invention method of joining a proximal and a distal core section can be applied to any two wires, and to any guide wire having a diameter ranging from about 0.006 to 0.040 inch.
  • FIG. 2 is a partial perspective view of the tip of a D-shaped distal end of one of the core sections of the guide wire.
  • FIG. 3 is a partial, side elevational view depicting the complementary distal end of the proximal core section and the proximal end of the distal core section, aligned with one another with a gap therebetween.
  • FIG. 5 is a partial, side elevational view of the guide wire in FIG. 3 with tapered backsides.
  • FIG. 8 is a partial, side elevational view of the guide wire in FIG. 7 with a tapered backside.
  • the complementary shape of the connecting ends 28 and 32 is a D-shape cross-section 40.
  • the D-shape has a semicircular shape with a straight edge.
  • Other cross-sectional shapes such as ovoids, triangles, trapezoids, rectangles, and similar polygons are contemplated.
  • FIG. 6 embodiment provides a more gradual transition from the proximal core section 24 to the distal core section 30 and therefore is beneficial when using wires with dissimilar bending forces. It is also conceivable to have another embodiment, where both the front and back sides of the connecting ends have a taper, such that the distal end of the proximal core section has opposed, imaginary planes converging in a proximal direction, and the proximal end of the distal core section has opposed, imaginary planes converging in a distal direction.
  • FIG. 7 shows another embodiment where the connecting ends 28 and 32 include a serrated profile 52 at the interface where the ends engage.
  • the core sections 24 and 30 are placed in the fixture so that there is a small gap 38 between the connecting ends 28 and 32 for solder, or other bonding material, to wick into, and then bond and secure the two core sections together.
  • the solder or other bonding material may also encase the connecting ends 28 and 32 to provide a stronger bond.
  • the joined proximal and distal core sections 24 and 30 are ground to a required outer diameter.
  • the actual final grind diameter depends upon the design needs of the specific guide wire.
  • an optional polymer coating may then be applied to at least a portion of or the entire the core 22.
  • the finished guide wire has a smooth cross-sectional profile at the joint from the proximal core section 24 to the distal core section30.
  • the tapered D-shaped cross-section 40 may be ground into the connecting ends 28 and 32.
  • serrations 54 may be formed by grinding.
  • the connecting ends 28 and 32 are plunge ground to provide a constant or tapered smaller diameter.
  • this constant or tapered smaller diameter is approximately 1 cm long, but may be 0.5 to 5 cm long.
  • an additional step may be taken where the plunge grind on the ends 28 and 32 is then tinned or etched for improved solderability.
  • the plunge ground cores 24 and 30 are then placed in a fixture in opposing directions so that the connecting ends 28 and 32 overlap one another.
  • solder or other bonding material is applied along the overlap to join to the two cores 24 and 30.
  • the joined cores 24 and 30 are then ground to a required outer diameter. This final grind diameter is dependent upon the design needs of the specific guide wire. Once the final grind is complete, a polymer coating may then be applied to the core 22 or the guide wire 20.
