Abstract
A mold is used to form a solder joint to join the distal end of the guidewire to a wire coil. The mold has a cavity that can have different configurations so that the solder joint can be any of bullet shaped, micro-J shaped, cone shaped, truncated cone shaped, or have a textured surface.
Claims13
A method of making a mold for use in forming a solder joint on a guidewire, comprising:
- providing a mold;
- machining a cavity into a first mold section and a second mold section;
- machining the cavity into a micro-J shape for a distal end of the guidewire so that the cavity in the first mold section is a mirror image of the cavity in the second mold section;
- and
- wherein the cavity terminates at one end in an opening on an exterior portion of the mold, the opening being configured to receive the distal end of the guidewire and coils on the distal end of the guidewire.
2 more elements
A method of making a mold for use in casting a pre-shaped solder distal tip on the distal end of a guidewire, comprising:
- providing a mold blank formed of a material able to withstand the temperature required to receive molten solder;
- machining a cavity of micro-J shape for a guidewire into the mold blank, the cavity terminating at one end in an opening on an exterior portion of the mold blank, the opening being configured to receive the distal end of the guidewire.
