Abstract
Alternative designs, materials and manufacturing methods for connecting different guidewire sections together.
Claims24
A guidewire, comprising:
- a proximal section having a distal end, wherein the distal end of the proximal section has a reduced size;
- a distal section having a proximal end, wherein the proximal end of the distal section has a reduced size, and wherein the proximal end of the distal section overlaps the distal end of the proximal section;
- and
- a connector disposed adjacent the distal end of the proximal section and the proximal end of the distal section, the connector adapted and configured for permanently joining the proximal section to the distal section.

A guidewire, comprising:
- a proximal section having a distal end, wherein the distal end of the proximal section includes a flexibility transition region;
- a distal section having a proximal end, wherein the proximal end of the distal section includes a flexibility transition region;
- and
- a connector disposed adjacent the distal end of the proximal section and the proximal end of the distal section, the connector adapted and configured for joining the proximal section to the distal section.

A method of manufacturing a guidewire, comprising the steps of:
- providing a proximal section having a distal end, and a flexibility transition region at the distal end;
- providing a distal section having a proximal end, and a flexibility transition region at the proximal end;
- and
- joining the flexibility transition regions.
1 more element
A guidewire, comprising:
- a proximal section having a first flexibility;
- a distal section having a second flexibility;
- and
- means for joining the proximal section with the distal section such that the first flexibility and the second flexibility are blended.
