Abstract
A guidewire extender particularly suited for use in percutaneous transluminal coronary angioplasty. A tubular connector member attaches to the proximal end of a steerable guidewire. A helical coil bonded to a male insertion segment of a proximal extension member contacts an inward depression on the tubular connector. The extension member mates with the tubular connector to extend the guidewire by rotating the extension member to advance the helical coil past the depression. Some axial play between the coupled components is possible. The extension member locks to the guidewire without special tools. Manufacture and assembly are simplified.
