Abstract
The wire guide is formed of a flexible stranded wire having a coating extending from the proximal end to rigidify the wire from the proximal end to an intermediate point. The wire remains flexible from the intermediate point to the distal end and a nose is fused to the distal end to prevent fraying of the filaments of the wire.
Claims12
A wire guide for a catheter comprising a length of stranded wire having a flexible section of a diameter of from about 0.008 inches to 0.062 inches extending to a distal end and a rigid section extending from said flexible section to a proximal end and a nose at said distal end of said wire.
A wire guide for a catheter comprising
- a length of stranded wire having a flexible section extending to a distal end and a rigid section extending from said flexible section to a proximal end;
- and
- a metal nose of spherical shape fused to said distal end of said flexible section of said wire.
A wire guide for a catheter comprising
- a flexible length of stranded wire;
- a coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section;
- and
- a nose on a distal end of said wire to protect said wire from fraying at said distal end.
A wire guide comprising
- a length of stainless steel stranded wire of a diameter of from about 0.008 inches to 0.062 inches;
- an epoxy coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section;
- and
- a spherical metal nose integral with said wire at a distal end thereof to retain said wire from fraying thereat.
