An insertion guide wire with an anchor formed in the distal end for precisely locating a subcutaneous arterial wound and guiding a plug of hemostatic material thereto. When the hemostatic material is properly placed, the anchor can be released and the guide wire removed, leaving no foreign object in the lumen of the artery.

[ What is claimed is:] [1.] A guide wire, comprisinga sheath having a longitudinal axis, a proximal end, a distal end and a lumen extending from said proximal end toward said distal end;an aperture formed in an intermediate portion of said sheath at a spaced distance from said distal end, said aperture delimiting a distal portion of said sheath between said distal end and said aperture;a core wire slideably arranged in said sheath and having a proximal end and a distal end, said core wire being movable between a first position in which an intermediate portion of said core wire between said proximal and distal ends protrudes from said sheath through said aperture to form a loop and said distal portion of said sheath forms an angle of less than about 180.degree. with a remaining portion of said sheath, said loop and said distal portion of said sheath in said first position of said core wire each having a component projecting in a direction transverse to said longitudinal axis, and a second position in which said intermediate portion of said core wire is substantially entirely within said lumen of said sheath, whereby movement of said core wire from said first position to said second position eliminates said loop and moves said distal end of said sheath into substantial alignment with said longitudinal axis.
