摘要

Guide wire, partic. for a drainage or perfusion catheter, has a tip (1) and a tubular section (2) attached to the end remote from the tip, through which a manipulating unit (4) passes. The guide wire tip comprises a spiral wire spring to which a hemispherical end (7) is welded at the tip. External manipulation, the spring windings are relaxed to allow fluid to pass through.
