WIRE GUIDE ENGAGEMENT AND WITHDRAWAL TOOL AND METHOD

摘要

A tool (10) for engaging and withdrawing a wire guide from a patient includes a deformable distal segment (14) having a self-expanding bias such that the distal segment assumes a tortuous configuration, and a control line (40) attached to the distal segment and configured to extend through an intraluminal sheath (18), such that pulling the control line deforms the distal segment in opposition to the self-expanding bias to tighten about a wire guide. The tool may be withdrawn from the patient while tightened about the wire guide, such that the wire guide simultaneously extends out of the patient at each of a first and a second percutaneous entry point.
