GUIDANCE DEVICE FOR ULTRASONOGRAPHY GUIDED DEVICE PLACEMENT

摘要

A guidance device for ultrasonographic guidance of percutaneous placement of an intravascular introducer in a subject adapted for placement against the body of the subject essentially at a desired percutaneous insertion site is disclosed. A directing member is oriented such that the trocar or introducer received in the directing member provides for insertion of the trocar or introducer along a first axis. The guidance device is adapted to receive and releasably hold an ultrasonographic imaging probe such that a first axis of the directing member is positioned in a plane that is essentially perpendicular to and transversely crossing the imaging plane, and the directing member is coupled to the guidance device via an attachment member such that the directing member is configured to be movable only in the plane that is essentially perpendicular to the imaging plane.
