摘要:
A system and method for providing a vascular image are disclosed wherein a single composite display simultaneously provides a first view of a patient including an angiogram image and a second view including an intravascular image rendered from information provided by an imaging probe mounted on a distal end of a flexible elongate member. A cursor, having a position derived from image information provided by a radiopaque marker proximate the imaging probe, is displayed within the angiogram image to correlate the position of the imaging probe to a presently displayed intravascular image and thus provide an easily discernable identification of a position within a patient corresponding to a currently displayed intravascular image. The resulting composite display simultaneously provides: an intravascular image that includes information about a vessel that is not available from an angiogram and a current location within a vessel of a source of intravascular image data from which the intravascular image is rendered.
摘要:
Sheath assemblies incorporating slotted structures at one or more areas provide areas of different flexibility and bendability characteristics along the length of the sheath assembly. An inner tubular member has an arrangement of discontinuous slots along at least a portion of its length, with at least some of the slots terminating in an enlarged aperture at at least one terminus of the slot, and a flexible outer tubular member contacts and extends over at least a portion of the inner tubular member.
