Abstract
A system is disclosed for locating positions in the vasculature of a human patient for the purpose of rendering treatment or making a diagnosis therein during a catheterization procedure, such as a procedure to implant an intraluminal arterial graft. The system includes a board which rests under the patient during the procedure which has two markers that can be detected under fluoroscopy. The markers can be moved backwards and forwards along a track in the board to pinpoint various locations in the blood vessel of interest, for example, the points of attachment for the ends of an arterial graft. One of the markers also can be pivoted about the track to represent the angle at which a particular blood vessel is disposed in the patient. The markers can be locked into position with brakes for the duration of the procedure.

3. Apparatus for locating a position in the vasculature of a patient, the apparatus comprising:
-
a non-radiopaque body; a first radiopaque marker disposed in said body; a second radiopaque marker rotatably disposed in the said body; a first positioner means for moving said first marker relative to said second marker; and a second positioner means for moving and rotating said second marker relative to said first marker, said second positioner means adapted to rotate said second marker relative to said first marker independently of moving said second marker relative to said first marker. - View Dependent Claims (4, 5, 6, 7, 8, 9)

10. Apparatus configured to be positioned beneath the body of a patient for use with a catheter to assist in locating a position in the vasculature of a patient for the purpose of making a diagnosis or rendering treatment therein, the apparatus comprising:
-
a board having a first layer and a second layer disposed over the first layer, the first layer having a track configured therein; a marker at least partially formed of a radiopaque material, said marker being configured to move axially along the track of the first layer of said board; and a control cable having a first end attached to said marker for moving said marker along the track of the first layer of said board, said control cable having a second end, wherein the second layer of said board is configured to prevent said marker and said control cable from contacting a patient. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. Apparatus for use in fluoroscopy and configured to be positioned beneath the body of a patient, the apparatus comprising:
-
a board having a first layer and a second layer disposed over the first layer, the first layer having a track configured therein; a first marker including radiopaque material, said first marker being configured to move axially along the track of the first layer of said board; a second marker including radiopaque material, said second marker being configured to move axially along and rotate about the track of the first layer of said board; a first control cable having a first end attached to said first marker for moving said first marker along the track of the first layer of said board; a second control cable having a first end attached to said second marker for moving and rotating said second marker along the track of the first layer of said board; a third control cable having a first end attached to said second marker for moving and rotating said second marker along the track of the first layer of said board; first braking means for locking said first control cable and said first marker into a desired position; and second braking means for locking said second control cable, said third control cable and said second marker into a desired position, wherein the second layer of said board is configured to prevent said markers and said control cables from contacting a patient. - View Dependent Claims (21)
