Patent ID: 7524303

Claim:
A kit for performing an angioplasty, stenting, or clot removal procedure in a blood vessel, comprising: a first component comprising: a first catheter having a wall enclosing an axial lumen, the first catheter having a distal end and the wall having a substantially circularly cylindrical inner surface and being provided with at least one blood inlet opening spaced from the distal end, at least one blood outlet opening in proximity to the distal end, a fluid delivery and suction opening located between the blood inlet and outlet openings, the blood inlet opening and blood outlet opening communicating with the axial lumen and forming with the axial lumen a blood bypass flow path, and a fluid delivery and suction lumen communicating with the fluid delivery and suction opening; a first blocking balloon carried by the first catheter at a location between the blood inlet opening and the blood outlet opening; and an expandable blood vessel dilation device carried by the first catheter at a location between the blood inlet opening and the blocking balloon; and a second component composed of a first guide wire having a distal end and provided with a blocking structure at or near the distal end, said first guide wire being insertable through said axial lumen of said first catheter and said blocking structure being dimensioned to be movable through and along said axial lumen but to substantially impede blood flow through said axial lumen when said blocking structure is positioned between said blood inlet opening and said blood outlet opening; and a third component comprising: a second catheter having a thin, imperforate wall enclosing an axial lumen, the second catheter having an open distal end; a hollow tube dimensioned to surround, and to be movable longitudinally with respect to, the second catheter; and a second blocking balloon carried by the hollow tube.
