Aortic valve and conduit graft implant tool

A sizing tool for use in implanting a composite aortic valved conduit having a prosthetic heart valve on a distal end attached to an aortic conduit graft that extends to a proximal end, the aortic conduit graft having an outwardly-bulged distal region adjacent an inflow end and a proximal tubular portion extending to an outflow end coincident with the proximal end of the composite aortic valved conduit, the tool comprising:

• a proximal handle and a shaft extending distally therefrom;
• a prosthetic heart valve sizer affixed to a distal end of the shaft, the sizer having a cylindrical distal portion centered on an axis;
• and
• a replica of the outwardly-bulged distal region of the aortic conduit graft having an axis mounted to slide on the shaft and proximal to the heart valve sizer and adapted to be displaced axially along the shaft from a distal position abutting the heart valve sizer to a proximal position adjacent the handle.

A sizing tool for use in implanting a composite aortic valved conduit having a prosthetic heart valve on a distal end attached to an aortic conduit graft that extends to a proximal end, the aortic conduit graft an elongated tubular proximal section and an outwardly-bulged distal region that mimics native aortic sinuses, the tool comprising:

• a proximal handle and a distal shaft extending distally therefrom;
• a prosthetic heart valve sizer having an axis affixed to a distal end of the shaft;
• and
• an aortic conduit graft replica having an axis mounted on the shaft proximal to the heart valve sizer and having an outwardly-bulged portion that simulates the outwardly-bulged distal region of the aortic conduit graft, wherein the outwardly-bulged portion of the aortic conduit graft replica includes markers thereon to indicate where on the outwardly-bulged portion the coronary arteries would connect to the outwardly-bulged distal region of the aortic conduit graft.

• a proximal handle and a shaft extending distally therefrom;
• a prosthetic heart valve sizer having an axis affixed to a distal end of the shaft;
• and
• an aortic conduit graft replica shaped like the outwardly-bulged distal region of the aortic conduit graft and having an axis mounted on the shaft proximal to the heart valve sizer, wherein the heart valve sizer has a proximal face that has an undulating shape around the sizer axis and the aortic conduit graft replica has a distal face that has an undulating shape around the replica axis that mates with the proximal face of the sizer.
