Claim:
1. A positioning device for use during aortic valve implantation surgery, the device comprising: a first extension member having a proximal end and a distal end; a connection member adapted to connect the first extension member to a fixed support; a first coupling having a first portion connected to the connection member and a second portion connected to the proximal end of the first extension member so that the first extension member is moveable in multiple planes relative to the support; at least one reference datum operatively connected to the distal end of the first extension member and extending in a straight line, the reference datum including a rigid rod moveable between a first position and a second position to enable precise locating of the reference datum during the aortic valve implantation surgery; a reference block slidably mounted to the rigid rod and securable at a fixed position along the rigid rod so that the reference block is distal to the distal end of the first extension member and at a spaced distance from the first extension member, the reference block having an attachment mechanism adapted to connect an aortic valve delivery catheter to the reference block; a reference element operatively connecting the distal end of the first extension member to the at least one reference datum; and a second coupling interposed between the distal end of the first extension member and the reference element and enabling the reference element to move in multiple planes relative to the first extension member.
