1. An orientation device for use in mitral valve repair surgery, the device including a catheter which is insertable percutaneously through the mitral valve into a chamber of a heart, the catheter having a distal end configured for entering the heart and a proximal end for manipulating the device, wherein the device includes at least one pressure sensor at or near the distal end of the catheter configured to sense pressures and/or pressure changes at or near the distal end of the catheter during navigation and/or orientation of the catheter within the heart to thereby at least partially indicate a location of the distal end of the catheter within the heart and/or whether the catheter has been properly oriented within the heart so as to not affect the functioning of the mitral valve, and for the device to include two commissural arms at or near the distal end of the catheter, the arms being deployable from a stowed condition, in which the catheter can be introduced percutaneously into the heart, to an operative condition in which the arms extend outwardly in generally opposite directions, each arm being shaped to be locatable within a mitral valve commissure to limit rotational movement of the catheter relative to the mitral valve without affecting the functioning of the valve.
