Abstract

An orientation device (200) for use in mitral valve repair surgery is provided and includes a catheter (202) catheter insertable percutaneously through the mitral valve into a chamber of a heart. At least one pressure sensor (216, 218) and two generally arcuate commissural arms (208, 210) are provided at or near the distal end (204) of the catheter (202). The arms (208, 210) are deployable from a stowed condition, in which the catheter (202) can be introduced percutaneously into the heart, to an operative condition in which they extend outwardly in generally opposite directions. Each arm (208, 210) is shaped to be locatable within a mitral valve commissure and has an indentation (212) shaped to extend, in use, at least partially about a mitral valve commissure to limit movement of the device (200) relative to the mitral valve in the axial direction of the catheter (202).
