Abstract

A surgical tool for measuring a perimeter of a heart at a location spaced from an apex of the heart includes a handle having a head having first and second sides. The head is adapted to be placed against the heart at the measurement location with the sides spaced apart along the perimeter. The head has a first slot formed in the first side communicating with an interior of the handle. The handle has a proximal end opposite the head. A second slot is formed in the proximal end communicating with the handle interior. The handle has a visibly perceptible handle marking adjacent the second slot. An elongate flexible member has a first end secured to the handle and extending from the second side of the head. The elongate flexible member is passed through the first and second slots and terminates at a free end external of the handle. The elongate flexible member has a plurality of tape markings disposed along a length of the elongate flexible member. The elongate flexible member extends out of the second slot at the handle marking for the tape markings to be in alignment with the handle marking as the flexible member is pulled through said the slot.
