Abstract:
1. A device for measuring a depth of insertion into a heart, comprising: an elongate tubular body having a proximal end configured for insertion into the heart, a distal end, a first lumen extending at least partially therethrough, and a second lumen adjacent the first lumen, the second lumen being configured to receive a conduit to be placed between a heart chamber and a coronary vessel; an access port near the proximal end of the elongate tubular body; an opening near the distal end in flow communication with the access port; and at least one depth indication mechanism visible from the outside of the tubular body for indicating a depth of insertion of the device, at least one depth indication mechanism visible from the outside of the tubular body for indicating a depth of insertion of the device, wherein the device is configured so that when the device is inserted into the heart and reaches a blood-containing portion of the heart, blood flows through the access port and the opening and the depth indication mechanism indicates the depth of insertion of the device.
