<p>In general, the invention provides devices and techniques for holding an organ, such as the apex (14) of a beating heart (10). Some embodiments of the invention are directed to devices that include a manipulating device (12), a support shaft (20) and a coupling mechanism (24) that couples the manipulating device to the support shaft. In general, the coupling mechanism includes mating components. The mating components may be included in the manipulating device and/or the support shaft. When coupled, the mating components resist separation of the manipulating device and the support shaft. The mating components may also allow a degree of rotational freedom, and in some embodiments, may have a rotationally locked configuration and rotationally unlocked configuration.</p> |
