Patent

CA 2471275

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.

L'invention concerne de manière générale des dispositifs et des techniques servant à maintenir un organe, tel que le sommet (14) d'un coeur (10) qui bat. Certaines formes de réalisation de l'invention concernent des dispositifs comprenant un dispositif de manipulation (12), une tige support (20) et un mécanisme de couplage (24) permettant de coupler le dispositif de manipulation à la tige support. Ce mécanisme de couplage comprend généralement des éléments d'assemblage. Ces derniers peuvent être inclus dans le dispositif de manipulation et/ou la tige support. Une fois couplés, les éléments d'assemblage empêchent la séparation du dispositif de manipulation et de la tige support. Les éléments d'assemblage peuvent aussi présenter un degré de liberté en rotation, et, dans certaines formes de réalisation, peuvent comporter un état verrouillé en rotation et un état déverrouillé en rotation.
