Patent

CA 2463536

Devices for and methods of moving, manipulating, or holding an organ of the body, particularly a heart, are disclosed. A manipulating device includes a seal member, which includes two or more protrusions, that adheres to the surface of the organ when vacuum pressure is applied to a chamber defined by an inner surface of the seal member. The seal member may be made of a substantially compliant and flexible material. The protrusions may enable the seal member to more easily conform to the irregular shape of the organ, may accommodate patient-to-patient variations in the size and shape of organs, may increase the strength of the attachment between the seal member and the organ, may reduce the likelihood of damage to the surface of the organ and may expose areas of the organ for surgical procedures.

L'invention concerne des dispositifs et des procédés servant à déplacer, manipuler ou tenir un organe du corps, notamment un coeur. Un dispositif de manipulation selon l'invention comprend un élément de fixation, pourvu de deux ou de plusieurs protubérances, qui adhère à la surface de l'organe lorsqu'une pression négative est appliquée à une chambre définie par une surface interne de l'élément de fixation. L'élément de fixation peut être constitué d'un matériau pratiquement souple et flexible. Grâce à ses protubérances, l'élément de fixation peut se conformer plus aisément à la forme irrégulière de l'organe et s'adapter à des variations dans la taille et la forme des organes entre patients ; elles permettent également d'augmenter la force de la liaison entre l'élément de fixation et l'organe, de réduire le risque d'endommagement de la surface de l'organe et d'exposer des zones de l'organe en vue de procédures chirurgicales.
