CA 2398220

Devices and methods of manipulating and stabilizing organ tissue, such as heart tissue. The devices, which are of varying sizes, shapes and conformations, generally include a seal member having a chamber with a wall and a skirt-like member that extends outward from the chamber wall for contact with a surface of an organ. The skirt-like member is substantially compliant and tacky, thereby promoting adhesion with the organ surface. Adherence of the device to the tissue may be enhanced by the mechanical or hydraulic application of vacuum pressure. The methods describe steps for manipulating, including moving, lifting, immobilizing, turning and reorienting organ tissues. Additional methods describe steps for manipulating the heart.

L'invention porte sur des dispositifs et procédés de manipulation et d'immobilisation de tissus d'organes tels que ceux du coeur. Ces dispositifs de diverses tailles, formes et conformation comprennent en général un élément étanche présentant une paroi et un élément en forme de jupe, prolongeant la paroi et destiné à entrer en contact avec la surface de l'organe, et substantiellement souple et collant de manière à en favoriser l'adhérence avec ladite surface, laquelle peut être renforcée par l'application d'une dépression à l'aide d'un moyen mécanique ou hydraulique. Les procédés décrivent les étapes de manipulation, y compris le déplacement, le soulèvement, l'immobilisation, la rotation ou la réorientation des tissus d'organes, et en particulier des procédés de manipulation du coeur.
