摘要： This invention provides an organ positioning device and method that employs suction to hold organ tissue to the device. The device allows the organ, for example, heart to be positioned in a desired orientation but otherwise allowing movement of the heart as the heart beats. The device is designed to be relatively atraumatic to heart tissue. Generally, the device comprises a resiliently flexible suction head having a plurality of legs that flex to conform to the surface of the heart. The suction head has vacuum passageways in fluid communication with the legs to apply suction between the legs and the surface of the heart.

摘要： An epicardial lead installation tool having an elongated tool body extending between a tool body proximal and distal ends and encloses a tool body lumen. At least one suction pad supported by a suction pad strut extends distally to a distal end surface of the tool body distal end. A lead implantation tool extending between implantation tool proximal and distal ends is inserted through the tool body lumen to dispose the implantation tool distal end proximate to the tool body distal end. The lead implantation tool distal end is adapted to engage the distal electrode head of an epicardial lead to enable the extension of the assembly of the of the lead installation tool, the lead implantation tool and the epicardial lead through a skin incision and to apply the suction pad against the epicardium. Suction is applied through the suction pad to affix it to the epicardium while the implantation tool proximal end is manipulated to affix the distal fixation mechanism to the myocardium at the implantation site.

摘要： This invention provides a system and method for positioning, manipulating, holding, grasping, immobilizing and/or stabilizing a heart including one or more tissue-engaging devices, one or more suction sources, one or more fluid sources, one or more energy sources, one or more sensors and one or more processors. The system and method may include an indifferent electrode, a drug delivery device and an illumination device. The system's tissue-engaging device may comprise a tissue-engaging head, a support apparatus and a clamping mechanism for attaching the tissue-engaging device to a stable object. The system may be used during various medical procedures including the deployment of an anastomotic device, intermittently stopping and starting of the heart, ablation of cardiac tissues and the placement of cardiac leads.
