Method and system for organ positioning and stabilization
First Claim
1. A method of performing an electrode placement procedure on a patient'"'"'s heart, comprising:
- providing a first tissue contact device comprising;
a rigid tissue contact member sized and shaped to fit through a small incision in a region of the patient'"'"'s chest;
an illumination device coupled to the rigid tissue contact member;
a maneuvering apparatus having a rigid shaft and a handle; and
a remotely actuatable joint moveably coupling the tissue contact member to the maneuvering apparatus;
introducing the rigid contact member of the first tissue contact device to the patient'"'"'s thoracic cavity through a small incision in the patient'"'"'s chest;
providing illumination;
actuating the joint remotely from outside the thoracic cavity of the patient;
maneuvering the tissue contact member of the first tissue contact device to position pericardium away from a surface of the heart to create space between the surface of the heart and the pericardium using the first tissue contact device, the space providing exposure of the heart;
providing a second tissue contact device comprising;
a rigid tissue contact member having an ablation electrode; and
a maneuvering apparatus having a shaft and a handle coupled to the rigid contact member;
introducing the rigid contact member of the second tissue contact device into the thoracic cavity of the patient through an incision in the region of the patient'"'"'s chest; and
placing the ablation electrode on or within the exposed heart.

Abstract
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.
