Abstract
Abstract A method for manipulating a tissue structure within a thoracic cavity of a patient includes the step of providing a tissue positioning tool having a shaft, a tool support apparatus and a tissue supporting member releasably connectable to the shaft. The tool support apparatus includes a clamp assembly configured to secure the shaft to the tool support apparatus. The tool support apparatus is positioned on an outer surface of a patient's chest and at least a portion of the shaft and the tissue supporting member are introduced into the patient's thoracic cavity. The tissue supporting member is attached to the portion of the shaft that is disposed within the patient so as to contact a tissue structure. A force is applied to the shaft to displace the tissue structure and the shaft is locked to the tool support apparatus with the clamp assembly.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
163 words
A method for manipulating a tissue structure within a thoracic cavity of a patient, comprising the steps of: providing a tissue positioning tool having a shaft, a tool support apparatus, and a tissue supporting member releasably connectable to the shaft, the tool support apparatus having a clamp assembly configured to secure the shaft to the tool support apparatus; positioning the tool support apparatus on an outer surface of a patient's chest; introducing at least a portion of the shaft and the tissue supporting member into the patient's thoracic cavity; attaching the tissue supporting member to the portion of the shaft disposed within the patient; contacting a tissue structure in the thoracic cavity with the tissue supporting member; applying a force to the shaft so that the tissue supporting member moves the tissue structure to a displaced position; and locking the shaft to the tool support apparatus with the clamp assembly after the applying step so that the tissue structure maintains the displaced position.
Claim 2
Independent Claim
