Abstract
Abstract A device and method for immobilizing a portion of the epicardium without interrupting the beating of the heart, which includes a frame that can be temporarily anchored to the epicardium and one or more expandable members attached to the frame which, upon inflation, temporarily occlude the passage of blood through the vessel or vessels in the operational field defined by the frame.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
158 words
A device for effectively immobilizing the epicardium of the heart in a specific operational field and for keeping the field free of obscuring blood flow during surgery, the device comprising: a frame for defining an operational field, said frame having a body to which are attached a plurality of anchoring means adapted to anchor said frame to the epicardium, said body having a top surface and, opposite the top surface, a bottom surface adapted to contact the epicardium; and a first expandable member disposed on a first side of said frame, said first expandable member adapted to be connected to an inflation source; wherein said frame is adapted to be secured to the epicardial surface by way of said anchoring means, and the operational field can be kept free of blood flow during surgery by inflating said first expandable member to temporarily stop the passage of blood through portions of vessels within the field defined by the frame.
