DEVICES AND METHODS FOR MANIPULATION OF ORGAN TISSUE

摘要

The invention provides techniques for holding a moving organ, such as a beating heart (10). A manipulation device (12) that holds the organ includes an outer shell (16) and an inner shell (14). Vacuum pressure applied to the outer shell draws the organ into the inner shell. The vacuum pressure is communicated to the inner shell chamber via one or more apertures (58) in the inner shell. The inner shell may have a structure and a texture that enhances the hold on the organ, and the manipulation device may also include a skirt-like member (18) to improve the seal between the manipulation device and the organ.
