Abstract
A surgical method for assisting a malfunctioning heart comprises inserting a balloon into an intrapericardial space and inflating the balloon in the intrapericardial space to place a compressive pressure on a heart in the intrapericardial space sufficient to force blood from the heart. A lubricant is fed to the intrapericardial space after insertion of the balloon into the space.
Claims20
A surgical method for aiding a malfunctioning heart, comprising:
- providing an inflatable balloon in a collapsed configuration;
- inserting said balloon into an intrapericardial space about a heart disposed in said space;
- inflating said balloon in said intrapericardial space to place a compressive pressure on the heart sufficient to force blood from the heart;
- and
- feeding a lubricant to the intrapericardial space after insertion of said balloon into said space.
2 more elements
