Title:

SPACE-SECURING DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/037068

Kind Code:

A1

Abstract:

In a pericardial endoscopic procedure, a space required for handling an endoscope or a treating instrument can be secured, without providing a specific space-securing means to the endoscope or treating instrument or without unnecessarily dilating the pericardiac cavity, so as to improve the handling properties while preventing the onset of a complicating disease such as cardiac tamponade. Disclosed is a space-securing device comprising a pericardium-pressing part for pressing the pericardia from the pericardiac cavity side, a heart-pressing part for pressing the heart surface from the pericardiac cavity side, and a connecting part for connecting said pericardium-pressing part with said heart-pressing part, wherein the connecting part generates an elastic force allowing the dilation against the pressures applied by the pericardia and heart to thereby form a space between said pericardium-pressing part and said heart-pressing part.
