| abstract |
A device for treating a patent foramen ovale has a first part having a predetermined length; a second part having a predetermined length; a third part having a predetermined length; and a pulling member which penetrates into the second part from a side face of a distal portion of the second part, crosses the second cylindrical part obliquely and extends from a side face of a proximal portion of the second part and penetrates into the third part from a side face of a distal portion of the third part, with one end of the pulling member held by a proximal portion of the first part. A part of a locking mechanism provided at other end of the pulling member and a part of the locking mechanism provided at the third part are locked to each other, when the pulling member is pulled to allow the first part and the second part proximate to each other and the second part and the third part to be proximate to each other. |
