Tissue closure and tissue closing device
First Claim
1. A tissue closure for closing a punctured portion on a wall of a blood vessel, comprising:
- a plate-shaped anchor portion adapted to be held at and around the punctured portion from one side of the wall of the blood vessel;
a deformation portion comprising a frame-shaped body, the deformation portion being deformable between a first form in which the body is elongated in a direction substantially perpendicular to the anchor portion and contracted in a direction substantially parallel to the anchor portion and a second form in which the body is contracted in a direction substantially perpendicular to the anchor portion and elongated in a direction substantially parallel to the anchor portion;
the deformation portion comprising a plurality of first through holes;
a thread member adapted to maintain the deformation portion in a desired form between the first form and the second form;
a connecting portion connecting the anchor portion and the deformation portion to each other, and the anchor portion being movable relative to the connecting portion to vary an angle between the plate-shaped anchor portion and the plate shaped connecting portion;
the thread member comprising a first part passing through one of the first through holes in the deformation portion and a second part passing through another hole of the plurality of first through holes in the deformation portion;
the connecting member or the anchor portion being provided with a second through hole through which passes a third part of the thread member, the third part being positioned between the first and second parts along the extent of the thread member; and
the thread member passing through the one of the plurality of first through holes, through the second through hole, and through the another hole of plurality of first through holes in that order.

Abstract
A tissue closure includes a body, and a thread includes a knot which is slidable on the thread. The body is composed of a plate-like anchor portion, and a deformation portion having a frame-like shape which can be deformed between a first form in which the deformation portion is elongated in a direction substantially perpendicular to the anchor portion and contracted in a direction substantially parallel to the anchor portion and a second form in which the deformation portion is contracted in a direction substantially perpendicular to the anchor portion and elongated in a direction substantially parallel to the anchor portion. The tissue closure can also include a connecting portion connecting the anchor portion and the deformation portion to each other. In the condition where the deformation portion is in a desired form between the first form and the second form, the condition is maintained by the thread.
