Abstract

A living body tissue closing device 1 includes an elongated body element 2, a clip (living body tissue closure) 4 for closing a wound hole which penetrates a living body tissue membrane, and a thread 8. The body element 2 includes a sheath 5, and elongated feeding and deformation means 3. The elongated feeding and deformation means 3 includes a covered tube 6, a pusher tube 7, a thread anchoring cap 9, a guide wire 11, and a stopper 12. The clip 4 includes a seal portion 41 for covering the wound hole and a peripheral portion of the wound hole from one side of the living body tissue membrane, a deformation portion 42 deformable between a first form in which the deformation portion 42 can pass through the wound hole and a second form in which the deformation portion 42 can cooperate with the seal portion 41 to sandwich the living body tissue membrane therebetween from the other side, and a fastener portion 43 for retaining the deformation portion 42 in the second form.

Description

[0001] This application is an international application that entered the Chinese national phase with the filing date of December 24, 2004, the international application number: PCT / JP2004 / 019734, the national application number: 200480035604.4, and the name "tissue closure device and tissue closure device" divisional application. technical field [0002] The present invention relates to tissue closure devices and tissue closure devices for living organisms. In particular, the present invention relates to biopsy closers and biopsy closure devices. Background technique [0003] Minimally invasive procedures performed by inserting devices for diagnosis and treatment, such as catheters, into blood vessels or some other living tissue are generally performed widely. For example, in the treatment of heart coronary artery stenosis, it is necessary to insert a device such as a catheter into the blood vessel in order to treat the stenosis. [0004] Such insertion of a catheter into ...
