PROBLEM TO BE SOLVED: To provide an organism tissue closure device for independently performing holding operation by press-holding means and puncture operation by a puncture part with respect to organism tissues near a defect.SOLUTION: In the organism tissue closure device, electric current is supplied to a press-holding means K while organism tissues M each composed of an interatrial septum and a valve of oval foramen are press-held by the press-holding means, and thereby the organism tissues are joined together. A hand operation part for operating the press-holding means has contact members 84 and 85 which are connected to end parts of a conductor connected to electric energy supply means and are provided at a position away from each other, and terminals 81 and 83 provided at operating members 7c for moving the puncture part and a holding member, respectively. The respective terminals 81 and 83 are brought into contact with the contact members 84 and 85 respectively as the respective operating members 7c move, and electric energy is supplied to the organism tissue M between the puncture part and the holding member by turning on a switch (SW) for performing on/off control of the supply of electric energy.COPYRIGHT: (C)2010,JPO&INPIT【課題】欠損周辺の生体組織に対する挟圧手段による保持操作と穿刺部による穿刺操作とを独立に行なうことができる生体組織閉鎖デバイスを提供する。【解決手段】心房中隔及び卵円孔弁からなる生体組織を挟圧手段により挟持した状態で、挟圧手段Kに電流を流し、生体組織を相互に融着させる生体組織閉鎖デバイスであり、挟圧手段を操作する手元操作部が、電気エネルギ供給手段と接続された導線の端部に接続され、相互に離間した位置に設けられた接触部材84,85と、穿刺部と挟持部材を移動する各操作部材,7cにそれぞれ設けられた端子81,83と、を有し、各操作部材7cの移動に伴って各端子81,83がそれぞれ接触部材84,85と接触し、かつ、電気エネルギの供給をオンオフ制御するスイッチがオンすることにより穿刺部と挟持部材との間の生体組織Mに電気エネルギを供給するようにした。【選択図】図3
