Zusammenfassung:To provide a blood vessel access closure device capable of determining if the hole has been adequately closed, or whether the hole is still leaking blood.SOLUTION: A blood vessel access closure device includes an inner blood vessel wall support member 102 and an outer blood vessel wall support member 104. The closure device also includes a deployment member 106 and an electrode 120. The deployment member is configured to draw the inner and outer blood vessel wall support members towards each other when the inner and outer blood vessel wall support members are deployed on opposite sides of a blood vessel wall during closure of a hole 96 in the blood vessel wall. The electrode is configured to be attached to the deployment member and configured to be used to measure impedance.SELECTED DRAWING: Figure 1 【課題】孔が十分に閉じられたか否か、或いは、孔からまだ血液が漏れているか否かを判定することができる血管アクセスクロージャーデバイスを提供する。【解決手段】血管アクセスクロージャーデバイスは、内側血管壁支持部材102と外側血管壁支持部材104とを含む。クロージャーデバイスは更に、配置部材106と電極120とを含む。配置部材は、血管壁の孔96を塞ぐ際に内側血管壁支持部材及び外側血管壁支持部材が血管壁の両側に配置される場合に、内側血管壁支持部材及び外側血管壁支持部材を互いに向かって引き寄せるように構成されている。電極は、配置部材に取り付けられて、インピーダンスの測定に使用されるように構成されている。【選択図】図1
