  • Publication number: 20200197009
    Abstract: An anastomosis assist tool comprises a body unit extending in a predetermined advancing direction, and an insertion unit arranged at the tip of the body unit. The body unit includes an anastomosis assist part having an approximately constant cross-sectional shape in a plane perpendicular to the advancing direction. The anastomosis assist part includes a projection projecting outwardly as viewed in the cross section and extending in the advancing direction. The insertion unit includes a tapered part of a diameter decreasing gradually toward a tip. When the insertion unit and a part of the body unit are inserted into a vessel, the projection of the anastomosis assist part of the body unit abuts on the inner wall of the vessel. This makes it unlikely that the inner wall of the vessel will stick to the body unit at a site other than a point abutting on the projection.

  • Publication number: 20190191692
    Abstract: For perfusion, blood vessels protruding from a removed organ or tissue and cannulas for circulating perfusate are tightened and bound at positions away from the cut ends of the blood vessels toward a proximal side viewed from the organ. The cut ends of the aforementioned blood vessels that are anastomosed to blood vessels of a living body are spaced from the binding positions at which the cannulas are secured. The direction to the blood vessels of the living body can be conducted while moving the cannulas in various postures relative to the blood vessels protruding from the organ or tissue. This enables performing an anastomosis operation while maintaining the perfusion state. In this way, organs and tissues that include at least one artery route and at least one vein route can be anastomosed to blood vessels of a living body while maintaining the perfusion state.

  • Publication number: 20190141988
    Abstract: A perfusion device and a perfusion method can allocate two routes of perfusate inflow pathways and two routes of perfusate outflow pathways for a liver graft. The perfusate inflow pathways have perfusate inflow cannulas connected respectively to the portal vein and the hepatic artery. The perfusate outflow pathways have perfusate outflow cannulas connected respectively to the suprahepatic inferior vena cava and the infrahepatic inferior vena cava. Perfusate is allowed to enter the liver from the perfusate inflow cannulas, and the perfusate in the liver is allowed to drain off from the perfusate outflow cannulas. This significantly shortens the time length of the liver graft being in an ischemic condition when the liver is removed or transplanted. That is, the onset of disorder in the liver graft can be suppressed. This increases the success rate of liver transplantation. Thus, deterioration of organ grafts during surgery is prevented in organ transplantation surgery that requires long hours.
