  • Laparoscopic vascular access
    Patent number: 8357190
    Abstract: A laparoscopic vascular conduit arrangement has an elongate graft tube (1, 10) which is placed through a body cavity into a body vessel using a laparoscopic port sheath (70) with a distal valve (73) and a second sheath (80) with distal valve (86, 87). The graft tube (1, 10) extends through the laparoscopic port sheath so that the distal end (108) of the graft tube extends out of its valve and the proximal end of the graft tube extends out of the proximal end of the laparoscopic port sheath. The second sheath (80) is deployed into the distal end (108) of the graft tube (1, 10) such that the first valve (73) seals around the graft tube and the second sheath (84). The proximal end of the graft tube can be deployed into the vessel of the body to allow access into the vessel through the graft tube via the second valve. The conduit can be removed after use or used to provide vascular bypass.
