Abstract: The present invention features an all-in-one system for vascular access and closure. In particular, this invention features systems and methods for forming holes in blood vessels and rapidly closing these vessel holes using an all-in-one system. For example, an arterial access and closure port system is disclosed herein to provide fail-safe percutaneous entry and exit into any artery, particularly useful for high flow and high pressure arteries such as the carotid artery. The present invention is a single system that forms and closes vascular holes and can be used for percutaneous arterial access with interventional radiology, interventional cardiology, neuro-intervention, endovascular surgery, and endovascular neurosurgery.

Abstract: A wall construction includes two mold boards spaced from each other for forming a chamber between the mold boards, a connection rod disposed between the mold boards, two connecting members attached to the connection rod and engaged through the mold boards and engaged with the mold boards for positioning the mold boards in place relative to each other, and two bracing members attached to the outer ends of the connecting members and engaged with the mold boards for further positioning the mold boards in place relative to each other, two frame members are engaged with the mold boards and secured to the mold boards with lock members.

Abstract: An auto-returning track device comprises a retaining track; a lower side of the retaining track having a protrusion; the retaining track having a sliding space enclosed by two stops at two ends and a retaining seat; a movable track received in the sliding space and slideable with respect to the retaining track; the movable track having a hook with respect to the retaining seat; a movable base received in the sliding space and between the movable track and the retaining seat; at least one returning element being installed between the movable base and the retaining seat; and a positioning buckle swingably pivoted with the movable base; an outer surface of the positioning buckle being formed with a positioning groove for hooking with a hook of the movable track; a hook portion extending from a lower surface of the movable track; the hook portion can be hooked to the protrusion.
