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 rail assembly includes an outer rail, a middle rail, an inner rail, and a retrieving unit. The outer rail has an outer rail space for accommodating the middle rail, the inner rail, and the retrieving unit. The middle rail slides in the outer rail space and has a middle rail space for accommodating the inner rail. The inner rail is accommodated in the middle rail and slides in the middle rail space. The retrieving unit is assembled on one end of the outer rail space.
