Patients having diminished circulation in the cerebral vasculature as a result of stroke or from other causes such as cardiac arrest, shock or head trauma, or aneurysm surgery or aortic surgery, are treated by flowing an oxygenated medium through an arterial access site into the cerebral vasculature and collecting the medium through an access site in the venous site of the cerebral vasculature. Usually, the cold oxygenated medium will comprise autologous blood, and the blood will be recirculated for a time sufficient to permit treatment of the underlying cause of diminished circulation. In addition to oxygenation, the recirculating blood will also be cooled to hypothermically treat and preserve brain tissue. Isolation and cooling of cerebral vasculature in patients undergoing aortic and other procedures is achieved by internally occluding at least the right common carotid artery above the aortic arch. Blood or other oxygenated medium is perfused through the occluded common carotid artery(ies) and into the arterial cerebral vasculature. Usually, oxygen depleted blood or other medium leaving the cerebral vasculature is collected, oxygenated, and cooled in an extracorporeal circuit so that it may be returned to the patient. Occlusion of the carotid artery(ies) is preferably accomplished using expansible occluders, such as balloon-tipped cannula, catheters, or similar access devices. Access to the occlusion site(s) may be open surgical, percutaneous, or intravascular.

An improved method and system for identifying individual users accessing a web site. A web site server is able to identify distinct users by using a unique identifier associated with each client computer system requesting access to the web site. The unique identifier comprises an Internet address, such as an Internet Protocol (IP) address, and a time value associated with each client computer system requesting access to the web site. On starting up a web browser, an application program or browser plug-in may synchronize the internal clock included with the client computer system with a global time standard. The synchronized time value may be based on an event associated with the client computer system, such as the start of a web browser. A web site server may determine the uniqueness of the client computer system by comparing unique identifier records of users accessing the web site. A user may be identified as distinct if no matching record exists in the database. Multiple client computer systems having a common Internet address may be identified by using this method. Users privacy is also protected as the unique identifiers are erased when the client computer system's user exits the web browser or powers down the computer.

The invention also provides a cached ahead concept whereby users are allowed to experience a smooth and no wait travel in the virtual world when travelling between web sites.

An expandable introducer sheath can actively be induced to reduce in diameter or enlarge in diameter due to a braided internal structure that has axial strands connected to its distal end. The introducer sheath is delivered to the blood vessel or other tubular member of the body in a smaller diameter configuration with the axial strands in compression. The catheter is flexible and can be delivered to eccentrically shaped and tortuous vessels. Once the catheter is in position, the axial strands are placed into tension to cause the introducer sheath to assume a larger diameter configuration that will help straighten out tortuous vessels. The access site into the blood vessel is expanded via a radial expansion that is less traumatic. Passage of a larger interventional catheter can proceed through the larger diameter sheath configuration. If the interventional catheter has a smaller shaft, the introducer sheath can be reduced in diameter to come into close approximation with the shaft to reduce the opening size at the access site. The sheath can be removed over time with incremental reductions in its diameter to allow the access site time to relax to a smaller size for improved vascular sealing.

A sheath introducer is inserted through the skin and into a body lumen, e.g., the femoral artery, for a medical procedure. Upon completion of the medical procedure, the sheath introducer is partially withdrawn from the body lumen so that at least one through-wall hole in a body region of the sheath introducer is positioned outside the body lumen, but under the skin. An opening in a distal end tip of the sheath introducer is sealed so that no blood is flowing into the sheath introducer the after sheath introducer is partially withdrawn. A surgical sealant is injected into the sheath introducer and flows out of the at least one through-wall hole and surrounds the access site. After injection of the surgical sealant, the sheath introducer is removed. The surgical sealant seals the puncture and minimizes any blood flow from the body lumen through the puncture.
