An endoprosthesis expansion system having, in combination, a delivery component such as a length of catheter tubing having at its distal end an intermediate sheath component, and an inner tube within the full length of the delivery catheter and intermediate sheath component. The inner tube has a protrusion affixed to its distal end, and an expandable endoprosthesis is fitted in a compacted state about the intermediate sheath, immediately proximal to the protrusion. If the endoprosthesis is a self-expanding endoprosthesis (as is preferred), an exterior constraining sheath is required around the outer surface of the endoprosthesis. Following insertion of the endoprosthesis and delivery system into a body conduit (such as a blood vessel) and transport of the endoprosthesis to the desired site within the body conduit, the endoprosthesis is deployed by axially moving the protrusion against the system, thereby applying a radially directed outward force and causing simultaneous dilatation of the intermediate sheath and disruption of the exterior constraining sheath. Disruption of the exterior constraining sheath, in the case of a self-expanding prosthesis, releases the stored energy in the formerly constrained prosthesis, allowing it to expand and accomplish full deployment against the luminal surface of the body conduit at the desired site.

The present invention is directed to a deployment system for a self-expanding endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device so that upon deployment the sheath is transitioned into an internal deployment line housed within the catheter. The deployment system is configured to prevent rotation of the catheter relative to the deployment line during deployment line actuation.

Large diameter self-expanding endoprosthetic devices, such as stents and stent grafts for delivery to large diameter vessels, such as the aorta, are disclosed having very small compacted delivery dimensions. Devices with deployed dimensions of 26 to 40 mm or more are disclosed that are compacted to extremely small dimensions of 5 mm or less, enabling percutaneous delivery of said devices without the need for surgical intervention. Compaction efficiencies are achieved by combining unique material combinations with new forms of restraining devices, compaction techniques, and delivery techniques. These inventive devices permit consistent percutaneous delivery of large vessel treatment devices. Additionally, small endoprosthetic devices are disclosed that can be compacted to extremely small dimensions for delivery through catheter tubes of less than 1 mm diameter.

A computer arrangement for providing services to clients over a network includes: at least two servers, each server hosting at least one application, an automated administrator configured to automatically provision the servers to provide the services, and at least one network load balancer connected to the clients and the servers. The network load balancer is responsible for at least one of the services and is configured to gather state information on the state of the servers and/or the applications hosted on the servers and is operable to route incoming requests of clients to at least one of the servers. The network load balancer provides the automated administrator with the state information. The automated administrator provides the network load balancer with provisioning information regarding which servers are provisioned to provide the at least one service for which the network load balancer is responsible.
摘要:
A broad band surface profiling apparatus including a reference calibrator for calibrating the apparatus to compensate for surface features of the reference surface. A user is instructed to conduct calibration measurement operations using a calibration sample having a calibration surface to obtain calibration surface topography data for the calibration sample. At each calibration measurement operation, an image representing the calibration surface topography data is displayed to the user and the user has the option to accept or reject the calibration surface topography data represented by the displayed image. The reference calibrator has a surface topography data processor and a mean surface calculator for calculating mean surface topography data using the processed calibration surface topography data accepted by the user to provide reference surface features data. A reference surface features remover is provided for adjusting surface topography data obtained for a sample surface in accordance with the reference surface features data.
摘要:
The aspects of the present invention provide a computer implemented method, an apparatus, and a computer usable program code for identifying a service processor with current setting information. First stored information for a service processor is retrieved from a first memory in the first service processor. Second stored information for the service processor is retrieved from a second memory in a data processing system to which the service processor is connected. The first stored information is compared with the second stored information to form a comparison as to whether the service processor was previously connected to the data processing system and to determine whether the service processor was a last service processor to fully communicate with system firmware in the data processing system. The service processor has current setting information if the service processor was previously connected to the data processing system and was the last service processor to fully communicate with the system firmware.

摘要:
The present invention relates to the design and manufacture of single cell units for planar, thin-film, ceramic electrochemical devices such as solid oxide fuel cells, electrochemical oxygen generators, gas separation membranes, and membrane modules and stacks and the fabrication of multi-cell stacks and modules of the single cell units. The design is based upon a single cell wherein manufacturing all layers of the device into an integral unit produces a monolithic structure. The design produces a gas-tight single cell that is easily assembled into multi-cell stacks and modules without external seals or sealing mechanisms. The design may use standard ceramic and metallurgical production techniques. The design of the present invention enhances device performance since the single cell units are inherently sealed for gas tightness and have reduced interfacial electrical resistances. All these features of the novel monolithically integrated unit cell design result in lower manufacturing costs for ceramic electrochemical devices.
