In general, the invention is directed to a medical device implantable in a body of a patient. The device includes a housing with a plurality of collapsible fixation structures coupled to the housing, and can be in a collapsed configuration or an expanded configuration. The device assumes a collapsed configuration when in the bore of an insertion device, and assumes the expanded configuration when expelled from the insertion device into the body of the patient.

An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

The present invention discloses an efficient architecture for routing in a very large autonomous system where many of the layer 3 routers are attached to a common connection-oriented layer 2 subnetwork, such as an ATM network. In a preferred embodiment of the invention, a permanent topology of routers coupled to the subnetwork is connected by permanent virtual circuits. The routers can further take advantage of both intra-area and inter-area shortcuts through the layer 2 network to improve network performance. The routers pre-calculate shortcuts using information from link state packets broadcast by other routers and store the shortcuts to a given destination in a forwarding table, along with corresponding entries for a next hop along the permanent topology. The present invention allows the network to continue to operate correctly if layer 2 resource limitations preclude the setup of additional shortcuts.

A dressing for promoting healing and pain relief of the body of a living organism having a pathologic condition has at least one layer of conductive material having a resistance no greater than 1000 Ω/cm². When placed proximate a portion of the body of the living organism suffering from the pathologic condition, the dressing alters the electrodynamic processes occurring in conjunction with said pathologic condition to promote healing and pain relief in the living organism. When used as a wound dressing, the conductive material is placed in contact with tissue around the periphery of the wound and with the wound, lowering the electrical potential and resistance of the wound and increasing the wound current. In an exemplary embodiment, the conductive material is a multi-ply nylon fabric plated with silver by an autocatalytic electroless plating process and with the plies in electrical continuity. The dressing provides an antimicrobial and analgesic effect. The dressing may be provided for numerous applications and may include other layers such as an absorbent layer, a semi-permeable layer and additional layer of conductor material. Multilaminate embodiments of the present invention exhibit conductive material concentration gradients and, potentially, a capacitive effect when sequential conductor layers are insulated by intervening layers.

A computer system of the present invention is provided with an open flow controller 3, and a switch 4i. The switch 4i notifies a MAC address contained in packet data to the open flow controller 3 when the packet data from the virtual machine that the migration has completed does not fit with a rule shown by the flow set to the switch itself. The open flow controller 3 sets a communication flow for a migration destination VM generated according to the notified MAC address to the switch 4i. The switch 4i transfers the packet data for said virtual machine which follows a rule 444 shown by the communication flow for said migration destination VM, to the migration destination virtual machine based on an action 445 shown by the communication flow for said migration destination VM.

In a method of manufacturing a semiconductor device, a first wiring line composed of a copper containing metal film is formed on or above a semiconductor substrate. A first interlayer insulating film is formed on a whole surface of the semiconductor substrate to cover the first wiring line. The first interlayer insulating film is selectively removed to form a connection hole reaching the first wiring line. A barrier metal film is formed to cover an inner surface of the connection hole and then a copper containing metal film is formed to fill the connection hole. The copper containing metal film formed outside the connection hole is removed. A second interlayer insulating film is formed on a whole surface of the semiconductor substrate to cover the copper containing metal film formed in the connection hole. The second interlayer insulating film is selectively removed to form a wiring line groove such that the copper containing metal film formed in the connection hole is exposed at a bottom. A barrier metal film is formed to cover an inside of the wiring line groove and then a copper containing metal film is formed to fill the wiring line groove. Then, the copper containing metal film outside the wiring line groove is removed to form a second wiring line.
