Means and method of replacing a heart valve in a minimally invasive manner
A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners and is self-contained whereby a fastener is delivered and placed all from inside a vessel. The fasteners are self-forming whereby they do not need an anvil to be formed. Anchor elements are operated from outside the patient's body to cinch a prosthesis to an anchoring cuff of the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. Fasteners are placed and formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner. Fasteners that are permanently deformed during the process of attaching the cuff are disclosed as are fasteners that are not permanently deformed during the attaching process.

Stable coil designs
This is an implantable vaso-occlusive device. The device has a complex, three-dimensional structure in a relaxed configuration that may be used in the approximate shape of an anatomical cavity. It may be deployed in the approximate shape of a sphere, an ovoid, a clover, a box-like structure or other distorted spherical shape. The loops forming the relaxed configuration may pass through the interior of the structure. The device is a self-forming shape made from a pre-formed linear vaso-occlusion member. Fibers may be introduced onto the device and affixed to the pre-formed linear member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vaso-occlusive device into appropriately shaped forms and annealing them to form various devices.

ActiveUS7194002B2Improve balanceSlowed network performanceSpecial service provision for substationDigital computer detailsSelf formingGroup method
A network performance (e.g., latency and bandwidth) measurement infrastructure for large scale networks based on self-organized probing groups of devices. Each group of devices has a lead device that measures network characteristics, and then shares the measurement information with other devices. This grouping method reduces the amount of network bandwidth needed for adequate measurements, while still providing necessary information to individual devices. The system utilizes a novel multicast-based algorithm that is adopted for both intra-group and inter-group performance measurement. The measurement groups (MeGroups) are dynamic and self-forming, and use a set of heuristic algorithms to optimize the dynamic groupings.

ActiveUS8169936B2Multiplex system selection arrangementsSpecial service provision for substationSelf formingConference call
Methods for inter-mixer communication enable a “self-formed” cascaded mixer node tree topology. One method enables inter-mixer node signaling and includes first selecting a plurality of media flow payloads at a first cascaded mixer node. A set of conference payloads are generated and each include the media flow payloads from the plurality of media flow payloads that are part of the same conference call, an identifier for the conference call, and a node identifier for each media flow in the conference call. For each media flow in the conference call, each conference payload further identifies whether the first cascaded mixer node is a root node or a leaf node. The set of conference payloads are bundled into a single packet and sent to a second cascaded mixer node. Another method enables the “self-forming” of the mixer node tree topology. Yet another method enables active talker identification within the “self-formed” tree topology.

Electrochromic Device with Self-forming Ion transfer Layer and Lithium Fluoro-Nitride Electrolyte
ActiveUS20070292606A1Solve many processesReduce usageCoatingsSpecial surfacesEvaporationElectrochromism
A method of preparing an electrochromic device involves forming multiple layers of selected materials on a substrate in a vacuum processing chamber. A first of these layers is an electrode layer deposited directly on the substrate and used for making contact to a subsequently deposited precursor film, preferably tungsten oxide, from which an electrochromic layer is formed by lithium loading in the presence of ionized nitrogen. This not only forms the electrochromic layer by diffusion of the lithium into the tungsten oxide, but also forms a thin lithium nitride ion transfer layer on the then exposed surface. Subsequently, a lithium fluoro-nitride electrolyte layer is formed on the ion transfer layer by evaporation from a lithium fluoride source in the presence of ionized nitrogen. An ion storage layer, which may be a vanadium oxide and a transparent second electrode layer are subsequently vacuum deposited.

When a barrier film is formed on an exposed surface of an interlayer insulation film on a substrate, the interlayer insulation film having a recess formed therein, and a metal wiring to be electrically connected to a metal wiring in a lower layer is formed in the recess, a barrier film having an excellent step coverage can be formed and increase of a wiring resistance can be restrained. An oxide film on a surface of the lower copper wiring exposed to a bottom surface of the interlayer insulation film is reduced or edged so as to remove oxygen on the surface of the copper wiring. Then, by supplying an organic metal compound containing manganese and containing no oxygen, generation of manganese oxide as a self-forming barrier film is selectively allowed on an area containing oxygen, such as a sidewall of the recess and a surface of the interlayer insulation film, while generation of the manganese oxide is not allowed on the surface of the copper wiring. Thereafter, copper is embedded in the recess.

Provided are methods by which multiple devices self-form a wireless communication network and self-coordinate their access to communication media. In these methods, an individual node maintains its knowledge of other nodes in its vicinity and knowledge of those nodes' scheduled activities to an adequate degree of details. Such knowledge can be obtained by receiving control signals from nodes that are within the range of wireless communication. Examples of such knowledge include the identities of the nodes in the vicinity, the nodes' scheduled times of control message transmission and / or reception, the nodes' scheduled times of application data transmission and / or reception, etc. Such knowledge can be embodied in the form of a memory module of a computing device. The presented methods also provide a procedure by which an individual node maintains its knowledge of the scheduled signal transmission and / or reception activities, or an estimate or prediction of the scheduled transmission and / or reception activities, of other nodes that are not within the individual node's signal-reachable range.

Using this methodology, a wireless network can be self-forming or “ad-hoc” in nature. That is, the formation of the network does not depend upon the presence of a pre-determined central coordinator. Second, it can accommodate relatively rapid changes in network configuration, including changes in the number and location of the devices participating in the network, and changes in the channel conditions experienced by communication devices. Third, it can accommodate an extended network system where the population of devices that are able to communicate wirelessly, either directly, or indirectly via devices that also act as repeaters, may be spread over a relatively large geographic area. Fourth, it can provide robust Quality of Service through the use of time reservations or “slots” during which one device or a limited number of devices are allowed to transmit. Fifth, it can provide good power management qualities, such that there are mechanisms which allow devices minimize active time and to transition in and out of reduced power “sleep” states while still maintaining the ability to communication.
