Abstract: Disclosed delivery catheters have a three-dimensional curvature that facilitates reaching the RAA from the inferior vena cava, positioning the distal end of the catheter generally parallel to the plane of the pericardial space at the puncture location within the RAA, orienting the puncturing device in a direction that avoids the right coronary artery, aorta, pulmonary artery, and other structures to prevent bystander injury to such structures, and provides sufficient rigidity to puncture through a wall of the RAA into the pericardial space.

Abstract: A method of performing angioplasty includes accessing an artery, inserting a tubular balloon into to the artery in a low-profile operating mode, the tubular balloon constrained in a generally helical shape, and forming a lumen within the generally helical shape by expanding the tubular balloon into a high-profile operating mode. A system for creating a lumen is also disclosed.

Abstract: Non-invasive sensor apparatus and method for assessing cardiac performance. A wide variety of different sensor components can capture sensor readings relating to patient attributes. Those sensor readings can then be compared by a processor component to derive a cardiac performance indicator relating to the patient.

Abstract: Systems, methods, and other embodiments associated with providing efficient management of records of information associated with a computer application are described. In one embodiment, a record management tool is disclosed that dynamically generates workgroups of related records and allows easy and efficient navigation between the records in a workgroup via secondary navigation buttons provided as part of a graphical user interface. In response to user navigation between the records of a workgroup, a displayed editor is switched in a common editor space provided by the graphical user interface. The displayed editor corresponds to a presently selected secondary navigation button and associated record. Navigating between records and switching between editors may be accomplished without having to close any records of the workgroup.

Abstract: A catheter assembly for sensing the temperature of an arterial wall or other body lumen includes a blood-flow-occluding feature to increase the accuracy the temperature measurements. In addition to the flow-occluding feature, the catheter includes a distal end with a temperature sensing structure and a proximal end including a manually operated expansion control. The temperature sensing structure includes one or more presentation elements in the form of a basket or braided structure having at least one temperature sensor supported thereon, each sensor being operative to generate an electrical signal indicative of temperature. In the preferred embodiment, the feature to occlude blood flow is an inflatable balloon disposed near the expandable basket or braid structure. The temperature sensors are preferably thermistors, and an elastic sleeve covering the expandable basket or braid structure is also preferably provided to further insulate the temperature sensors from the cooling effects of blood flow.

Abstract: The present invention relates to atom probe data and associated systems and methods. Aspects of the invention are directed toward a computing system configured to predict a characteristic associated with an atom probe specimen that includes a data set receiving component configured to receive a three-dimensional data set associated with a portion of the specimen. The system further includes a predicting/calculating component configured to predict the characteristic associated with the specimen based on the data set. Other aspects of the invention are directed toward a method for evaluating a manufacturing process using atom probe data that includes receiving a three-dimensional data set associated with a portion of a microelectronic assembly produced by a manufacturing process. The method further includes determining a variation between the data set and a configuration expected to result from the manufacturing process.

Abstract: Embodiments are an improved transistor structure and the method of fabricating the structure. In particular, a wet etch of an embodiment forms source and drain regions with an improved tip shape to improve the performance of the transistor by improving control of short channel effects, increasing the saturation current, improving control of the metallurgical gate length, increasing carrier mobility, and decreasing contact resistance at the interface between the source and drain and the silicide.

Abstract: A datagram network is operated by placing a group address in the source address field of the datagram. Nodes within the datagram network forward the datagram in dependence on the contents of the source address field. This provides many of the scalability advantages offered by Multiprotocol Label Switched (MPLS) networks without introducing the overheads caused by connection set-up in MPLS networks. The method can also easily provide different quality of service levels to different types of packets and is especially useful in providing Virtual Private Networks across a shared internetwork such as the public Internet.
