摘要:
A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.

Systems and methods for measuring turbulent gas flux using high-speed vertical wind speed measurements (e.g., on the order of 5-10 Hz or more frequently) and low-speed gas content measurements (e.g., on the order of 5 Hz or less frequently), without the need for the sophisticated and expensive high-speed hardware to separate gas samples (e.g., into accumulation bags) according to updrafts and downdrafts. A time series of high-speed vertical wind speed data is used as a guide to distinguish between updrafts and downdrafts. When vertical wind speed is upward (updraft), the low-speed gas content is recorded into a data structure in one location, or marked with one flag. When vertical wind speed is downward (downdraft), the low-speed gas content is recorded into a different location, or marked with a different flag. Eddy Accumulation or Relaxed Eddy Accumulation computations can be performed using the stored gas content data to determine gas flux.

Elongate medical devices such as guidewires can be formed from a core wire and a preformed distal cap that is configured to fit over a distal end of the core wire. The distal cap can be attached using a variety of techniques. In particular, the distal cap can be attached to the core wire using laser welding.

Alternative designs, materials and manufacturing methods for medical devices. Some embodiments relate to a medical device including two or more components or structures that are connected through heat crimping. In some embodiments, the heat crimping involves the use of a heat source to heat the material of one of the structures being connected to a point where it can flow or deform onto a surface of the other of the structures, and can thereafter be allowed to cool and form a mechanical bond between the two structures. In some embodiments, LASER energy is used as the heat source. Several alternative guidewire tip constructions and/or designs including methods and techniques of construction are also disclosed.

An embodiment is directed to a method for limiting network communications. The method is implemented at a device through which communications can be routed between client devices and the internet. The method includes receiving a routable communication. A communication type for the routable communication is identified. The communication type may be owner, authorized, or anonymous. Access rules for the identified communication type are identified. The routing of the communication is limited according to the identified access rules.

A computer readable medium comprises executable instructions to: provide an SDK to a client computer comprising executable instructions for communicating with a build server, receive an HTML/Javascript source application and a configuration file referencing one or more source application files over a computer network from a client computer to the build server, transmit the HTML/Javascript source application and configuration file to multiple compile servers corresponding to each of multiple mobile device platforms, combine the HTML/Javascript source application with a mobile device platform specific framework source code for each mobile device platform on each compile server, compile the HTML/Javascript source application and framework source code on the compile server to output an executable native application for each mobile device platform, and transmit each executable native application from the compile server to the client computer over a computer network.
摘要:
A system for communicating with a microprocessor includes an interface agent that facilitates a communications link between customized windows applications and a suite of development tools. The system allows for interactive hardware and software verification testing of a microcontroller or microprocessor contained within any type of platform, such as mass produced electronic subassembly, consumer product, or a demonstration board. The system also allows for interactive tutorials about the suite of development tools and capabilities of a selected microcontroller or microprocessor. The interface agent affords a high level of interactivity during the tutorials, which involves requesting the user to perform tasks and monitoring for execution of the tasks.

An embodiment is directed to a method for selectively routing a DNS request in which a DNS request to translate a domain name is received from a local client device. The DNS request is directed to a remote DNS server on a remote network. A link status to the remote network is identified. If the link status indicates that a connection to the remote network is not possible, the DNS request is routed to a locally embedded DNS server. If the link status indicates that a connection to the remote network is possible, the DNS request is routed to the remote DNS server on the remote network.
