摘要:
A integral vascular filter system comprising a guidewire and an integral filter which can be used to capture embolic particulates during medical procedures, while allowing for continuous perfusion of blood, with minimal incremental blood flow turbulence. The vascular filter system addresses the clinical problem of minimizing profile or diameter, so as to enable or facilitate the crossing of a lesion or obstruction in the vessel, while also minimizing incremental blood flow turbulence which may result in thrombus formation.

In accordance with the present invention there is provided a delivery apparatus for a self-expanding stent. The apparatus includes an outer sheath, which is an elongated tubular member having distal and proximal ends. The outer sheath is made from an outer polymeric layer, an inner polymeric layer, and a braided reinforcing layer between the inner and outer layers. The reinforcing layer is more rigid than the inner and outer layers. The apparatus further includes an inner shaft located coaxially within the outer sheath. The shaft has a distal end, extending distal to the distal end of the sheath, and a proximal end, extending proximal to the proximal end of the sheath. The shaft further includes a stop attached thereto. The stop is proximal to the distal end of the sheath. Lastly, the apparatus includes a self-expanding stent located within the sheath. The stent makes frictional contact with the inner layer of the sheath. The stent is located between the stop and the distal end of the sheath, with a portion of the shaft disposed coaxially within a lumen of the stent. The stent makes contact with the stop during deployment of the stent.

Content servers are directed to send messages to network nodes which are used to obtain IP addresses and to receive responses from the network nodes. The responses provide network service information. The content servers collect data based on the responses and feed the data to a routing server. Based on the data fed to the routing server, respective choices of content servers are selected and provided to the network nodes to respond to clients requesting content server addresses from the network nodes.

The invention provides specific transgenic rice plants, plant material and seeds, characterized in that these products harbor a specific transformation event at a specific location in the rice genome. Tools are also provided which allow rapid and unequivocal identification of the event in biological samples.

Server selection is optimized using randomness, feedback, and fanout. A central server maintains a vector of server selection probabilities and provides a subset of candidate servers from the vector for the client in response to receiving from a client a request for a server address to provide substantive service. An interrogating node (i.e., the client or DNS proxy) probes the candidate servers and selects a best server based on at least one criterion. The client accesses the selected server for the substantive data, and the selected server updates a counter used to keep track of the number of times the server is selected. The servers feedback the number of times selected to the central server, which, in turn, updates weightings in the vector of server selection probabilities.

Methods and apparatuses of registering on a camera display separate fields of view of a visible light camera module and an infrared camera module by focusing the IR camera module. The fields of view can be displayed in several display modes including 1) full screen visible, infrared and/or blended, 2) picture-in-a-picture such as partial infrared image in a full screen visible image, and 3) infrared color alarms in visible-light images.

A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic The filter further includes a hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism member that is constructed from a porous material and is situated such that gas entering the filter assembly passes through at least a portion the hydrophilic member. In a further embodiment, the filter includes a hydrophobic member positioned downstream of the hydrophilic member. The hydrophobic member acts as a second line of defense against moisture reaching the sensing mechanism in the gas sampling assembly.
摘要:
A system and method for vacuum bag assembly fabrication via the vacuum bag method which reduces the amount of trapped air. The inventive system includes a chamber adapted to contain a vacuum bag and first and second evacuating mechanisms. The first evacuating mechanism serves to evacuate the bag and vent to atmosphere. The second evacuating mechanism serves to evacuate and vent the chamber to atmosphere. Thus, generally, the inventive method includes the steps of placing a vacuum bag lay up in an air tight chamber; and evacuating the vacuum bag lay up and the air tight chamber at the same time. In practice, the assembly would consist of at least two components and a heat curable composition. The components can be parts to be bonded together or layers of cloth to be made into a laminate. In this case, the heat curable composition would be a catalyzed adhesive or resin.

An embolic coil detachment system includes an elongated, flexible shape memory polymer tube having an inner wall surface defining an interior lumen. A distal portion of the shape memory polymer tube has an enlarged and reduced diameter configurations. An embolic coil is releasably mounted to the shape memory polymer tube by a headpiece releasably attached within a distal portion of the shape memory polymer tube. A resistive heating element disposed longitudinally along and in immediate contact with the inner wall surface of the distal tubular wall of the shape memory polymer tube provides direct, even heating to release the headpiece and embolic coil attached thereto when the resistive heating element is energized.
