Surgical systems for less invasive access to and isolation of an atrial appendage are provided. A suturing grasper compresses soft tissue structures and deploys one or more sutures through complimentary pledget(s) carried by the grasper. The pledgets are reinforced, containing support members that define the profile of the stitch and distribute stresses applied by the stitch, once tightened, over a length of tissue. This hardware may be applicable to other surgical and catheter based applications as well including: compressing soft tissue structures lung resections and volume reductions; gastric procedures associated with reduction in volume, aneurysm repair, vessel ligation, or other procedure involving isolation of, resection of, and reduction of anatomic structures.

An electrochemical sensor system and membrane and method thereof for increased accuracy and effective life of electrochemical and enzyme sensors.

A method, system, and program for managing failover of J2EE compliant middleware in a high availability system are provided. A primary node and a secondary node each run the same J2EE compliant middleware stack comprising layers including a load balancer, a web server, a web application server, a message control server, a monitoring server, and a database control server. In the primary node, all layers are active. In the secondary node, part of the layers are active and part of the layers are in standby. A data replication partition shared between the primary node and the secondary node includes persistent resource data accessible to a selection of the layers of the primary node. A heartbeat controller monitors each node, including the middleware stack, and upon detection of a failure, controls transfer of the services provided by the primary node to the secondary node by transferring virtual IP addresses from the primary node to the secondary node, remounting the data replication partition for access by the secondary node, and activating the standby layers which require access to the data in the data replication partition.

The invention discloses a medium thick heavy-pitch crushed ore body frame type artificial top downward segmenting cemented filling method which comprises the following steps: dividing chamber jambs along the trend of an ore body; adopting a rail-less mining aligning system; pre-constructing a high-strength reinforced concrete artificial top in a segmented drilling lane; adopting a stoping sequence from up to down; performing drilling and blasting ore removal on the ore body through the segmented drilling lane at bottom; adopting medium-length hole drilling and remotely controlling a scraper to discharge ore; after finishing the mining of the chamber, utilizing concrete tailings to perform cemented filling; after finishing the mining of the jambs, utilizing concrete tailings or pure tailings to perform cemented filling; after completely stoping the mine chamber in the frame under the protection of the concrete artificial top, starting to stope the jamb adjacent to the segment, and meanwhile stoping the corresponding mine chamber in the frame of the next segment, and then stoping the corresponding jamb of the next segment; and after completely mining the chamber jamb in the middle segment, immediately turning towards the lower middle segment for stoping. The method provided by the invention has the advantages that the safety for mining the heavy-pitch medium thick crushed or ultra-crushed ore body is high, the resource depletion loss rate is low, the mechanical degree is high, the production capacity is high, and the like.

A blood vessel occlusion system and method includes a handheld probe including a power source, the probe being adapted to transmit energy from the power source through a body surface and into a target blood vessel, for example a varicose vein. Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel. When the blood vessel is compressed sufficiently to collapse and substantially slow or substantially prevent a flow of blood therethrough, the power source is activated and the vessel is cauterized, leaving the blood vessel in a condition that is resistant to recanalization.

A retractor for use in surgical operations comprises a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis. The retractor further comprises a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In operation, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, thereby stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision.) The retractor thus forms an aperture for passage of surgical instruments and viewing of the surgical field by surgical personnel. In some embodiments, the retractor features a pair of removable handles that may be removed from the arms during surgery in order to afford the surgeon improved space management about the incision. In specific embodiments, the invention provides a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor.

The invention relates to a method for protecting crossed Ethernet network, wherein said network is arranged with quick annular network protective region; said region comprises a main ring and a sub ring; main ring is the virtual main node of sub ring; the main ring via the first and second edge nodes is crossed with sub ring; the port of first edge node connected to the sub ring is the first port of virtual main node; the port of second edge node connected to the sub ring is the second port of virtual main node. And said method comprises following steps: setting the second port of virtual main node as transfer mode; the first port of virtual main node is block mode; checking if the sub ring has chain accidence; if it is, setting the first port of virtual main node as transfer mode, and initializing the refresh transfer list information; when the accidence of sub ring is recovered, setting the first port of virtual main node as block mode, to initialize the refresh transfer list.
