  • Publication number: 20110130820
    Abstract: Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.

  • Patent number: 7653765
    Abstract: An apparatus and method for communicating information within a network having one or more communication buses (5, 6, 7, 8), consisting of one or more elements (20, 30, 40) to maximise throughput and minimise CPU involvement by executing the following. Compare incoming message identifiers (14) against a set of predetermined identifiers (22). Transpose data sets (12) within the incoming message data frame and where necessary, save and/or transmit new frames as defined by operations dependent upon the incoming identifier. By utilising an optimal set of operands the memory requirement is satisfied by a minimal size of standard type.

  • Publication number: 20080109055
    Abstract: Methods and devices for treating an aortic dissection having an entry point downstream of the takeoff of the left subclavian artery. The devices include a catheter that carries an endoluminal implant at a distal region of the catheter. The implant is a self-expanding tubular mesh or strutted stent. A capture sheath holds the stent in a compressed state for percutaneous delivery. The catheter is advanced to position the stent adjacent the entry point of the dissection. The stent is released by withdrawing the capture sheath. The stent expands to engage the intimal lining and press the intima into contact with the outer layers of the aorta and thereby promote healing of the dissection.

  • Patent number: 7157312
    Abstract: A surface mount package for a multi-chip device has a leadframe formed with first and second die pads and readouts from the respective die pads. An environmentally responsive sensor chip is secured to the first die pad and an environmentally isolated chip is secured to the second die pad. The chips are electrically coupled through the lead frame. A body formed with an over molded portion encases the isolated chip and an open molded portion formed with a recess receives the environmentally sensitive chip. An apertured cover is secured in the recess to form a protective covering over the sensor chip and for allowing communication of the sensor chip externally of the package.

  • Publication number: 20060274755
    Abstract: An apparatus and process for relabelling and redirecting at least some of the read transaction data frames and the write transaction write data and transfer ready frames in a network so as to bypass a storage manager and pass directly between the client and a storage device via a switch. This eliminates the storage manager as a bottleneck. Some embodiments redirect every read and write transaction, and others redirect only large transactions, or only ones not stored in cache or when latency gets too high. Redirection is accomplished by transmission from the storage manager to a switch redirection commands that contain old and new address data. When a frame to be redirected comes in, its address is compared to the old address data. If there is a match, the new address data is substituted and the frame is passed to a conventional routing process to be routed so as to bypass the storage manager.

  • Publication number: 20060107337
    Abstract: Porcine nucleic acid sequences flanking potentially infectious porcine endogenous retroviral (PERV) insertion sites have been identified and isolated. The unique flanking sequences include porcine nucleic acid sequences that flank the 3? end and porcine nucleic acid sequences that flank the 5? end of PERV insertion sites. The present invention provides compositions and methods for detecting presence of PERV in a sample, particularly those with infectious potential. In addition, the invention relates to breeding of pigs or selection of porcine tissue that is free of infectious PERV for use as a xenotransplant tissue.

  • Publication number: 20040267290
    Abstract: Methods and apparatus for making an anastomotic connection between an opening at an end of a graft conduit and an aperture in a side wall of a body tissue conduit using a hollow connector assembly are provided, wherein the cross-sectional area of the anastomotic connection is larger than that of the graft conduit. The tissue about the opening is introduced about and retained by first members of a distal portion of the connector assembly held by a loading tool. A delivery tool then collapses a proximal portion defined by second members of the connector assembly and delivers the second members into the lumen of the body tissue conduit via the aperture. Upon inserting the second members into the body tissue conduit, the delivery tool is disemployed and the second members expand such that they press against the interior wall of the body tissue conduit and such that the first members are held within the aperture against a medial wall of the body tissue conduit.
