Abstract: Anastomotic methods and devices for placing a target vessel in fluid communication with a target vessel. A conduit (10) includes an attachment portion (12) adapted to be secured to a target vessel in fluid communication with the lumen of the vessel. The target vessel wall is sandwiched between first and second components (14, 16) of the attachment portion (12) to provide both a secure and sealed connection. One component (14) is placed in the vessel lumen against the interior surface of the wall and has an outlet that directs blood into the target vessel. This component (14) is elongated, e.g., elliptical or rectangular, such that a minimum amount of material is present at the outlet. This results in the outlet having a diameter that substantially maintains much of the cross-sectional area of the native target vessel. The attachment portion does not significantly occlude the target vessel lumen, is secured to the vessel wall in non-penetrating fashion.

Title: Method and apparatus for transmission of node link status messages
Inventor: LI CHRIS CHO-PIN
IPC: H04L12/56
Filed: 2000-11-09
Abstract: The present invention transmits Link-State Advertisement (LSA) type or database update messages or packets of an internetworking protocol within a wireless communication system or network via insertion of the packet within packets of an intranet protocol. The wireless network includes a plurality o f nodes arranged into clusters having cluster member nodes and a designated cluster head node. The nodes communicate with each other via an intranet protocol, while the network may communicate with other external networks in accordance with an internetworking protocol (e.g., a Radio Open Shortest Pat h First (ROSPF) protocol). A database within each network node contains link information for that node, while the ROSPF LSA type packets contain information to update the node databases. The ROSPF LSA type packets are transmitted to neighbors of each node to enable each database to maintain current information. In order to reduce overhead of transmitting numerous LS A type packets, the present invention transmits the ROSPF LSA type packet with in an intranet protocol beacon type or node status packet that is periodically broadcasted within the network.
