    • A generally tubular stent-graft (20) includes a generally tubular support element (30) and a covering element (32) that is attached to and at least partially covers the support element (30). When the stent-graft (20) is unconstrained in a radially-expanded state, a proximal end portion (40) of the covering element (32) is shaped so as to define at least first and second proximally-extending pieces (42A, 42B). When the stent-graft (20) is unconstrained in the radially-expanded state and the proximally-extending pieces (42A, 42B) are fully proximally extended, the proximally-extending pieces (42A, 42B) (a) are shaped so as to define respective distal bases (46), which (i) have respective base lengths (L1) measured circumferentially around the stent-graft (20), and (ii) circumferentially circumscribe respective base arcs (α) of between 100 and 140 degrees, (b) are shaped so as to define respective proximal-most portions (48) more proximal than all other respective portions of the covering element (32) that circumscribe the respective base arcs (α), and (c) have respective axial lengths (L2) that equal between 50% and 150% of the respective base lengths (L1).

    • A network address associated with a packet is obtained at a search engine of a network device. The search engine includes a plurality of Bloom filters that represent prefixes of respective lengths in the routing table. Respective Bloom filters are applied to respective prefixes of the network address to determine a set of one or more prefixes for which a match potentially exists in the routing table. A number of accesses to the memory are performed using prefixes in set of prefixes, beginning with a longest prefix and continuing in decreasing order of prefix lengths until a matching entry is found in the routing table, and routing information for the packet is retrieved. If the number of performed memory accesses exceeds a threshold, the routing table is adapted to reduce a number of memory accesses to be performed for subsequent packets associated with the network address.
    • 在网络设备的搜索引擎处获得与分组相关联的网络地址。 搜索引擎包括表示路由表中相应长度的前缀的多个布隆过滤器。 相应的Bloom过滤器被应用于网络地址的相应前缀,以确定在路由表中可能存在匹配的一个或多个前缀的集合。 使用前缀集合中的前缀,以最长前缀开头并以前缀长度的递减顺序继续进行对存储器的多次访问,直到在路由表中找到匹配的条目,并且检索分组的路由信息​​。 如果执行的存储器访问次数超过阈值,则路由表适于减少对与网络地址相关联的后续分组执行的存储器访问次数。

    • An endovascular system (10) includes an endovascular implant (20) and a delivery tool (30). The implant (20) is configured to assume a radially-compressed delivery state, and a radially-expanded deployment state. The delivery tool (30) includes a proximal main delivery catheter (36), having a distal portion (46) in which the implant (20) is disposed while in the radially-compressed delivery state; and a distal restraining assembly (50), which includes a restraining-assembly tubular shaft (52) disposed distal to the proximal main delivery catheter (36). The distal restraining assembly (50) is configured to assume an engaged state, in which the distal restraining assembly (50) prevents proximal displacement of the implant (20) relative to the distal restraining assembly (50), and a disengaged state, in which the distal restraining assembly (50) allows proximal displacement of the implant (20) relative to the distal restraining assembly (50). Other embodiments are also described.
