摘要： A bi-directional system for actively deflecting the distal tip of a catheter includes a reconfigurable tube that is positioned proximal to the catheter's distal tip. The tube is formed with slits that are arranged to allow the tube to be transformed from a relaxed, cylindrical configuration to a plurality of deflected configurations. First and second pull wires are provided, with each wire having a respective distal end that is attached to the distal end of the tube. Each wire extends to a catheter handle where it is attached to a respective reel. The reels can be rotated, back and forth, to selectively deflect or relax the tube. To ensure a smooth recovery after a relatively large deflection, a mechanism is disclosed for delaying an application of tension on one of the pull wires until at least a portion of any tension on the other pull wire is released.

摘要： An active system for deflecting a distal portion of a catheter into a hoop configuration includes an elongated catheter body having a proximal portion and a distal portion that is formed with a lumen. A thin-walled tube, which is typically made of a metallic material, is positioned in the lumen. The tube includes a cylindrical wall and includes a plurality of lateral slits that are typically formed in the tube wall and arranged such that the tube can be transformed between a relaxed, cylindrical configuration and a deflected configuration wherein the tube is substantially hoop shaped. One end of a deflection wire is attached to the tube and the other wire end is attached to a reel that is rotationally mounted onto a catheter handle housing. In use, the reel is rotated to axially retract the wire and transform the tube into a hoop configuration.

摘要： A CMTS redundancy technique requires at least two CMTS interfaces (e.g., line cards) on one or more CMTS chassis at the head end of a cable network. One of the CMTSs serves as a backup or “protecting” CMTS. When another CMTS (a “working” CMTS) becomes unavailable to service its group of cable modems, the protecting CMTS takes over service to those cable modems. The SWITCHOVER takes place transparently (or nearly transparently) to the cable modems. The protecting CMTS provides service on the same downstream channel as used by the working CMTS. The cable modems need not modify any settings pursuant to their cable modem communication protocol (e.g., DOCSIS ranging). This transparency to the cable modems is realized by keeping the working and protecting CMTSs in synchronization regarding service parameters for the cable modems. In other words, the protecting CMTS maintains a list of current parameters for allowing service to the cable modems.
摘要翻译： CMTS冗余技术在电缆网络的头端的一个或多个CMTS机架上需要至少两个CMTS接口（例如，线路卡）。其中一个CMTS作为备份或“保护”CMTS。当另一个CMTS（“工作”CMTS）变得不可用来为其组的电缆调制解调器服务时，保护CMTS将接管这些电缆调制解调器的服务。 SWITCHOVER透明地（或几乎透明地）发送到电缆调制解调器。保护CMTS在工作CMTS使用的同一下行信道上提供服务。电缆调制解调器不需要根据其电缆调制解调器通信协议（例如，DOCSIS测距）来修改任何设置。电缆调制解调器的透明度通过保持工作和保护CMTS与电缆调制解调器的服务参数同步而实现。换句话说，保护CMTS维护用于允许对电缆调制解调器的服务的当前参数的列表。
