    • Medical tubing having a wall formed of multiple strands bonded together. One method for making the tubing utilizes multiple spools containing polymeric strands disposed about a central mandrel, with the strands aligned with and disposed evenly about the mandrel, with both mandrel and strands entering a die or other bonding device. Adjacent strands are bonded together to form a tube wall, the tube preferably having at least one lumen therethrough. Adjacent strands are lightly bonded in some embodiments and highly bonded in others. Bonding can be accomplished using heat, solvent welding, or adhesive. The strands making up the tube wall can be formed of materials differing between strands. One use of the tubing is for constructing angioplasty catheters.
    • 具有由多根股线结合在一起形成的壁的医用管。 用于制造管道的一种方法是利用多个线轴,其包含围绕中心心轴设置的聚合物股线,其中股线与心轴对准并且均匀地围绕心轴布置,心轴和股线都进入模具或其它结合装置。 相邻的股线结合在一起以形成管壁,该管优选地具有通过其中的至少一个内腔。 在一些实施方案中相邻的链是轻度键合的,并且在其它实施方案中高度结合。 可以使用热,溶剂焊接或粘合剂来实现粘合。 构成管壁的线可由不同股线之间的材料形成。 管的一种用途是用于构建血管成形术导管。

    • A mechanism for tracking the state of a plurality of memory banks in a memory device includes a register which has a plurality of bits, with each bit corresponding to one of the memory banks in the memory device. An open bank circuit has an output coupled to the register and is responsive to both a bank select signal which identifies a first memory bank and an open signal, to set a register bit associated with the first memory bank. A close bank circuit has an output coupled to the register and is responsive to the bank select signal which identifies a second memory bank as well as a close signal to reset the register bit associated with the second memory bank and any banks adjacent to the second memory bank.
    • 用于跟踪存储器件中的多个存储体的状态的机构包括具有多个位的寄存器,每个位对应于存储器件中的一个存储体。 开路组电路具有耦合到寄存器的输出,并响应识别第一存储体和开启信号的存储体选择信号,以设置与第一存储体相关联的寄存器位。 闭路电路具有耦合到寄存器的输出,并且响应于识别第二存储器组的存储体选择信号以及闭合信号以复位与第二存储体相关联的寄存器位和与第二存储器相邻的任何存储体 银行。

    • A stent delivery catheter comprising an elongated catheter shaft having a mounting region at the distal end for mounting a stent thereon. The elongated catheter shaft has a lumen therein for receiving an inner shaft. An inner shaft is movably carried within the lumen of the elongated catheter shaft. Extending distally from the distal end of the inner shaft is a tip. A retractable sheath extends proximally from the proximal end of the tip. The sheath, in an unretracted position covers the mounting region of the elongated catheter shaft. In use, once the catheter is in the desired bodily location, the inner shaft is moved in a distal direction relative to the elongated catheter shaft which causes the retractable sheath to be moved in a distal direction relative to the mounting region thereby exposing the stent for delivery.
    • 一种支架输送导管,其包括细长的导管轴,其具有在远端处的安装区域,用于在其上安装支架。 细长的导管轴具有用于容纳内轴的内腔。 内轴可移动地承载在细长导管轴的内腔内。 从内轴的远端向远端延伸的是尖端。 可伸缩护套从尖端的近端向近端延伸。 处于未收缩位置的鞘覆盖细长导管轴的安装区域。 在使用中,一旦导管处于所需的身体位置,内轴相对于细长的导管轴在远侧方向上移动,这使得可伸缩护套相对于安装区域在远侧方向上移动,从而暴露支架 交货。
