    • A suture anchor is provided which includes a hollow member having an outer surface defining an enclosure therein, the member having a longitudinal axis and a slot through a portion of the outer surface in a direction transverse to the longitudinal axis, the slot providing an opening into the enclosure. The suture anchor further includes a one-way valve positioned within the enclosure at the slot to allow entry of a suture through the slot into the enclosure and to prevent the exit of the suture from the enclosure. A device is provided for deploying the suture anchor. The deployment device includes an elongate hollow member having a suture anchor release zone positioned at the distal end thereof, a launch bar having at least a portion thereof positioned in the release zone, wherein the launch bar is movable within the release zone between a resting position and a launching position and is operatively connected to an actuation member positioned proximally to the elongate member. The hollow elongate member defines a housing for receiving a plurality of suture anchors in tandem along the longitudinal axis of the hollow member, wherein each of the suture anchors is configured for release from the release zone when such suture anchor is positioned within the release zone upon movement of the launch bar from the resting position to the launching position.
    • 提供了缝合锚,其包括具有限定其中的外壳的外表面的中空构件,所述构件具有纵向轴线和穿过外表面的横向于纵向轴线的一部分的狭槽,所述狭槽提供开口 外壳。 缝合锚还包括位于外壳内的单向阀,该单向阀位于狭槽处,以允许缝线通过狭槽进入外壳并防止缝合线从外壳排出。 提供了用于展开缝线锚的装置。 展开装置包括细长的中空构件,其具有位于其远端处的缝合线锚释放区,发射杆至少有一部分位于释放区中,其中发射杆可在释放区域内在静止位置 和发射位置,并且可操作地连接到位于细长构件的近侧的致动构件。 中空细长构件限定了用于沿着中空构件的纵向轴线串联地接收多个缝合锚的壳体,其中每个缝合线锚构件被构造成当这种缝合锚固件位于释放区域内时从释放区域释放, 发射杆从静止位置移动到发射位置。

    • An apparatus for heat ablation of the internal wall of a hollow organ such as the oesophagus comprises a catheter having at least one internal lumen, a balloon located at the distal end of the catheter and attached to a lumen, a supply of a liquid for filling the balloon via the lumen, a tuned microwave antenna located in the region of the balloon for radiating microwave energy at a predetermined frequency to heat the balloon to a temperature suitable for heat ablation of the hollow organ wall tissue, a waveguide for supplying microwave energy to the microwave antenna, and a temperature probe to measure the temperature of the balloon. The balloon is filled from the proximal end of the catheter with a liquid having a dielectric constant of from 41 to 63 and a conductivity of from 1.0 Sm−1 to 1.5 Sm−1.
