    • A stent delivery and apposition detecting system includes at least one electrode pair of dissimilar metals mounted on a balloon of a balloon catheter. The electrode pair forms part of an electrochemical cell, and voltage and current generated from the electrochemical cell enables the system to detect when a stent mounted on the balloon achieves proper wall apposition. As the balloon is exposed to different environments, i.e., blood or tissue having different resistances, the electric potential of the electrochemical cell changes and an alert is generated by a feedback circuit to notify a user that the electrodes are in contact with tissue of the vessel wall. In one embodiment, the feedback circuit may be powered by the electrochemical cell. Multiple sets of electrode pairs may be mounted along the circumference and length of the balloon to detect differential contact between the deployed stent and the vessel wall.
    • 支架输送和并置检测系统包括安装在球囊导管的球囊上的至少一个不同金属电极对。 电极对形成电化学电池的一部分,并且从电化学电池产生的电压和电流使得系统能够检测何时安装在气囊上的支架实现适当的壁连接。 当气囊暴露于不同的环境,即具有不同电阻的血液或组织时,电化学电池的电位发生变化,并且由反馈电路产生警报,以通知用户电极与血管的组织接触 壁。 在一个实施例中,反馈电路可以由电化学电池供电。 可以沿着球囊的圆周和长度安装多组电极对,以检测部署的支架和血管壁之间的不同接触。

    • A continuous feed line trimmer in which the spool or container of reserve cutting line is mounted independently from the trimmer. The trimmer having a set of gears or rollers that pull the cutting line from the spool or container forcing it through a hollow tube then through a hollow rotating shaft and then through a rotating cutter head to cut vegetation. By mounting the reserve spool or container of cutting line independently of the trimmer the footage of cutting line held in reserve is increased dramatically, thereby enormously reducing the downtime used to replenish cutting line. Trimmer can be mounted as a stand alone unit with its own power source or can be mounted as an auxiliary attachment on mowers, tractors etc.
    • 连续进料线修剪器,其中备用切割线的卷轴或容器独立于修剪机安装。 修剪器具有一组齿轮或辊,其将切割线从卷轴或容器拉出,迫使其穿过中空管,然后穿过中空旋转轴,然后通过旋转刀头切割植被。 通过独立于修剪器安装切割线的备用卷轴或容器,保留的切割线的镜头显着增加,从而大大减少了用于补充切割线的停机时间。 修剪机可以作为独立的单元安装,具有自己的电源,或者可以作为辅助附件安装在割草机,拖拉机等上。

    • An apparatus for thermal treatment of tissue, includes an outer member having a frame dimensioned for engagement with the hand of a surgeon and an elongated portion connected to the frame and extending distally therefrom. The elongated portion defines a longitudinal axis and has an axial opening. An electromagnetic probe assembly is releasably mounted to the outer member. The electromagnetic probe assembly includes a handle and an electromagnetic probe connected to the handle. The electromagnetic probe is at least partially positionable within the axial opening of the elongated portion and is adapted for reciprocal longitudinal movement therewithin between a non-deployed position and a deployed positions. A manually operable release member releasably mounts the electromagnetic probe assembly to the outer member. The release member is dimensioned and positioned for manual manipulation to move between a first position engaging the electromagnetic probe assembly and preventing release thereof from the outer member, and a second position releasing the electromagnetic probe assembly to thereby facilitate assembly and disassembly of the electromagnetic probe assembly with respect to the outer member.
