    • A medical system and device for use in delivering RF energy to a tissue opening and a method for determining an RF dose is disclosed. In one embodiment, the medical device includes an electrode or anchor and one or more devices, such as an impedance electrode, RF electrode and/or thermocouple. The electrode or anchor can be deployed from a delivery shaft inside the left atrium, for example, of a heart and substantially conform to the tissue proximate the tissue opening. Tissue characteristics, such as temperature and/or impedance, can be measured, before, during and after application of RF energy to the tissue, by one or more devices to determine an RF dose. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.
    • 公开了一种用于将RF能量递送到组织开口的医疗系统和装置以及用于确定RF剂量的方法。 在一个实施例中,医疗装置包括电极或锚定器以及一个或多个装置,例如阻抗电极,RF电极和/或热电偶。 电极或锚固件可以从左心房内的输送轴例如心脏展开,并且基本上符合组织开口附近的组织。 组织特征如温度和/或阻抗可以在RF能量施加到组织之前,期间和之后由一个或多个装置测量以确定RF剂量。 在将能量施加到左右电极之间的组织之后,左电极可以通过被收回到输送轴中而从左心房移除,此后从开口移除输送轴。

    • A medical system for use in reducing the size of an internal tissue opening is disclosed. The medical system can include a patent foramen ovale or PFO closure device and a delivery device therefore. The PFO closure device can include left and right anchors connected by a stem. The delivery device is configured to selectively deploy at least one of the right or left anchors of PFO closure device so as to enable a practitioner to adjust PFO closure device during the positioning procedure. In one embodiment, the delivery device includes a filament operating shaft linked to the right anchor by one or more filaments. A practitioner can move the filament operating shaft to selectively deploy and retract the right anchor during positioning of the PFO closure device. Furthermore, the delivery device comprises a tether shaft for coupling delivery device to PFO closure device. In one embodiment, the tether shaft comprises a first portion and a flexible second portion, wherein the flexible second portion is at a distal end of the tether shaft.
    • 公开了一种用于减小内部组织开口尺寸的医疗系统。 因此,医疗系统可以包括卵孔或PFO封闭装置和输送装置。 PFO闭合装置可以包括由杆连接的左和右锚定件。 输送装置构造成选择性地展开PFO闭合装置的右或左锚固件中的至少一个,以使得从业者能够在定位过程期间调节PFO闭合装置。 在一个实施例中,输送装置包括通过一个或多个细丝连接到右锚的细丝操作轴。 在定位PFO闭合装置期间,从业者可以移动细丝操作轴以选择性地展开和缩回右锚。 此外,输送装置包括用于将输送装置耦合到PFO闭合装置的系绳轴。 在一个实施例中,系绳轴包括第一部分和柔性第二部分,其中柔性第二部分位于系绳轴的远端。
