    摘要： 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.

    摘要： The present invention includes systems, methods, and apparatus configured to close an internal tissue opening, such as an internal tissue opening cased by an atrial septal defect including a patent foramen ovale defect, ventricular septal defect, patent ductus arterosus defect, or the like. For example, a closure device includes a right anchor cooperatively coupled with a left anchor, where the right anchor and left anchor are configured to be positioned about the internal tissue opening. The left and/or right anchor are configured to close the internal tissue opening in one instance, and to provide tissue stimulating or growth-encouraging substances at the tissue opening. Additional aspects of the invention relate to shape, formation, positioning, and detachment of the closure device about the internal tissue opening.

    摘要： 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.
