    摘要: Methods and systems for securing tissues, e.g., cardiovascular tissues, are disclosed. A method in accordance with one embodiment of the invention includes inserting a portion of a catheter into an opening between a first portion of cardiovascular tissue and a second portion of cardiovascular tissue. The method can further include drawing the first and second portions of the cardiovascular tissue into contact with each other by drawing a vacuum in a region adjacent to the first and second portions of cardiovascular tissue via the catheter while the catheter is positioned between the first and second portions. The tissue portions can be fused by heating the tissue from within the opening, e.g., via radio frequency energy. This technique, and associated catheter system, can be used to close a patent foramen ovale or other openings in cardiovascular tissue.

    摘要: Systems and methods for securing cardiovascular tissue, including via asymmetric electrodes, are disclosed. A device in accordance with one embodiment includes a catheter having a proximal end and a distal end, with a working portion positioned toward the distal end and being elongated along a terminal axis. The device can further include an energy transmitter (e.g., an electrode) at the working portion of the catheter, with the energy transmitter tapered inwardly toward the terminal axis in a distal direction. The energy transmitter can be asymmetric relative to the terminal axis. In further particular embodiments, other components of the catheter (e.g., an inflatable member, guidewire conduit, and/or catheter bend angle) can also be asymmetric relative to the terminal axis, and in still further particular embodiments, some or all of the foregoing elements can have particular alignments relative to each other.
