摘要： Apparatuses and methods for the perforation of heart tissue of a patient when an inferior approach to the heart is contraindicated are disclosed. The method includes using a superior approach to introduce the apparatus, positioning the apparatus at a tissue location and delivering a controlled amount of non-mechanical energy to the tissue to create a perforation. For example, a method of surgical perforation via the delivery of electrical, radiant or thermal energy may include: introducing an apparatus comprising an energy delivery device into a patient's heart via the patient's superior vena cava; positioning the energy delivery device at a first location adjacent material to be perforated; and perforating the material by delivering energy via the energy delivery device; wherein the energy is selected from the group consisting of electrical energy, radiant energy and thermal energy.

摘要： An elongate member for inserting into a cannula is disclosed. The cannula comprises an electrically insulated region and an electrically exposed conductive region for delivering energy to form a lesion within a patient's body at an intended location relative to the electrically exposed conductive region. The elongate member is structured to cooperatively engage with the cannula at a pre-determined insertion depth and to provide a variation in radiopacity, at a pre-determined position relative to the electrically exposed conductive region, when inserted to the pre-determined insertion depth. The variation in radiopacity provides a visual reference for distinguishing, using fluoroscopic imaging, the intended location of the lesion.

摘要： A device with a functional tip containing at least one active electrode capable of creating a controlled perforation in body tissue through the application of Radio Frequency (RF) energy is described. The position of the tip of the device can be determined in response to pressure sensed at the tip and determined by a monitor. The device is useful to remove or perforate unwanted tissue in a controlled manner in any location in the body, particularly in the atrial septum for controlled transseptal puncture. In this application, the device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. Energy is applied to create the perforation and pressure is monitored to determine if the perforation was created in a desired location. Other possible applications include the removal of plaque or thrombotic occlusions from diseased vessels.

摘要： A device for creating a surgical perforation with a functional distal tip for creating a controlled perforation. The functional tip may comprise at least one active electrode for creating the perforation through the application of Radio Frequency (RF) energy. The device is curved in order to decrease the likelihood of injury to structures of a patient such as inadvertent cardiac perforation when used in transseptal perforation procedures. The device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. Energy is applied to create the perforation. The tip is advanced toward the left atrium to create the perforation and as it advances into the left atrium, the device takes on its curved shape to direct the tip away from cardiac structures. The position of the tip of the device can be determined in response to pressure sensed at the tip and determined by a monitor.
