20110224666 | METHOD OF SURGICAL PERFORATION VIA THE DELIVERY OF ENERGY - 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. | 09-15-2011 |
20120046657 | Stent Graft Fenestration - A method for creating a channel through a foreign material located in a body of a patient, the foreign material defining a material first surface and a substantially opposed material second surface, the channel extending through the foreign material between the material first and second surfaces, the method using an apparatus including an electrode, the method comprising: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel, wherein the foreign material is included in a stent graft. | 02-23-2012 |
20140100560 | Fenestration through foreign material - Described herein is a method for creating a channel through a foreign material located in a body of a patient. The foreign material defines a material first surface and a substantially opposed material second surface and the channel extends through the foreign material between the material first and second surfaces. The method uses an apparatus including an electrode, and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. In some embodiments, the patient's body includes a heart defining a septum, the septum defines an aperture extending there-through and the foreign material extends across the aperture to cover the aperture. | 04-10-2014 |
20140100561 | Fenestration through foreign material - Described herein is a method for creating a channel through a foreign material located in a septum of a heart at the site of a septal defect. The foreign material defines a material first surface and a substantially opposed material second surface, and the channel extends through the foreign material at least partially between the material first and second surfaces. The method uses an apparatus including an electrode and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. | 04-10-2014 |
20140206987 | Medical apparatus for fluid communication - This disclosure describes embodiments of a kit and its constituent components which together form an apparatus in which fluid communication between a medical device's lumen and the surrounding environment is provided by a conduit cooperatively defined by the medical device and a tubular member into which the device is inserted. The medical device and tubular member are configured to fit together such that an outer surface of the distal region of the medical device cooperates with an inner surface of the tubular member to define the conduit between the side-port of the medical device and a distal end of the tubular member. The conduit is operable to be used for injecting fluid, withdrawing fluid, and measuring pressure, for example. Methods of assembling and using the apparatus are described as well. | 07-24-2014 |
