摘要： Systems and methods for epicardial electrophysiology and other procedures are provided in which the location of an access needle may be inferred according to the detection of different pressure frequencies in separate organs, or different locations, in the body of a subject. Methods may include inserting a needle including a first sensor into a body of a subject, and receiving pressure frequency information from the first sensor. A second sensor may be included with the access needle to provide image data and/or cardiac waveform information of the subject.

摘要： System and method that is directed to medical treatments of organs having anatomical spaces, such as (but not limited to) the heart and the pericardial space. Specifically, an apparatus and method is provided for safely accessing anatomical spaces with surfaces to deliver medical devices or media into such spaces, or to remove fluids from such spaces. The methods and apparatus may include a first elongated member with a sharp tip used to penetrate the surface surrounding the anatomical space with a second elongated member with a helical tine used to engage the surface and lift the surface away from the underlying anatomical space. Once the first elongated member has incised the surface, it is removed, and the incision may be used as a point of entry for delivering media or medical devices into the anatomical space, or for carrying out further medical procedures.

摘要： The epicardial pacing system and related method includes an epicardial catheter configured to be disposed in the middle mediastinum of the thorax of a subject for use in electrical pacing of the heart at one or more locations on the epicardial surface. The epicardial pacing catheter may include at least one electrode whereby the electrode is insulated on at least one side to allow pacing of the heart without damage to adjacent anatomical structures.

摘要： An aspect of various embodiments of the present invention system and method provide, but not limited thereto, a novel means for epicardial ablation using a double-curve steerable sheath and a double-curve deflectable open irrigated-tip/suction catheter that can be guided around the apex of the heart and adjusted so as to position the distal tip optimally. The catheter can also both deliver fluid to and withdraw fluid from the pericardial space. Access to the epicardial surface of the heart is via a subxiphoid entry. The method and means presented include, but are not limited to, steering, energy delivery, bipolar mapping, placement and use of electrodes, irrigation, suction of irrigation fluid, and other details of the subject invention.
