An access system and method for obtaining access to the interior vascular structures or other regions or collections of fluid or fluid-filled cavities inside the body. The system and method provides for injection of contrast agents (to confirm ideal position or condition), the passage of guide wires, and the eventual catheterization of the heart and other parts of the body via the pathway established through the puncture of a femoral artery. The system and method provides the ability to inject a contrast material and pass a guide wire through the same introducer device simultaneously (without necessarily moving it or removing any parts), with the device designed to prevent the backflow of the contrast material through the guide wire port during the contrast injection process The ideal location of access in the vein or artery can be seen by injecting contrast from a needle inside the structure and then using fluoroscopy.

An aspect of various systems and methods provides, but not limited thereto, novel means for simulating physiological systems and processes in vitro in order to test surgical devices and train practitioners in the use of surgical devices. An aspect of various embodiments further provides in vitro anatomical components, such as a thorax, lungs, heart and pericardium, configured to contain at least one fluid having a pressure-frequency profile that may mimic typical pressure-frequency waveforms of in vivo anatomical fluids. A model communication system may be used to communicate the desired pressure-frequency profiles to the in vitro anatomical fluids. In a further aspect of various embodiments, an access device, e.g. a surgical instrument, configured to sense pressure, frequency, and/or a pressure-frequency profile may be inserted into one or more anatomical components of the in vitro model in order to test the instrument and/or train a practitioner in proper use of the instrument. An access device communication system may be used to communicate data to the practitioner. This data may include, for example, pressure-frequency data and/or the location of a portion of the access device with respect to the various in vitro anatomical components.

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.

A tool and method of positioning and delivering medical devices and therapeutics within the pericardial space, as well as other body part or space. A needle is inserted into the chest through a sub-xiphoid puncture, and the pressure within the needle is monitored manometrically or otherwise sensed as the needle is advanced towards the pericardial space. By reading the pressure within the needle while it is advanced, the clinician is able to know that he or she is avoiding insertion of it into organs or spaces not intended to be the target location. In addition the retractable sharp edge allows the operator to access the space and cut tissue but do so safely by retracting the sharp edge.

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.

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.

An electrode catheter for use with an endocardial ablation catheter, wherein the electrode catheter receives the transmitted energy for ablating a portion of the heart. The electrode catheter comprises a proximal portion, a distal portion, and a longitudinal structure there between; and an electrode in communication with said electrode catheter, wherein said electrode receives the transmitted energy from the endocardial ablation catheter, or alternatively an epicardial ablation catheter.
