Abstract:
A system is disclosed for incorporating a realistic simulated catheter or catheters within a catheter guidance and control system that operate from the same closed-loop position control feedback and geometric mapping data as the real position control system and are able to make contact with real and simulated datasets. These catheters may be operated in a pure simulation mode without interacting with real catheters and position control hardware, or may be used as control cursors to enhance the placement of catheter positioning targets. The catheter tip, which is focus of magnetic control, is realistically guided by the control system parameters, while the remainder of the catheter line is realistically constrained by the mapped chamber geometry and introducer sheath.

Abstract:
Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed. A system for the application of microwave energy to a tissue includes a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue. The applicator includes one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to the tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue includes a first layer and a second layer, the second layer below the first layer. The controller is configured so that the system delivers energy such that a peak power loss density profile is created in the second layer.

Abstract:
A system and method is described for a catheter guidance system which allows an operator to use a mapping catheter to specify tissue target locations for the automatic guidance of a second therapeutic catheter. The operator places a mapping catheter at a desired location, and commands the catheter guidance system by either selecting a point on that catheter or one of the catheter electrode electrocardiograms. The operator may target the selected dynamic location, or tissue contact beyond that location on a specific side of the mapping catheter.

Abstract:
This invention is an improved tissue-localizing device with an electrically energized locator element for fixedly yet removably marking a volume of tissue containing a suspect region for excision. The electrical energizing of the locator element facilitates the penetration of the locator element in to subjects tissue and minimizes resistance due to dense or calcified tissues. At least one locator element is deployed into tissue and assumes a predetermined curvilinear shape to define a tissue border containing a suspect tissue region along a path. Multiple locator elements may be deployed to further define the tissue volume along additional paths defining the tissue volume border that do not penetrate the volume. Delivery of electric cut-rent may be achieved through monopolar or bipolar electronic configuration depending on design needs. Various energy sources, e.g., radio frequency, microwave or ultrasound, may be implemented in this energized tissue-localizing device.
