  • Four-way steerable catheter system and method of use
    Patent number: 8211025
    Abstract: Certain embodiments provide systems and methods for catheter positioning. Certain embodiments provide a catheter for use in at least intravenous and intracardiac spaces. The catheter includes a catheter body having a length and a tip portion at a distal end of the catheter body. The catheter also includes a plurality of wires for moving the catheter body in a plurality of directions. The catheter further includes a first control for manipulating the plurality of wires in two primary planes of movement for the catheter body. The catheter includes a second control for manipulating the plurality of wires in two secondary planes of movement for the catheter body. The second control is distinct in appearance and operation from the first control.

  • CLINICAL UTILIZATION OF CONTRAST AGENTS TO DEFINE SPECIFIC AREAS WITHIN THE MYOCARDIAL WALL TO PROVIDE GUIDANCE AND LOCALIZATION FOR ABLATION, CYROABLATION, OR OTHER TECHNIQUES IN PATIENTS WITH POST MYOCARDIAL INFARCTION
    Publication number: 20080228079
    Abstract: Certain embodiments of the present invention provide systems and methods for ablating non-viable cardiac tissue. In an embodiment, the method may include locating non-viable cardiac tissue utilizing an electronic medical image. The method may also include locating non-viable cardiac tissue utilizing an ultrasound unit, wherein a contrast agent is used to characterize the non-viable cardiac tissue. The method may also include guiding a catheter to the location of the non-viable cardiac tissue according to the imaging of the ultrasound unit. The method may also include ablating the non-viable cardiac tissue. The ablating of the non-viable cardiac tissue may include cauterizing the non-viable cardiac tissue, cyroablating the non-viable cardiac tissue, or include radiofrequency ablation. The method may also include attempting to locate the non-viable cardiac tissue utilizing an electronic medical image after ablating the non-viable cardiac tissue.
