Publication number: 20090076501Abstract: Devices and methods provide for ablation of cardiac tissue for treating cardiac arrhythmias such as atrial fibrillation. Although the devices and methods are often be used to ablate epicardial tissue in the vicinity of at least one pulmonary vein, various embodiments may be used to ablate other cardiac tissues in other locations on a heart. Devices generally include at least one tissue contacting member for contacting epicardial tissue and securing the ablation device to the epicardial tissue, and at least one ablation member for ablating the tissue. Various embodiments include features, such as suction apertures, which enable the device to attach to the epicardial surface with sufficient strength to allow the tissue to be stabilized via the device. For example, some embodiments may be used to stabilize a beating heart to enable a beating heart ablation procedure. Many of the devices may be introduced into a patient via minimally invasive introducer devices and the like.Type: ApplicationFiled: October 21, 2008Publication date: March 19, 2009Applicant: ESTECH, Inc.

Publication number: 20030125604Abstract: Tissue stabilization and ablation devices and methods provide techniques for stabilizing and ablating body tissues during surgical ablation procedures. In many embodiments, for example, devices may be used in minimally invasive techniques for ablating epicardial tissue adjacent one or more pulmonary veins to treat atrial fibrillation. Tissue stabilization and ablation devices generally include a rigidifying bladder coupled with an ablation member. The devices may additionally include a tissue stabilizing bladder or means within the rigidifying bladder for enhancing tissue stabilization. The rigidifying bladder conforms to a tissue surface and then stiffens to help the device hold its shape and position and to stabilize the tissue. The ablation member is then used to ablate an area of tissue. Such cardiac stabilization and ablation devices and methods may be used to ablate one or more patterns on the epicardial surface of a heart to treat atrial fibrillation and/or other cardiac arrhythmias.Type: ApplicationFiled: October 15, 2002Publication date: July 3, 2003Applicant: ESTECH, INC.
