20090118727 | ABLATION DEVICES AND METHODS OF USING THE SAME - Devices and methods for ablating a selected tissue volume, such as for ablating tumor, are disclosed. In certain embodiments, the ablation devices include a low-conductivity, tissue-piercing tip, an adjustment mechanism for selectively adjusting the length of an exposed portion of the electrode, for producing ablation volumes of desired geometry. In other embodiment, the methods allow the adjustment of the length of the exposed electrode portion be carried out by moving an insulative sleeve along the electrode. | 05-07-2009 |
20110190767 | Cavity Ablation Apparatus and Method - Ablation devices and associated methods are provided for use in ablating the margin of a cavity such as a surgical or body cavity. The ablation apparatus includes an integral or connected elongate probe and an elongate sleeve. Suction can be applied with a vacuum source operably connected to the proximal end region of the sleeve, whereby tissue of the surgical cavity is drawn against the surface of the sleeve. The probe includes one or more electrodes disposed at the probe's distal end region, for ablating tissue when the electrode(s) are activated to create an ablated margin of tissue at least partially surrounding the surgical cavity. | 08-04-2011 |
20120150172 | Multi-Electrode Energy Delivery Device and Method of Using the Same - An energy delivery device for treating a patient includes a probe body and a plurality of elongate electrode elements that extend radially away from the probe body when deployed into tissue of the patient. The electrode elements are adapted to receive electrical treatment energy such as irreversible electroporation (IRE) pulses from an energy source. In one embodiment, each electrode element has a longitudinally varying electrical resistance at the electrode-tissue interface along the electrode so as to provide a uniform electric field along the length of the electrode. The uniform electric field allows a more uniform ablation of tissue within a treatment zone. | 06-14-2012 |
20130090646 | Multiple Treatment Zone Ablation Probe - An energy delivery probe and method of using the energy delivery probe to treat a patient is provided herein. The energy delivery probe has at least one probe body having a longitudinal axis and at least a first trocar and a second trocar. Each trocar comprises at least two electrodes that are electrically insulated from each other, and each electrode is independently selectively activatable. An insulative sleeve is positioned in a coaxially surrounding relationship to each of the first trocar and the second trocar. The probe also has a switching means for independently activating at least one electrode. The method involves independently and selectively activating the first and second electrodes to form an ablation zone, then repeating the ablation by delivering energy to a second set of electrodes, producing one or more overlapping ablation zone, and eliminating the need to reposition the ablation probes. | 04-11-2013 |
20140081255 | Method and Apparatuses for Tissue Treatment - Disclosed in the present application are devices for localized delivery of energy and methods of using such devices, particularly for therapeutic treatment of biological tissues. The disclosed devices may contain one or more energy delivery members. The disclosed methods may involve positioning and deploying the energy delivery members in a target site, and delivering energy through the energy delivery members. | 03-20-2014 |
20140121663 | Irreversible Electroporation (IRE) for Congestive Obstructive Pulmonary Disease (COPD) - A method for treating Chronic Obstructive Pulmonary Disease (COPD) or chronic bronchitis to alleviate the discomforts of breathing by using non-thermal electroporation energy to ablate diseased portions of the lung including the bronchus, airways and alveoli which, in effect, opens the restrictive diseased portions thereby maximizing the overall surface area thereof causing improved airflow and uninhibited breathing. | 05-01-2014 |
20140378964 | Methods of Sterilization and Treating Infection Using Irreversible Electroporation - A method for treating an infection using irreversible electroporation is presented. The method includes providing an ablation device that has at least one electrode and inserting the ablation device into a target tissue of a patient. The tissue at least partially surrounds the implanted medical device. The outer surface of the medical device is at least partially covered by infectious cells. The method also involves positioning at least one electrode in or near the implanted medical device and delivering electrical pulses to or near the implanted medical device sufficient to irreversibly electroporate the infectious cells. | 12-25-2014 |
20150250474 | SURGICAL IMPLANT AND METHOD AND INSTRUMENT FOR INSTALLING THE SAME - A surgical implant comprising a receiver member and deployment member for clamping and sealing tissue of variable thickness, a corresponding applicator tool and surgical system for connecting, sealing, fastening and/or attaching tissue to itself, to other tissue and/or to non-tissue structures, and/or sealing the flow of fluid at and/or between structures such as tissue and vessel structures. | 09-10-2015 |
