| 20080214986 | GELS WITH PREDETERMINED CONDUCTIVITY USED IN ELECTROPORATION OF TISSUE - Gel compositions with adjusted conductivity are disclosed which compositions are used for directing reversible electroporation and irreversible electroporation of cells and tissue. The gel compositions are also used in a similar manner in order to carry out thermotherapy on cells and tissues. | 09-04-2008 |
| 20080269586 | ELECTROPORATION TO INTERRUPT BLOOD FLOW - A method for disrupting blood flow to undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of vessels supplying blood to the undesirable tissue and through the application of electrical pulses causing blood flow disruption. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The process may further comprise monitoring blood flow and/or infusion of a material such as a chemotherapeutic agent or marker into the blood. | 10-30-2008 |
| 20090247933 | BALLOON CATHETER METHOD FOR REDUCING RESTENOSIS VIA IRREVERSIBLE ELECTROPORATION - Restenosis or neointimal formation may occur following angioplasty or other trauma to an artery such as by-pass surgery. This presents a major clinical problem which narrows the artery. The invention provides a balloon catheter with a particular electrode configuration. Also provided is a method whereby vascular cells in the area of the artery subjected to the trauma are subjected to irreversible electroporation which is a non-thermal, non-pharmaceutical method of applying electrical pulses to the cells so that substantially all of the cells in the area are ablated while leaving the structure of the vessel in place and substantially unharmed due to the non-thermal nature of the procedure. | 10-01-2009 |
| 20090248012 | IRREVERSIBLE ELECTROPORATION DEVICE AND METHOD FOR ATTENUATING NEOINTIMAL - Restenosis or neointimal formation may occur following angioplasty or other trauma to an artery such as by-pass surgery. This presents a major clinical problem which narrows the artery. The invention provides a device and a method whereby vascular cells in the area of the artery subjected to the trauma are subjected to irreversible electroporation which is a non-thermal, non-pharmaceutical method of applying electrical pulses to the cells so that substantially all of the cells in the area are ablated while leaving the structure of the vessel in place and substantially unharmed due to the non-thermal nature of the procedure. | 10-01-2009 |
| 20090326436 | ELECTROPORATION TO DELIVER CHEMOTHERAPEUTICS AND ENHANCE TUMOR REGRESSION - A method is disclosed for disrupting capillary blood flow and trapping materials such as chemotherapeutic agents in undesirable tissue, including cells of a cancerous or non-cancerous tumor. The method involves the placement of electrodes into or near the vicinity of capillary vessels supplying blood to capillaries in the undesirable tissue, and application of electrical pulses causing capillary blood flow disruption. In some cases, the electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body's immune system. The process may further comprise monitoring blood flow and/or infusion of a material such as a chemotherapeutic agent or marker into the blood. | 12-31-2009 |
| 20100160850 | GELS WITH PREDETERMINED CONDUCTIVITY USED IN ELECTROPORATION OF TISSUE - Gel compositions with adjusted conductivity are disclosed which compositions are used for directing reversible electroporation and irreversible electroporation of cells and tissue. The gel compositions are also used in a similar manner in order to carry out thermotherapy on cells and tissues. | 06-24-2010 |
| 20100196984 | CONTROLLED ELECTROPORATION AND MASS TRANSFER ACROSS CELL MEMBRANES - Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation, in general. In addition, a particular method and apparatus are disclosed in which electroporation and/or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought. Electroporation is achieved by applying a voltage between the two chambers, and diffusive transport is achieved either by a difference in solute concentration between the liquids surrounding the cell and the cell interior or by a differential in concentration between the two chambers themselves. Electric current and diffusive transport are restricted to a flow path that passes through the opening. | 08-05-2010 |
| 20110040204 | NEUROLOGICAL STIMULATION AND ANALYSIS - In one embodiment, a method for neurological interrogation and response analysis is provided. The method includes inducing, at the device, a non-optical excitation for a user. The device comprises a wearable device being worn by the user such that the non-optical excitation can be sensed. A response of a voluntary conscious movement is detected from the user. An outcome is analyzed based on the response and the non-optical excitation. An action can be performed in response to the analysis. | 02-17-2011 |
