| 20100049276 | Clinician programmer system and method for calculating volumes of activation for monopolar and bipolar electrode configurations - A system and method for providing a volume of activation (VOA) of a stimulation electrode leadwire may include a processor that calculates a VOA for each of a plurality of sets of parameter settings of the leadwire, stores in a database each of the calculated VOAs in association with the respective set of parameter settings for which it was calculated, performs a curve fitting on threshold values determined for a plurality of waveforms to obtain an equation, obtains a set of parameter settings of the leadwire for a stimulation, and determines a VOA for the obtained set of parameter settings based on the stored VOAs, for example, using the equation. | 02-25-2010 |

| 20110040351 | SYSTEM AND METHOD TO DEFINE TARGET VOLUME FOR STIMULATION OF THE SPINAL CORD AND PERIPHERAL NERVES - One embodiment provides a computer-implemented method that includes storing a volume of tissue activation (VTA) data structure that is derived from analysis of a plurality of patients. Patient data is received for a given patient, the patient data representing an assessment of a patient condition. The VTA data structure is evaluated relative to the patient data to determine a target VTA for achieving a desired therapeutic effect for the given patient. | 02-17-2011 |
| 20110066407 | Systems and methods for determining volume of activation for spinal cord and peripheral nerve stimulation - This document discloses, among other things, systems and methods for determining volume of activation for spinal cord stimulation (“SCS”) using a finite element model (FEM) circuit to determine a FEM of an implanted electrode and a spinal cord in which the electrode is implanted, a Fourier FEM solver circuit to calculate a potential distribution in the spinal cord using information from the FEM circuit and a capacitive component of at least one of the implanted electrode and the spinal cord, and a volume of activation (VOA) circuit to predict a VOA using the potential distribution and a neuron model. | 03-17-2011 |

| 20090208073 | Brain stimulation models, systems, devices, and methods - This document discusses, among other things, brain stimulation models, systems, devices, and methods, such as for deep brain stimulation (DBS) or other electrical stimulation. In an example, volumetric imaging data representing an anatomical volume of a brain of a patient can be obtained and transformed to brain atlas data. A patient-specific brain atlas can be created using the inverse of the transformation to map the brain atlas data onto the volumetric imaging data and a volume of influence can be calculated using the patient-specific brain atlas. In certain examples, the volume of influence can include a predicted volume of tissue affected by an electrical stimulation delivered by an electrode at a corresponding at least one candidate electrode target location. | 08-20-2009 |

| 20090210208 | Brains stimulation models, systems, devices, and methods - This document discusses, among other things, brain stimulation models, systems, devices, and methods, such as for deep brain stimulation (DBS) or other electrical stimulation. In an example, a target volume of activation (VOA) can be received, a test VOA can be simulated, and at least one of a target electrode location or parameter can be provide using a relationship between the target VOA and the test VOA. | 08-20-2009 |
