Clinical trials Below are current clinical trials.57 studies in Neurosurgery (open studies only). Filter this list of studies by location, status and more. A Study Of The Possible Use Of A New Imaging Method With Glioma Tumors Scottsdale/Phoenix, Ariz., Rochester, Minn. The purpose of this study is to see if Magnetic Resonance Elastography (MRE) a recently developed imaging technique can be used to characterize and help stage glioma tumors and evaluate response to therapy. Cerebrospinal Fluid Biomarkers For Brain Tumors Rochester, Minn. The purpose of this study is to help generate a repository of Cerebrospinal Fluid (CSF) samples relevant to neuro-oncology research that may facilitate the identification of biomarkers that are predictive of disease burden, therapeutic susceptibility or response to therapy. This protocol will also provide a vehicle for CSF access for patients or providers wishing to generate or evaluate individualized biomarkers as part of other research or individualized therapy protocols. A Study To Explore If It Is Possible To Successfully Obtain Optical Coherence Tomography (OCT) Imaging And Data While Patients Undergo Brain Surgery Jacksonville, Fla. The goal of this study is to investigate the feasibility of successfully obtaining intra-operative OCT imaging and data during standard brain surgery. Acute Modulation of Stereotyped High-Frequency Oscillations Rochester, Minn. The purpose of this study is to do data collection of EEG findings to determine whether new types analysis of intracranial EEG can add different and possibly useful information to standard types of analysis of intracranial EEG. Intracranial EEG data will be collected intraoperatively and postoperatively during routine clinical monitoring, and will be analyzed by researchers for functional brain mapping and the investigation of high frequency oscillations (HFO's), for the purpose of identifying functional and epileptogenic brain areas. A Study Of Acute Stimulation For The Modulation Of Epileptic Events With A Closed-Loop Brain Interchange System In Drug Resistant Epilepsy Rochester, Minn. The purpose of this study is to investigate the feasibility of detecting and modulating pathological high-frequency oscillations (HFOs) generated by the seizure onset zone (SOZ) of drug-resistant epilepsy patients using CorTec's Brain Interchange Evaluation Kit (manual provided as supplementary material). A Study to Assess Sinus Stenting to Manage Cerebrospinal Fluid Leak Rochester, Minn. The purpose of this study is to determine whether transverse/sigmoid sinus junction stenting reduces the risk of recurrent cerebrospinal fluid (CSF) leak in patients with idiopathic intracranial hypertension presenting with CSF leak. A Study to Evaluate Biomarker Target Stimulation Rochester, Minn. The purpose of this study is to understand how electrical stimulation of the brain can modulate and suppress interictal epileptiform activity as a step on the path to developing new therapies for epilepsy. A Study Of Vagus Nerve Stimulation (VNS) With Mobility Training For Gait Recovery After Chronic Ischemic Stroke Rochester, Minn. The purpose of this study is to evaluate the safety, feasibility, and efficacy of vagus nerve stimulation (VNS) paired with mobility training to improve lower extremity function and gait in individuals with chronic ischemic stroke. A Study To Evaluate The Feasibility Of Intraoperative Microdialysis (Tissue Sampling) During Neurosurgery For Central Nervous System Malignancies Rochester, Minn. Intraoperative Microdialysis During Neurosurgery for Central Nervous System Malignancies A Multimodal Monitoring (MMM) Computer to Detect Physiologic Trends in Data in Neurointensive Care Unit Patients Rochester, Minn., Jacksonville, Fla. The purpose of this study is to identify important physiologic trends in bedside ICU data such as cerebral perfusion pressure (CPP), intracranial pressure (ICP) using a bedside “Multimodal monitoring” (MMM) computer which utilizes ICM+ Cambridge software.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
