Epilepsy affects over 65 million people worldwide and approximately 30% of sufferers do not respond to drugs. For these people, electrodes are placed in the brain to monitor brain activity and stop the initiation or progression of seizures. However, state-of-the-art devices require risky open-brain surgery. In this project, we are developing a Stentrode Neuro-Stimulator (SNS) for the treatment of drug-resistant epilepsy without the need for open-brain surgery.
EXTEND-IA Randomized Trial Of Intra-arterial Clot Retrieval In Ischemic Stroke

Summary
Most strokes are caused by a blocked blood vessel in the brain. Current treatments to dissolve the blockage improve recovery for many patients but often fail to unblock larger brain arteries. The EXTEND-IA trial will use advanced brain imaging to identify patients who have the most to gain if the blocked artery can be re-opened. The trial will test whether a new minimally invasive clot removal procedure performed after standard clot-dissolving treatment improves recovery after stroke.
Prospective Evaluation Of A Model To Predict Outcomes Following Endovascular Aortic Aneurysm Repair

Summary
Once present, abdominal aortic aneurysms tend to enlarge over time resulting in an increased risk of death if they rupture. Endovascular aneurysm repair may be used to fix the aneurysm but this procedure can result in complications over time. We developed a model that uses pre-operative information to predict the chance of an individual having poor results.This study aims to assess whether the model is a good predictor of outcomes and whether extra information will improve its accuracy.
Renal Artery Denervation Performed With Noncontact Circumferential Endovascular Ablation Using A Novel Microwave Catheter

Summary
High blood pressure is a common medical condition leading to death and disability. Some people with high blood pressure do not respond to medical treatment due to abnormal signals from the kidneys that tell the body to increase the blood pressure. We have designed a microwave catheter that can be placed inside the kidney artery and used to heat the kidney nerves around it to stop the relay of these messages. This will lower blood pressure for people who cannot control it with medications alone.
Optimizing Stroke Therapy - Advanced Brain Imaging And Reperfusion Therapies

Summary
Most stroke is due to a blocked blood vessel reducing blood flow to the brain. This research aims to optimize fast restoration of blood flow to the brain and improve patient outcomes. We will test potentially more effective clot-dissolving medication, examine potential benefits of redesigning pre-hospital ambulance transport systems and clarify the role of advanced brain imaging to maximize delivery of recently proven minimally invasive procedures to physically remove blood clots in the brain.

Summary
Aneurysmal disease is an age related phenomenon. The mean life expectancy of western populations has doubled in 100 years because of the reduction in deaths from preventable and treatable diseases, and prolongation of life with chronic and incurable diseases. The older community (>65 years) continues to be active and productive contrary to prior predictions. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community.

The mean life expectancy of western populations has doubled in 100 years because of the reduction in deaths from preventable and treatable diseases, and prolongation of life with chronic and incurable diseases. The older community (>65 years) continues to be active and productive contrary to prior predictions. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. As with many other diseases, prophylaxis against aneurysmal disease is the most effective approach since 80% of those that rupture will result in death. Endoluminal grafting provides a much less invasive procedure and provides an attractive and elegant alternative to open surgery. The danger is that structural strengths will be compromised with failures due to lack of strength and inadequate device durability. The most practical endografts are those that are built up from modules but vulnerable sites affected by fatiguing and disruptive forces are being identified, in particular where a tube divides into two outflow channels – the bifurcation - and joins. To improve and protect the current device, and enable sound engineering for future devices, we need to know the nature, magnitude and location of these forces. The existing collaboration with medical specialist, Cook Aust., the Advanced Fluid Dynamics Laboratory (CSIRO, Melb.) and University of WA combines a multidisciplinary team working towards the design and durability of the next generation of endoluminal devices and percutaneous insertions. While Australia is at the forefront of development, its current place in the market can only be maintained by further product development. Optimising and improving endoluminal grafts will reduce the suffering of major surgery while prolonging a higher quality of life with a much less invasive procedure whose long-term effectiveness, and thereby acceptance is dependent upon reliable durability.Read moreRead less
Minimal Structural Strength Required In Endoluminal Devices For Aortic Aneurysms: Mechanisms Of Rupture When They Fail.

Summary
Aneurysmal disease is an age related phenomenon. The mean life expectancy of western populations has doubled in the last 100 years mainly because of the reduction in deaths from occlusive cardiovascular disease. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. The impact of this work would be to improve minimally invasive, effective prophylaxis against aneurysm of the abdominal aorta since 80% of those that rupture will result in death.

The mean life expectancy of western populations has doubled in the last 100 years mainly because of the reduction in deaths from occlusive cardiovascular disease. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. The impact of this work would be to improve minimally invasive, effective prophylaxis against aneurysm of the abdominal aorta since 80% of those that rupture will result in death. Endoluminal grafting provides a much less invasive procedure and provides an attractive and elegant alternative to open surgery. The general drive in this field is towards miniaturisation. The danger is that structural strengths will be compromised with early failures due to lack of strength; and late failures due to inadequate device durability. This application proposes the development of a collaborative venture with the Department of Vascular Surgery, Royal Perth Hospital, Cook R and D (WA), the Advanced Fluid Dynamics Laboratory (CSIRO, Melbourne) and Centre for Health Services Research (University of WA) to investigate the dynamic flow forces involved in aneurysms of the abdominal aorta. It combines together expertise and facilities to examine the forces acting upon endoluminal stent grafts in pulsatile high pressure environments, the impact on the design, patency, effectiveness and longer-term outcomes. The multidisciplinary team provides a comprehensive approach for this developing area of high technology surgery throughout Australia and internationally. The benefits of this study will directly influence the design and durability of the next generation of endoluminal devices and percutaneous insertions. While Australia is at the forefront of development, its current place in the market can only be maintained by further product development.Read moreRead less

Summary
This research proposal aims to investigate the potential utility of a novel, Australian designed dianostic laser system. A tube positioned in the lungs takes real-time images of the shape and size inside the airways. This can have both clinical and research benefits. It may help doctors choose the right size hardware when opening up cancerous airways and it will help us understand disease mechanisms of lung diseases by studying parts of the airways not previously able to be measured.
