Development of a Light-Activated Bioadhesive for Low Temperature Tissue Repair. While sutures currently represent the gold standard for wound closure, their fundamental technology has changed little in thousands of years. Surgical sealants and energy based closure devices are expected to increasingly replace or complement sutures, improving tissue closure and wound healing.

While sutures currently represent the gold standard for wound closure, their fundamental technology has changed little in thousands of years. Surgical sealants and energy based closure devices are expected to increasingly replace or complement sutures, improving tissue closure and wound healing. The innovative research in this proposal will develop the next generation of surgical bioadhesive technology and claim a stake in the estimated US$ 4 billion market. The project outcomes will enhance Australia's reputation in the biomedical field and will have world-wide social and health care benefits by ultimately allowing better functional healing through bioadhesives that can be effectively applied rapidly and consistently.Read moreRead less

ANATOMICAL ORGAN MODELLING AND SURGICAL PROCEDURE SIMULATION FOR THORACOSCOPIC SURGERY. We aim to establish novel virtual reality-based surgical procedure simulation methodologies, geometric and physical models of human organs, and surgical tools and interaction modules for thoracoscopic surgery or for minimally invasive surgical procedures. This is needed to optimize surgical strategy and to anticipate possible problems that may arise during the procedure, and to train medical staff as the tren ....ANATOMICAL ORGAN MODELLING AND SURGICAL PROCEDURE SIMULATION FOR THORACOSCOPIC SURGERY. We aim to establish novel virtual reality-based surgical procedure simulation methodologies, geometric and physical models of human organs, and surgical tools and interaction modules for thoracoscopic surgery or for minimally invasive surgical procedures. This is needed to optimize surgical strategy and to anticipate possible problems that may arise during the procedure, and to train medical staff as the trend towards robotic-assisted minimally invasive surgery continues. What makes this project novel is the anatomical organ modeling approach based on virtual springs and dampers traversing between the top and bottom surfaces of the organs and tissues, contrary to previous approaches.Read moreRead less
Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic ap ....Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic approach to simulataneuosly simulating the fluid dynamics, the valve motion and the stress in a synthetic Polyether urethane valve is proposed. Cell adhesion study will also be carried out. The findings may yield to new insights into valve research.Read moreRead less

Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and ....Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and development of a suitable biomaterial and optimization of the stent design based on hemodynamics flow analysis and its fabrication with the Fused Deposition Modelling (FDM) process.Read moreRead less
Understanding the biomechanical effects of fixation strategies to improve the technology of fracture management. Severe limb trauma is the leading cause of disability to people of wage-earning age, and 150,000 Australians are hospitalised with fractures each year. Beyond the direct costs to the nation of $1000 million annually, temporary and permanent loss of limb functionality have a significant impact on productivity and quality of life. The computational models developed in this project will ....Understanding the biomechanical effects of fixation strategies to improve the technology of fracture management. Severe limb trauma is the leading cause of disability to people of wage-earning age, and 150,000 Australians are hospitalised with fractures each year. Beyond the direct costs to the nation of $1000 million annually, temporary and permanent loss of limb functionality have a significant impact on productivity and quality of life. The computational models developed in this project will address critical gaps in the knowledge of fracture healing and the influence of different fixation devices. The project outcomes will provide a basis for tailoring fixation technologies for more reliable outcomes and minimised risk of non-union and complications, and thereby reducing physical impairment and the socio-economic burden of fractures.Read moreRead less
In Vitro Study of Hemodynamic Stresses and Endothelialization of Artificial Coronary Arteries. Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces.

Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces. This project aims to investigate the material for manufacturing the artificial artery using Fused Deposition Modeling and to develop methods for the establishment of endothelium on the artificial artery, concluding a restenosis-free solution for by-pass surgery. The knowledge gained through this work would be applicable to the design of other prosthetic devices.Read moreRead less

Transfemoral amputees fitted with an osseointegrated implant are experiencing numerous valuable benefits compare to their previous method conventional attachment. However, 40% of them present an early loosening of the implant or ruptures of the abutment. These problems are related to the load regime acting on the fixation system during post-operative rehabilitation and daily life activities. In this project, the direct measurement of the actual load applied on the abutment during:
· the load bearing exercises is essential to refine the post- operative rehabilitation program.
· every-day activities is crucial to improve the design and
testing of the implants and abutments.Read moreRead less
