The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less
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. The innovative research in this proposal will develop the next generation of surgical bioadhesive technology and claim a s ....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. 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

This project will lead to far more detailed understanding of skull mechanics in our own lineage. Results will be of great interest to international scholars in both evolutionary and biomedical fields and help to establish a primary position for Australia in the rapidly expanding area of computer simulation of biological structure. Further development on our own established protocols for automated transfer of CT scan data into finite element models, which have already improved speed, accuracy and realism, will take finite element analysis to a point at which it can be more readily applied to evolutionary, biomedical and safety design questions.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
Haemodynamic investigation of flow diverter stents for the treatment of intracranial aneurysms. This project will explore the engineering of a flow diverter, an endovascular device for the treatment of brain aneurysms. The project will determine the optimal design of new types of flow diverters, which in turn could improve the effectiveness of treatments, thus reducing the associated costs of cerebral haemorrhage and stroke.

Summary
A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even sm ....A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even small improvements in implant life represent significant cost savings. By accurately simulating conditions within the body, this biomechanical testing facility will lead to new developments in implant designs and materials, in turn improving quality of life, productivity and treatment costs.Read moreRead less
Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently avai ....Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.Read moreRead less
Design and characterisation of a polysaccharide-based biomaterial for tissue adhesion. This proposal aims to design a new bio-adhesive material and study the mechanisms of action for tissue adhesion. Current suture technology is inadequate for anything but simple repairs and the alternative offered by surgical glues available today is at most augmentation of suturing. Combination of a strong adhesive biomaterial with factors for accelerating wound healing will generate a novel material technolo ....Design and characterisation of a polysaccharide-based biomaterial for tissue adhesion. This proposal aims to design a new bio-adhesive material and study the mechanisms of action for tissue adhesion. Current suture technology is inadequate for anything but simple repairs and the alternative offered by surgical glues available today is at most augmentation of suturing. Combination of a strong adhesive biomaterial with factors for accelerating wound healing will generate a novel material technology that, by uniting wound closure with sealing, addresses an unmet need in surgery.
The primary outcomes of these investigations will be:
1. advancement of knowledge in theories of tissue-biomaterial adhesion mechanisms
2. knowledge of effects of visible light from laser diodes on cells and isolated tissue
3. a biocompatible, visible light activated adhesive film for tissue repair based on chitosan polysaccharides

Computational haemodynamics system for prediction of risk of rupture of cerebral aneurysms. Every year about 2000 Australians suffer a ruptured aneurysm in the brain and some 750 of these die within 4 weeks. Since there is an increase in the detection of unruptured aneurysms, especially in healthy young people, there is an urgent need to be able to decide which lead to rupture and to provide suitable treatment options. This project, which will provide markedly improved means of patient-specific ....Computational haemodynamics system for prediction of risk of rupture of cerebral aneurysms.

Since there is an increase in the detection of unruptured aneurysms, especially in healthy young people, there is an urgent need to be able to decide which lead to rupture and to provide suitable treatment options. This project, which will provide markedly improved means of patient-specific risk determination for aneurysm rupture, will have significant impact in reducing associated costs on the national health burden due to cerebral hemorrhage and stroke, on community productivity and disability and on more efficient targeting of expensive and dangerous brain surgery.Read moreRead less
