Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device. The Holy Grail for developers of rotary blood pumps used as left ventricular assist devices is to control the pump to meet the body's metabolic demand and to do this without the need for implanting additional sensors. The controller must also detect and avoid dangerous states associated with over and under pumping.
In this research we will derive and implement a pump control algorithm that will ....Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device.

A kinetic measuring system for assistive devices used in paediatric gait. Each year, a proportion of children are born who suffer from disabilities, which limits their ability to walk efficiently. Gait analysis can identify limiting factors in walking ability, and can assess the clinical outcome of treatments. Children who use assistive devices, such as walking frames, are denied the full benefits of gait analysis due to limitations in current equipment. This project addresses this need through ....A kinetic measuring system for assistive devices used in paediatric gait. Each year, a proportion of children are born who suffer from disabilities, which limits their ability to walk efficiently. Gait analysis can identify limiting factors in walking ability, and can assess the clinical outcome of treatments. Children who use assistive devices, such as walking frames, are denied the full benefits of gait analysis due to limitations in current equipment. This project addresses this need through the development of a portable, load-measuring instrument. When integrated with existing equipment, a comprehensive description of assisted walking gait will be possible. This will lead to greater understanding and improved treatment outcomes for such children.Read moreRead less

Scaffolds for bone tissue regeneration and use in orthopaedic applications. Damaged joints do not repair spontaneously, often leading to arthritis. Bone defects resulting from congenital defects or disease processes are challenging to regenerate and represent a major financial burden to our health system.

However they lack the combined physical/biolo ....Scaffolds for bone tissue regeneration and use in orthopaedic applications. Damaged joints do not repair spontaneously, often leading to arthritis. Bone defects resulting from congenital defects or disease processes are challenging to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. This created a need for scaffolds to provide temporary support for new bone. However they lack the combined physical/biological properties necessary for bone repair. We developed new scaffolds with improved mechanical/biological properties to mimic bone which will lead to new treatments for bone damage.Read moreRead less
