Hand-Held Device and Computer-Implemented Steering of a Percutaneously Inserted Needle

Description

Dr. Mahdi Tavakoli and his team at the University of Alberta have developed a novel hand-held device and methods to enable real-time assisted steering of percutaneously inserted needles, such as those used to deliver brachytherapy seeds to the prostate. The device is compact enough to fit within one hand and enables a surgeon to precisely and […]

Flow Cytometry Sensing Using Diffracted Orders of a Grating

Description

Flow cytometry is a useful tool that employed in diagnoses of various blood diseases, basic research, clinical trials or even as a “cell sorter” instrument. Currently, flow cytometry involves an elaborate arrangement of mirrors and filters to split the signals from the device into the different wavelengths. This setup often requires several lasers and multiple […]

Prosthetic Device For Replacing A Mitral Valve

Description

A University of Alberta researcher has developed a novel design for a percutaneous mitral valve stent that can be deployed using a minimally invasive technique.
Minimally invasive surgery (for example, percutaneous procedures) and transcatheter techniques are rapidly replacing standard surgical techniques. Percutaneous procedures performed through the skin are preferable, as demonstrated by strong patient satisfaction, lower […]

Howard Covering: Novel device to prevent accumulation of biofilm in endotracheal tubes

 
Description

A University of Alberta researcher has developed a novel device to remove accumulated biofilm and prevent further formation of biofilm in endotracheal tubes thereby improving healing rate and preventing infection in patients on respiratory ventilation.
Nosocomial infections are one of the leading causes of death during mechanical ventilation; should the patient survive the infection, their hospital […]

High-Quality, Fast 3D Ultrasound Imaging

Description

3D ultrasound imaging has become of tremendous value in obstetrics, gynaecology, radiology, cardiology, and image-guided surgery and therapy. The increasing use of 3D ultrasound has been due to the limitations of 2D viewing of 3D anatomy using conventional ultrasound. However, despite significant advances in 3D imaging techniques, commercially available technology suffers from low resolution, speed […]

New Cross-Calibration Ion Chamber and Calibration Method for Radionuclide Activity Meters

Direct quality assurance with short-lived clinical isotopes
Description

A portable ion chamber system has been designed for direct calibration of radionuclide activity meters in nuclear medicine and research. The cylindrical chamber accommodates a syringe filled with a specified volume of radionuclide, allowing dose calibrators to be measured against a known quantity of the short-lived radio isotopes actually […]

BioEngineered Adipocytes for the Light-Controlled Release of Insulin

Description

Dr. Peter Light at the University of Alberta has developed genetically engineered adipocytes that secrete significant amounts of bioactive insulin upon exposure to a particular wavelength of blue light. Insulin secretion is specific and very little insulin is secreted in the absence of light. This technology is currently being evaluated as an insulin replacement therapy […]

New Point of Care Diagnostic for Acute Mesenteric Ischemia

Description

University of Alberta researchers are developing a novel non-invasive diagnostic test for acute mesenteric ischemia (AMI). AMI has a high morbidity and mortality rate (60-80%), due significantly to failure of timely diagnosis.

Currently there is no blood, urine or radiological test that provides a definitive AMI diagnosis or predicts successful surgical resolution. Conventional biochemical markers of […]

Solar Powered Oxygen Delivery

Description

Researchers at the University of Alberta and Jinja Regional Referral Hospital, Uganda have developed a novel system to deliver oxygen in remote and resourcelimited hospitals that have minimal access to oxygen cylinders or an electric power supply. A pilot system has been tested and implemented in hospitals in Uganda for treating children under the age […]

Plasma Protein Biomarkers for Fabry Disease

Description

Researchers at the University of Alberta have discovered novel plasma protein biomarkers in Fabry patients which can be used to develop diagnostic kits for patients with ambiguous mutations or non-specific symptoms. In addition, these biomarkers can also be used as prognostic markers for Fabry disease. Another application of these novel biomarkers can be in better […]
