Research Summary:

Dr. Courtney develops new medical innovations, with a particular focus on imaging and therapeutic catheters for minimally invasive cardiovascular procedures. His current research projects include:

• Intracardiac echocardiography catheters and systems that provide 3D imaging of structures in the heart, Doppler capability, 4D imaging (3D + time) and anatomical reconstruction. This technology is being developed to guide a number of procedures such as trans-septal punctures during atrial fibrillation procedures, revascularization of peripheral or central venous occlusion, valve repairs and endovascular aneurysm repair.
• Hybrid intravascular ultrasound and optical coherence tomography imaging catheters and systems for producing high-resolution cross-sectional images of coronary arteries. This technology is being developed to assess the extent of coronary plaque, identify plaque composition, assist with stent deployment and resolve ambiguities in coronary angiograms.
• Custom medical devices for patients with unique cardiovascular anatomy who would otherwise go untreated.
• Preclinical validation of medical devices and cardiovascular procedures in animal models.
