Device for Closure of Transvascular or Transcameral Access Ports

This technology includes part of transcatheter aortic valve replacement and to enable non-surgical thoracic aortic aneurysm endograft repair. The invention enables a completely new way to access the arterial circulation to allow introduction of large devices, such as transcatheter aortic valve replacement, percutaneous left ventricular assist devices, and thoracic aortic endografts. It also can be used in most labeled and off-label applications of Amplatzer (AGA Medical, St Jude) nitinol occluder devices to occlude intracardiac holes and to allow non-surgical direct access to the heart.

Systems and Methods for Applying Pressure to the Heart for the Treatment of Tricuspid Valve Regurgitation

This technology includes structures and methods for cinching a band around the heart for treating conditions including tricuspid valve regurgitation (TR). When positioned appropriately along the atrioventricular groove, the band is tightened around the heart which narrows the tricuspid annulus and relieves TR.

Helical Guidewires and Related Systems for Transcatheter Heart Valve Procedures

This technology includes a guidewire purpose-built for delivery of bulky transcatheter heart valves (THV). Conventional THV guidewires are rigid and have a distal tip shaped like a pigtail to prevent apical ventricular perforation. This invention is a 3-dimensional helical or antihelical curve that can protect against apical perforation, possibly better, and that allows subtle 3-mensional deflection to aid the operator in achieving coaxiality or overcoming delivery obstacles such as calcific spicules.

Device for Closure of Transvascular or Transcameral Access Ports

This technology includes a novel method to access the arterial circulation to allow introduction of large devices, such as transcatheter aortic valve replacement, percutaneous left ventricular assist devices, and thoracic aortic endografts. It also can be used in most labeled and off-label applications of Amplatzer nitinol occluder devices to occlude intracardiac holes and to allow non-surgical direct access to the heart. This new disclosure adds additional design features that have been tested in vivo.

Phase Sensitive Motion Correction and T1 Mapping for Cardiovascular Magnetic Resonance Imaging

This technology includes a method of correcting the motion during T1 mapping using cardiovascular magnetic resonance imaging (MRI). Ischemic heart disease is the leading cause of death in the United States. The lack of blood supply among myocardial tissue, especially for scar regions, changes the T1 relaxation value of heart muscles. The non-invasive quantification of T1 value of myocardium (T1 mapping) is therefore of great importance for the diagnosis and treatment of cardiovascular disease.

An Automated System for Myocardial Perfusion Mapping and Machine Diagnosis to Detect Ischemic Heart Disease with First-pass Perfusion Cardiac Magnetic Resonance Imaging

This technology includes a fully automated computer aided diagnosis system to quantify myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) pixel maps from the first-pass contrast-enhanced cardiac magnetic resonance (CMR) perfusion images. This system performs automated image registration, motion compensation, segmentation, and modeling to extract quantitative features from different myocardial regions of interest.

Transcatheter MRI-guided Implantable Cavopulmonary Bypass Endograft for the Treatment of Congenital Heart Disease

This technology includes a catheter-delivered endograft designed to treat congenital heart disease without surgery. The specific surgical procedure averted is cavopulmonary bypass graft. The key innovations are features to effect distal end-to-side anastomosis and proximal end-to-end anastomosis without surgery. The system operates under X-ray and MRI guidance.

Immunoassay-derived Protein Biomarkers of Atherosclerotic Cardiovascular Disease Risk

This technology includes a combination of 6 protein biomarkers and clinical risk factors to be used as an In Vitro Diagnostic Multivariate Index Assay (IVDMIA) that can improve the identification of individuals at high risk for atherosclerotic cardiovascular disease (ASCVD). Incorporation of novel protein biomarkers of ASCVD risk into risk assessment algorithms may improve their ability to identify individuals at high risk for ASCVD.

Mass Spectrometry Derived Protein Biomarkers of Atherosclerotic Cardiovascular Disease Risk

This technology includes a combination of protein biomarkers and clinical risk factors to be used as an In Vitro Diagnostic Multivariate Index Assay (IVDMIA) that can improve the identification of individuals at high risk for atherosclerotic cardiovascular disease (ASCVD) and myocardial infarction (MI). Incorporation of novel protein biomarkers of ASCVD risk into risk assessment algorithms may improve their ability to identify individuals at high risk for ASCVD.

PET Imaging of lntegrin Expression with Suitably Labeled RGD Peptides for Multiple Diagnostic Purposes

This technology includes a number of dimeric RGD peptides which been developed and labeled with various PET isotopes (1BF, 68Ga, and 64Cu) for imaging integrin expression in cancer, inflammation, rheumatoid arthritis, myocardial infarct, stroke and traumatic injury. A number of these peptides have been translated into clinic for diagnosis and therapy response monitoring.
