This technology includes the determination of temperature dependent temporal deviations of the real from the intended gradient waveforms and k-space trajectories during MRI image acquisition, and the use of appropriate temperature dependent pre-compensations to avoid or reduce the image distortion caused by these temporal deviations on the gradient waveforms and k-space trajectories, which will improve imaging quality.

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.

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.

This technology includes a strategy for retrieving a pair of implanted magnets from a patient’s body. This method includes maneuvering a guide catheter with a guide magnet on the distal end. Current methods are geared toward magnetic compression occurring in the digestive system, while this method can be used as a less invasive method for cardiac magnetic compression.

This technology includes a novel cardiac patch which was 3D printed to repair damaged cardiac tissue. Based on biological and anatomical understanding of myocardial tissue, a novel 3D bioprinting technique was developed to directly fabricate the cellularized and vascularized cardiac patch with anisotropic fiber and perfusable vessel architecture. The design will integrate biomimetic aligned myocardial fibers and perfusable blood vessels to create a thick, functional cardiac patch, suitable for the human heart implantation.

This technology includes a pair of subsystems for a novel transcatheter bicuspid valve (frame and leaflets) intended for implantation in the mitral position. It is simple, it overcomes key limitations to transcatheter bicuspid mitral valve implants, and it overcomes key limitations to transcatheter tricuspid mitral valve implants.

This technology includes the use of nanodiamonds to achieve background-free imaging. We present several techniques to reduce or eliminate background florescence by exploiting properties of the fluorescent nanodiamonds. In particular, magnetic field modulation of the fluorescence intensity offers a simple, robust, and easily adaptable method to obtain background free imaging in a variety of imaging modalities, i.e., fluorescence microscopy and wide field fluorescence animal imaging.

This technology includes a new class of nanoparticles in the carbon family, fluorescent nanodiamonds (FNDs), exhibiting superb physical and chemical properties for diagnostic imaging applications. We have developed a simple, fast, and robust method to encapsulate FNDs in polydopamine that can be further functionalized. By integrating anatomical and molecular based imaging capabilities, multimodal nanoparticle probes are becoming important in the paradigm shift from conventional to future imaging technologies.

This technology includes design enhancements to transcatheter mitral cerclage annuloplasty. They include a device to convert from crossing guidewire to tension element, refinements to the tension element which incorporates a coronary artery protection device, a target/capture/snare device, a wishbone locking device, and a cutting device.

This technology includes a family of transcatheter endovenous intramyocardial tether (MIRTH) procedures to impose myocardial constraint on the LV (MIRTH), LV and RV (SCIMITAR), and cardiac resynchronization procedures. Included is a set of advanced cardiac treatment technologies that focus on minimally invasive procedures for heart patients. The main technology is the transcatheter endovenous intramyocardial tether (MIRTH) procedure, which is designed to apply physical constraint to the left ventricle (LV) of the heart.
