Device for Non-Surgical Tricuspid Valve Annuloplasty

This is a non-surgical tricuspid annuloplasty to treat functional tricuspid valve regurgitation, meaning regurgitation with intact valve leaflets. The device is delivered using novel catheter techniques into the pericardial space and positioned along the atrioventricular groove. A compression member is positioned along the tricuspid annular free wall and tension applied through a variably-applied tension element. In the best embodiment, the compression member has an M shaped portion with at least two inflection points between the segments of difference curvatures.

MRI Scanner Bore Covering

This invention pertains to a bore covering for creating controlled environments and specifically for maintaining temperature within the bore of an MRI scanner. The bore covering includes a covering sheet with fastening means (e.g., weak-tack adhesive, pressure-sensitive adhesive or low-tack adhesive) around its inner surfaces that permits reversible attachment to the scanner. The adhesive ends can be peeled away to expose an edge of the bore opening or the entire sheet may be constructed with peel away gaps so that warm air can be pumped into the bore.

Aortic Access from Vena Cava for Large Caliber Transcatheter Cardiovascular Interventions

The invention pertains to a device and method for transcatheter correction of cardiovascular abnormalities, such as the delivery of prosthetic valves to the heart. Featured is a device implant for closing a caval-aortic iatrogenic fistula created by the introduction of a transcatheter device from the inferior vena cava into the abdominal aorta. The occlusion device includes an expandable transvascular implant with an elastomeric surface capable of extending between a vein and artery which conforms to the boundaries of an arteriovenous fistula tract between the artery and vein.

Device for Vascular Dilation

The invention is an enhanced vascular dilator that eliminates the vascular injury caused by the size mismatch between vascular introducer sheaths and vascular dilators, as the two are advanced into a blood vessel. The invention provides a “shoulder” to match the diameter of the introducer sheath so that there is a smooth transition, without size mismatch, between the dilator and the introducer sheath. The invention allows the dilator to be withdrawn in segments from the introducer sheath.

Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.

Real Time Medical Image Processing Using Cloud Computing

The invention pertains to a system for reconstructing images acquired from MR and CT scanners in a robust Gadgetron based cloud computing system. A hardware interface connects clinical imaging instruments (e.g., MR or CT scanners) with a cloud computing environment that includes image data reconstruction and processing software not limited by the computational constraints typical of static hardware with finite processor power.

Treatment of Chronic Kidney Disease with Synthetic Amphipathic Peptides

The invention is directed to treatment of chronic kidney disease by administering a synthetic, amphipathic helical peptide known as 5A-37pA, and novel derivatives thereof. Scientists at NIDDK have demonstrated that invention peptides antagonize activity of a particular scavenger receptor known as CD36. Using an in vivo model, NIDDK scientists have shown that invention peptides slowed progression of chronic kidney disease and can potentially be utilized as a therapeutic treatment.

A Novel Demodulation System in X-ray Imaging

In various x-ray imaging methods, including scattering correction and phase contrast imaging, intensity modulation in space is introduced into the projection images by the use of masks, gratings, or apertures. The present invention relates to a process to demodulate the modulation. The current demodulation processes are either to remove the modulation pattern through digital processing or to move the modulation pattern on the detector in a series of images that requires mechanical movements of a component and tends to lose some information of the imaged object.

A Novel X-ray Grating to Enhance Phase Contrast Imaging

The present invention relates to improving x-ray phase contrast imaging. The invention discloses a novel grating interferometer for phase contrast imaging with hard x-rays that overcomes limitations in the level of sensitivity by utilizing the advantages of far-field interferometers. The novel design and fabrication process can easily acquire absolute and differential phase images of lightly absorbing samples.
