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.

Methods to Produce Very Long Chain Fatty Acids (VLCFA) for Use as Nutritional Formulas and as Therapeutics for Disease

This technology includes a new method to prepare very long chain fatty acids (VLCFA), which does not use the previously reported toxic mercury amalgam, for use as nutritional supplements, and as therapeutics for various diseases. The key coupling step involves an organocopper mediated coupling of the Grignard regent derived from the bromo alkyl tetraene with a bromoalkyl containing a protected alcohol. After the coupling the alcohol Is deprotected and oxidized to prepare the very long fatty acid. The synthetic approach is flexible and can be used to prepare the other VLCFA compounds.

LZK and DLK Inhibitors to Target LZK and Suppress MYC Expression, Inhibit AKT Activation, and Promote Cancer Cell Death and Tumor Regression

This technology includes the use of LZK and DLK inhibitors to be used for the treatment of head and neck squamous cell carcinoma (HNSCC) or lung squamous cell carcinoma (LSCC). Specifically, we demonstrate that inhibitors that can be repurposed to target LZK suppresses LZK kinase-dependent stabilization of MYC and activation of the PI3K/AKT pathway. In vivo preclinical cell line xenograft mouse model demonstrates that targeting LZK will suppress tumor growth. We also demonstrate that several additional compounds potently inhibit LZK and could serve as new therapeutic modalities.

Devices and Methods for Cerclage of Luminal Systems

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.

Expanded Claims for Transcatheter Coronary Sinus Mitral Valve Annuloplasty Procedure and Coronary Artery and Myocardial Protection

This technology includes a novel transcatheter repair for functional mitral valve regurgitation, called mitral cerclage annuloplasty. This includes coronary artery protection for mitral cerclage annuloplasty against inside-out compression from subsequent transcatheter valve-in-ring mitral valve implantation, wherein the ring is created by the cerclage annuloplasty. Cerclage annuloplasty is to create a semi-rigid ring at the level of the mitral annulus.

Segmented Metallic MRI Guidewires Using Stiffness-matched Nonconductive Connectors for Catheterization Procedures

This technology includes a metallic guidewire that is suitable for MRI catheterization, because it is mechanically long but electrically consists of short conductive segments that cannot resonate during MRI. The invention consists of stiffness-matched non-conductive connectors or connections that are used along with short metallic segments. The embodiment reduced to practice has torquability and flexibility comparable to marketed metallic guidewires, yet is free from MRI heating.

Generalized MRI Artifact Reduction Using Array Processing Method

The invention is a phased array combining method for reducing artifacts in Magnetic Resonance (MR) imaging. The method uses a constrained optimization that optimizes signal-to-noise subject to the constraint of nulling ghost artifacts at known locations. The method is effective in reducing or canceling artifacts that arise in a wide variety of MR applications, including ghost artifacts from echo planar imaging and Gradient Recalled Echo with Echo Train (FGRE-ET) imaging used in cardiac or other rapid imaging applications.

Method and Apparatus to Improve an MRI Image

The invention is a method for improving image quality in MR imaging methods using the SENSE (SENSitivity Encoding) method, which is known to have degraded image quality due to numerical ill-conditioning (so called g-factor loss). The invention improves the numerical conditioning by means of an adaptive regularization (matrix conditioning), thereby improving image quality for a given scan time. This is accomplished by adaptively adjusting the regularization parameter for each pixel position to achieve a target ghost artifact suppression.
