31 results about "Aneurysm formation" patented technology

Aneurysm formation is due to multiple factors affecting the arterial segment and its local environment. Many aneurysms are atherosclerotic in nature. As the aneurysmal dilatation increases, the arterial wall tension also increases and this can result in rupture of the aneurysm.

Elastin stabilization of connective tissue

A method and product are provided for the treatment of connective tissue weakened due to destruction of tissue architecture, and in particular due to elastin degradation. The treatment agents employ certain unique properties of phenolic compounds to develop a protocol for reducing elastin degradation, such as that occurring during aneurysm formation in vasculature. According to the invention, elastin can be stabilized in vivo and destruction of connective tissue, such as that leading to life-threatening aneurysms in vasculature, can be tempered or halted all together. The treatment agents can be delivered or administered acutely or chronically according to various delivery methods, including sustained release methods incorporating perivascular or endovascular patches, use of microsphere carriers, hydrogels, or osmotic pumps.

Intramyocardial patterning for global cardiac resizing and reshaping

ActiveUS20080065048A1Thickening myocardiumReducing systolic volumeInfusion syringesHeart valvesVentricular dysrhythmiaCardiac wall
Cardiomyopathy may be treated by distributing space-occupying agent within the myocardium in a pattern about one or more chambers of the heart, such that the space-modifying agent integrates into and thickens at least part of the cardiac wall about the chamber so as globally to reduce wall stress and stabilize or even reduce chamber size. Some patterns also cause a beneficial global reshaping of the chamber. These changes occur quickly and are sustainable, and have a rapid and sustainable therapeutic effect on cardiac function. Over time the relief of wall stress reduces oxygen consumption and promotes healing. Moreover, various long-term therapeutic effects may be realized depending on the properties of the space-occupying agent, including combinations with other therapeutic materials. Specific cardiac conditions treatable by these systems and methods include, for example, dilated cardiomyopathy (with or without overt aneurismal formations), congestive heart failure, and ventricular arrhythmias. Patterns of distribution of space-occupying agent within the myocardium for global resizing may also be used or augmented to treat localized conditions such as myocardial infarctions, overt aneurysm of the ventricular wall as typically forms in response to large transmural myocardial infarctions, and mitral regurgitation due to a noncompliant mitral valve. These techniques may also be used to treat localized conditions that may not yet have progressed to cardiomyopathy.

Apparatus for vessel characterization

The invention discloses an apparatus (2), a system (1) and a method (100) for characterization of vessels and for vessel modeling. The cross sectional area (A1) of the vessel is derived from pressure measurements (p1, p2) obtained by an instrument (3) from within the vessel. When multiple cross sectional areas (A1, A2) are derived for multiple reference positions (r1, r2) based on pressure measurements (p1, p2, p3) along the vessel, a representation (20, 30) of the vessel can be rendered, without requiring any imaging modality. Furthermore, the effect of the pulsatile blood flow on the elasticity of the vessel walls can be visualized, supporting assessment of a stenosis or an aneurysm formation along the vessel.

Treatment of aneurysms

ActiveUS20200138810A1Effective biomarkerReduce mortalityOrganic active ingredientsCardiovascular disorderKynureninaseMetabolite
The present invention provides methods for detecting and / or treating a subject having an aneurysm or at risk for developing an aneurysm. It has been discovered that a key metabolite of the kynurenine (Kyn) pathway, a major route for the metabolism of essential amino acid tryptophan (Trp) into nicotinamide adenine dinucleotide (NAD+), plays a critical role in the formation of aneurysms, for example abdominal aortic aneurysms. In particular, it has been discovered that 3-Hydroxyanthranilic acid (3-HAA), a product of kynureninase (KYNU), plays a causative role in the formation of aneurysms by, for example exerting pro-inflammatory effects on vascular smooth muscle cells. It has further been discovered that elevated levels of 3-HAA are indicative of the presence and / or progression of an aneurysm, and 3-HAA levels correlate with the size (aortic diameter) of the aneurysm.
