A method for direct therapeutic treatment of myocardial tissue in a localized region of a heart having a pathological condition. The method includes identifying a target region of the myocardium and applying material directly and substantially only to at least a portion of the myocardial tissue of the target region. The material applied results in a physically modification the mechanical properties, including stiffness, of said tissue. Various devices and modes of practicing the method are disclosed for stiffening, restraining and constraining myocardial tissue for the treatment of conditions including myocardial infarction or mitral valve regurgitation.

A dietary supplement blend composition is disclosed, the basic formulation of the composition containing vitamins, minerals, and carotenoids. The composition can also contain bioflavonoids, cartilage protectors such as glucosamine or chondroitin, alpha-lipoic acid, coenzyme Q10, and a source of omega-3 fatty acids such as flax seed oil. The composition is beneficial for improving health and preventing disease, particularly for degenerative conditions. A method for supplementing the diet is also disclosed, wherein the quantity of daily rations of the dietary supplement blend composition is determined based on the person's age, body weight, and quality of diet.

A splint assembly for placement transverse a heart chamber to reduce the heart chamber radius and improve cardiac function has a tension member formed of a braided cable with a covering. A fixed anchor assembly is attached to one end of the tension member and a leader for penetrating a heart wall and guiding the tension member through the heart is attached to the other end. An adjustable anchor assembly can be secured onto the tension member opposite to the side on which the fixed pad assembly is attached. The adjustable anchor assembly can be positioned along the tension member so as to adjust the length of the tension member extending between the fixed and adjustable anchor assemblies. The pad assemblies engage with the outside of the heart wall to hold the tension member in place transverse the heart chamber. A probe and marker delivery device is used to identify locations on the heart wall to place the splint assembly such that it will not interfere with internal heart structures. The device delivers a marker to these locations on the heart wall for both visual and tactile identification during implantation of the splint assembly in the heart.

A device for regulating blood pressure between a patient's left atrium and right atrium comprises an hourglass-shaped stent comprising a neck region and first and second flared end regions, the neck region disposed between the first and second end regions and configured to engage the fossa ovalis of the patient's atrial septum; and a one-way tissue valve coupled to the first flared end region and configured to shunt blood from the left atrium to the right atrium when blood pressure in the left atrium exceeds blood pressure in the right atrium. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies.

This invention relates to devices and methods for the therapeutic changing of the geometry of the left ventricle of the human heart. Specifically, the invention relates to the apical introduction of an anchoring device to align the papillary muscles.

The present invention relates to traditional Chinese medicine for treating coronary heart disease and stenocardia is made from (by wt.%) salvia root 50-97%, notoginseng 2-48% and borneol 0.2-3%, in which the salvia root and notoginseng and hot extracted with water, then filtering, concentrating, alcohol precipitating, standing still, recovering ethyl alcohol, concentrating, into extractum, further blended with borneol and adjuvant polyglycol-6000 to form into product.

The inventive device may include a biodegradable material that biodegrades to offset flow changes caused by tissue ingrowth. The inventive device may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits.

The surgical implantation of a link, which may be in the form of a tether or a looped band, is proposed to connect and reduce the spacing between papillary muscles, to reduce dilation of the left ventricle. The implanted link thus improves heart function by reducing left ventricular failure.

A method of placing a pacing lead in the heart includes moving an electrode catheter successively to a plurality of possible placement sites. The viability of the tissue at each site is determined. If the tissue at the site is viable, a pacing signal is applied to the tissue at the site, and the effectiveness of the pacing from the site is measured. After the area has been mapped in this fashion, at least one pacing lead is placed from at least one of the sites which exceeded a predetermined level of pacing effectiveness.

The surgical implantation of a link, which may be in the form of a tether or a looped band, is proposed to connect and reduce the spacing between facing walls of the left ventricle, to reduce dilation of the left ventricle. Decreasing the distance between the facing portions of the ventricle may also more appropriately align the chordal apparatus to decrease mitral regurgitation. The implanted link thus improves heart function by reducing left ventricular failure.

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band having an elongate and arcuate body. The elongate and arcuate body has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is displaced from the plane containing the first end and the second end. The transvalvular band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets and the central portion is displaced towards the left ventricle relative to the first anchoring portion and the second anchoring portion. The ventricular direction displacement moves coaption to an earlier point in the cardiac cycle.

The current invention is an intracardiac pressure guided pacemaker. It has a sensor in pacemaker lead to sense intracardiac pressure, which is used to find the best pacing location in the cardiac chamber and to adjust the timing of pacing signal. It will optimize pacing location and pacing timing and, therefore, optimize resychronization of the contraction of myocardium and interaction between different cardiac chambers. This will improve cardiac function at the same working condition without increase in oxygen demand from myocardium. The pacemaker has a computer program, which, based on intracardiac pressure, can adjust pacing parameters of the pacemaker to optimize resynchronization of the myocardium and interaction between different cardiac chambers automatically at different heart rate and in certain time interval specified by care provider. This also can be achieved by using an interrogator manually. The pacemaker can also store profiles of pacing parameter and intracardiac pressure, which can be retrieved for review to help optimize cardiac performance.
