This inventions relates to compounds having the structure Formula I and pharmaceutically acceptable salts thereof which are soluble guanylate cyclase activators. The compounds are useful for treatment or prevention of cardiovascular diseases, endothelial dysfunction, diastolic dysfunction, atherosclerosis, hypertension, pulmonary hypertension, angina pectoris, thromboses, restenosis, myocardial infarction, strokes, cardiac insufficiency, pulmonary hypertonia, erectile dysfunction, asthma bronchiale, chronic kidney insufficiency, diabetes, or cirrhosis of the liver.

A catheter introduces electrodes in a vein for a minimally invasive treatment of venous insufficiency by the application of energy to cause selective heating of the vein. The catheter is positioned within the vein to be treated, and the electrodes on the catheter are moved toward one side of the vein. RF energy is applied in a directional manner from the electrodes at the working end of the catheter to cause localized heating and corresponding shrinkage of the adjacent venous tissue, which may include commissures, leaflets and ostia. Fluoroscopy or ultrasound may be used to detect shrinkage of the vein. After treating one section of the vein, the catheter can be repositioned to place the electrodes to treat different sections of the vein until all desired venous valves are repaired and rendered functionally competent.

A monitoring system comprises sensors adapted to be worn by a user, and, a processor linked with the sensor. The processor receives sensor data and processes this data to determine user posture data including data indicative of vertical distance between level of the user's heart and ankle. Based on the posture data together with a value for degree of user chronic venous insufficiency and / or blood density, generate an estimate of user static venous pressure while the user is static, without calf muscle pump activity. The processor also processes the sensor data to determine if there is calf muscle pump activity, and generates an estimate of user active venous pressure according to the static venous pressure estimate, rate of calf muscle activity, and a value for degree of user chronic venous insufficiency. The processor may generate the venous pressure estimate in real time, and may control an NMES device accordingly.

The present invention is directed to methods and compositions that may be used in disrupting the association of smooth muscle cells with lymphatic endothelial cells and in correcting the valvular dysfunction in veins and lymphatic vessels. Such compositions are useful for therapeutic and prophylactic treatment of impaired lymphatic and venous function, particularly for the treatment of lymphedema distichiasis or chronic venous insufficiency.

A catheter delivers an electrode within a vein for a minimally invasive treatment of varicose veins and venous insufficiency using RF energy. The catheter is introduced into a patient and positioned within the section of the vein to be treated. The electrode radiates high frequency energy towards the vein, and the surrounding venous tissue becomes heated and begins to shrink. The catheter includes a controllable member for limiting the amount of shrinkage of the vein to the diameter of the member. The electrode remains active until there has been sufficient shrinkage of the vein. The extent of shrinkage of the vein may be detected by fluoroscopy. After treating one section of the vein, the catheter and the electrode can be repositioned intraluminally within the vein to treat different sections of the vein until all desired venous sections and valves are repaired and rendered functionally competent.

The invention relates to a dietary supplement consisting of an aqueous extract of red vine leaves and an acceptable carrier which prevents and reduces the discomfort relating to mild-to-moderate chronic venous insufficiency of the legs.

The invention discloses a traditional Chinese medicine composition for improving renal functions and restraining renal fibrosis. Active pharmaceutical ingredients of the traditional Chinese medicine composition comprise, by weight, 10-15 parts of the root of red-rooted salvia, 10-60 parts of astragalus membranaceus, 10-30 parts of herba epimedii, 5-30 parts of sinensis and 3-30 parts of prepared rhubarb. Clinical researches show that 168 patients with chronic renal insufficiency are treated by the traditional Chinese medicine composition, a remarkable clinical effect is obtained, clinical symptoms are reduced, the clinical symptoms of some patients are basically eliminated, the renal functions of the patients can be remarkably improved, blood urea nitrogen (BUN) and creatinine (Scr) are obviously reduced, and total effective rate achieves 88.66%. Animal researches show that the traditional Chinese medicine composition can delay development of chronic renal failure, and the mechanism of the traditional Chinese medicine composition is relative to effects of effectively restraining precipitation of renal tissue collagen and secretion of TGF (transforming growth factor)-beta, accordingly restraining renal fibrosis, and the like. The traditional Chinese medicine composition is low in clinical application cost and excellent in curative effect, and is safe and reliable.
