摘要： The present invention may provide devices suitable for insertion into a body passage. The devices may include a conduit and a distal head region located at the distal end of said conduit. A plurality of apertures on the surface of said head region and conduit may be used to direct a liquid spray outwards from said device. The apertures may be designed and spatially arranged such that when the device is inserted into a body passage, the liquid spray emitted from said apertures may be capable of both reducing the frictional contact between the device and the walls of said passage and of cleansing said passage of undesired solid and other particulate matter.

摘要： A method and device featuring at least one component providing a potential to kinetic converted elastic, magnetic repulsion, or, an elastic and magnetic repulsion, pushing, pulling, or, pulling and pushing, type of radially outward expansive force or pressure to an inner, outer, intermediate, and, combination thereof, wall region of the left ventricle, for reducing intraluminal hydrostatic pressure of the left ventricle (LV filling pressure) during the ventricular diastolic stage of the cardiac cycle, thereby, improving diastolic function of the left ventricle of the heart in subjects having a condition of diastolic heart failure (DHF), while minimally disturbing systolic function of the heart. The expansive force or pressure is in a range of about 5-40 mm Hg, whereby, left ventricular end diastolic pressure (LVEDP) is reduced down to the normal range of about 6-12 mm Hg, during ventricular diastole of the heart.
