    摘要: Methods and devices for passively assisting the cardiac function of the heart are disclosed. A method of increasing the cardiac output of a heart includes providing a site of surgical access to the portion of the heart to be restrained, reducing the cardiac expansion of the portion of the heart to be restrained, and maintaining the reduction of cardiac expansion of the portion of the heart to be restrained for a substantial amount of time. Cardiac assist devices for increasing the cardiac output of the heart are disclosed comprising a reinforcing portion configured to contact a portion of the heart tissue wherein the reinforcing portion restricts the expansion of the portion of the heart tissue. The reinforcing portion can be a number of structures, including pads, frames, straps, and other retaining means for limiting cardiac expansion of the portion of the heart tissue to be restrained.

    摘要: The invention is devices and techniques which use a negative (suction) pressure or vacuum, applied through a surgical instrument, to fix the position of a portion of the surface of a beating heart so that a surgical procedure can be more easily performed. The devices apply a negative pressure at several points on the outer surface of the heart such that a portion of the heart is fixed in place by the suction imposed through the surgical instrument. Because the instrument fixes the position of the tissue, and because the instruments remain at a constant distance from the particular portion of the heart where the surgery is being performed, the device may also serve as a support or platform so that other surgical instruments or devices can be advantageously used at the site. In certain preferred embodiments, the devices described herein have structures to facilitate the use of additional surgical instruments such that the placement of negative pressure device permit the surgeon to advantageously manipulate the other instruments during surgery. The negative pressure is preferably imposed through a plurality of ports which may be disposed in a substantially planar surface of the instrument which contacts the cardiac tissue.

    摘要: The invention is an apparatus and method to perform a surgical procedure within the beating heart. The instrument provides a seal to surround cardiac tissue, thereby defining a segregated surgical field within the body of the instrument. A suction device is preferred to remove blood and fluids from the surgical field so that a surgical procedure can be performed while the heart continues to beat. The instrument is particularly suitable for a procedure to repair defective or diseased cardiac valves, such as the mitral valve; a procedure which previously required that the heart be stopped so that the corrective surgical procedure could be performed.
