    摘要： An intraventricular apparatus includes an elongated body having a substantially tubular sidewall that extends substantially axially between spaced apart first and second ends, an opening located proximal the first end. A valve is located adjacent the first end to provide for substantially unidirectional flow of blood therethrough. At least one aperture extends through the tubular sidewall at an axial location between the valve and the second end to provide for substantially free flow of blood between an interior and an exterior of the sidewall.

    摘要： The present invention may be characterized as a heart access manifold having a manifold wall and at least one exit port and one entry port. The exit port through the manifold wall is adapted to be sealably engaged about an opening in the wall of a heart for communication with the interior of the heart and with the interior of the manifold to be under the same pressure as the interior of the heart. At least one entry port is provided through the manifold wall to provide access through the manifold wall into the interior heart via the exit port. Each entry port is sealable to maintain pressure on an interior side of the manifold wall. The entry port is adapted for passage therethrough to the interior side of the manifold wall of at least one implement in sealed relation so as to maintain pressure on the interior side of the manifold. The implement may be one which is selected to perform any operation that is desired or necessary within the interiors of the manifold or the heart. Suitable implements include microwave or ultrasonic probes, knives, cutters, staplers, holders, clamps, suturing devices, lasers and the like which are useful for carrying out procedures within the interior of the heart.

    摘要： Diagnostic and surgical procedures may be performed on a beating heart using an assembly which includes a port and a fluid transport device. The port has a housing for insertion through a wall of the heart chamber and may include one valve disposed in the housing and an inlet connected to the housing. Methods for repair and diagnosis of the heart are also described. A specific method for repairing a mitral valve uses staples which may be banded together with a strip of material.

    摘要： The present invention provides apparatuses and methods for performing minimally invasive diagnostic and surgical procedures inside of a beating heart. An assembly for use in performing such a medical procedure includes a port and a fluid transport device. The port has a housing configured for insertion through a chamber wall of a heart chamber, at least one valve disposed in the housing, and an inlet connected to the housing. The inlet has an inlet passage in fluid communication with a lumen of the housing. The fluid transport device has an end that attaches to the inlet of the port, another end that attaches to a fluid source, and a fluid channel therebetween to pass a fluid from the fluid source to the heart chamber. A method of preparing a beating heart for a diagnostic or medical procedure comprises the steps of inserting a cardiac port through a chamber wall of the beating heart and pressurizing the heart chamber with blood from the patient's artery. Repair of the heart's mitral valve can be effected by a stapled annuloplasty procedure. Where sutures are used in the diagnostic or surgical procedure, a suture cutting device for cutting a suture inside a beating heart can be used. The suture cutting device can include an elongated body having a lumen, a wall member extending into the lumen, and a knot-receiving chamber defined by a first area on a first side of the wall member. The wall member defines a channel therethrough dimensioned to permit passage of a suture and to prevent passage of a knot. A cutting implement is movably disposed in the lumen in a second area on a second side of the wall member opposite the first side. The cutting implement moves between a first position and second position to cut the suture. Movement of the cutting implement is limited to ensure that the cutting implement does not cut through the suture knot.
