  • Patent number: 8784479
    Abstract: A device for repairing a heart valve comprises an implantation instrument. The implantation instrument comprises a first support ring, and a second support ring connected to said first support ring to form a coiled configuration. The first support ring is configured to abut one side of the valve and the second support ring is configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween. The device further comprises an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly. The annuloplasty implant is connected to the implantation instrument for insertion to the annulus.

  • Publication number: 20140188215
    Abstract: The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing annuloplasty includes accessing a left ventricle of a heart to provide a discrete plication element to the left ventricle, and engaging the plication element to tissue near a mitral valve of the heart. Engaging the plication element includes causing the plication element to gather a portion of the tissue to create a plication. In one embodiment, accessing the left ventricle of the heart to provide the plication element includes accessing the left ventricle of the heart using a catheter arrangement.

  • Patent number: 8753266
    Abstract: A heart retractor links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the heart retractor of the present invention. The retractor includes a plurality of flexible arms and a plurality of rigid arms as well as a surgery target immobilizing element. One form of the retractor can be sued in minimally invasive surgery, while other forms of the retractor can accommodate variations in heart size and paracardial spacing.

  • Patent number: 8317695
    Abstract: A system for manipulating a heart during cardiac surgery permits coronary surgery on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system. A component of the system engages the heart with a heart positioning device, repositions the heart into a displaced position and maintains it in the displaced position while the heart continues to beat with substantially unabated and uninterrupted cardiac output. One form of the system can be used in minimally invasive surgery.

  • Patent number: RE44075
    Abstract: A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners and is self-contained whereby a fastener is delivered and placed all from inside a vessel. The fasteners are self-forming whereby they do not need an anvil to be formed. Anchor elements are operated from outside the patient's body to cinch a prosthesis to an anchoring cuff of the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. Fasteners are placed and formed whereby fasteners are located continuously throughout the entire circumference of the cuff.
