  • Publication number: 20050218359
    Abstract: A valve, actuator and control system that allows minimizing the size of the actuator and operation of the control system in a manual mode that automatically prevents accidental operation by pipeline pressure is disclosed. The actuator uses gas pressure from the pipeline to power the actuator. In the event gas pressure is unavailable, a pair of manual hand pumps are incorporated to allow operation of the actuator and valve.

  • Publication number: 20040249408
    Abstract: Embodiments disclose a method for repairing a heart of a human. A method may include introducing a collapsed reinforcing element through the skin into the vascular system of the human. The method may include delivering the reinforcing element into a left ventricle through the arteries. Once inside the left ventricle, the reinforcing element may be expanded to an expanded shape. In certain embodiments, a reinforcing element may be used to structurally reinforce a portion of an endocardial surface of a heart. The reinforcing element may include a preshaped patch and/or a plurality of preshaped flexible conduits. The method may include deploying the reinforcing element soon after a myocardial infarction to inhibit naturally occurring remodeling of the heart. The reinforcing element may be deployed with or without the use of a shaper. In some embodiments, a reinforcing element may include an externally positioned apparatus configured to substantially reshape a portion of an interior chamber of a heart.

  • Patent number: 6740029
    Abstract: Disclosed is a device for isolating a cardiac surgical site. The device comprises a first finger having a clinging accessory for attaching the first finger to a heart, a second finger having a clinging accessory for attaching the second finger to the heart, a first joint disposed on the first finger so that the first finger may rotate on a surface of the heart such that said rotation stretches a surgical site, a first stopper disposed on the first finger for preventing undesired rotation of the first finger to isolate the surgical site, and a link for coupling the first finger to the second finger. Several embodiments of the fingers and clinging accessories are disclosed. A guard is provided to protect sutures from the clinging accessory. The guard is equipped with a sprayer to wash the surgical site. Also disclosed is a method of isolating a cardiac surgical site.
