  • Patent number: 9770554
    Abstract: A microplegia console for controlling the delivery of cardioplegia to a patient, comprising an integrated display/touch screen for displaying cardioplegia information and patient information and allowing inputting of parameters via the display/touch screen into the console for computer-controlled perfusion of cardioplegia into the patient. The invention further comprises a method for delivery of cardioplegia to a patient, including defining and selecting a protocol from a displayed list and sequencing a series of the protocols. The invention also comprises a method for cardioplegia delivery to achieve aortic valve closure. Additionally, the invention comprises a method for activating an icon whereby, upon a first selection of the icon, displaying an indicia indicating that the icon has been first selected; and upon a second selection of the icon, activating the icon.

  • Publication number: 20090088728
    Abstract: The present invention is directed towards a malleable sleeve used in conjunction with a multi-lumen catheter with an expandable device, such as a balloon, incorporated into its surface. The malleable sleeve allows the catheter to be pre-formed into a shape that corresponds with the shape of the nasal passageway. The present invention also covers endoscopic surgical methods utilizing the malleable sleeve.

  • Publication number: 20090076446
    Abstract: The improved balloon catheter includes a first tubular segment, which has multiple zones of differing malleability along its length. The catheter further includes a coaxially aligned hypotube formed of a malleable material, which is positioned within the lumen of the first tubular segment and extends from the distal end of the first tubular segment. In one embodiment the hypotube runs the length of the first tubular segment; while in another embodiment, the hypotube runs along only a portion of the length of the first tubular segment. A portion of the outer circumferential surface of the hypotube is permanently affixed and sealed to an inner circumferential surface of the first tubular segment in the vicinity of the distal end of the first tubular segment. The outer circumference of the distal end of the first tubular segment is gently tapered along its length so as to smoothly transition to the circumference of the hypotube.
