Patents by Inventor Ram Kumar Balachandran

Ram Kumar Balachandran has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11160647
    Abstract: Described are surgical implants that include releasable reinforcement, and related methods, particular example implants and methods being useful for treating pelvic tissue, cardiac tissue, and hernia, wherein the releasable reinforcement can be released (removed or disabled) during a surgical procedure to affect a mechanical property of the implant or a portion of the implant.
    Type: Grant
    Filed: April 17, 2017
    Date of Patent: November 2, 2021
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: Thomas A. Albrecht, Ram Kumar Balachandran, John A. Bostrom
  • Patent number: 10820978
    Abstract: The present invention relates to surgical implants with adjustable size features, and methods for treating pelvic conditions by use of the implants.

  • Patent number: 10716672
    Abstract: A system for determining the dimensions of a native valve annulus may include a sensing catheter, a transmitter, and a computing device. The sensing catheter may include a shaft extending in a longitudinal direction; a plurality of splines attached to the shaft, the splines having an expanded condition spaced radially outward from the shaft; and at least one sensing coil located on each of the splines. The transmitter may generate a magnetic field to induce a potential in each of the sensing coils, and the computing device may identify the positions of the sensing coils based on the induced potentials.

  • Patent number: 10582882
    Abstract: A system for detecting the dimensions and geometry of a native valve annulus for trans-catheter valve implantation includes a compliant balloon and a shaft within the balloon. One or more drive electrodes may be affixed to a surface of the balloon, and one or more sense electrodes may be affixed to the shaft. After insertion of the balloon into the native valve annulus, the drive electrodes may be energized with a predetermined voltage. Using a trained statistical model and the voltages measured at the sense electrodes, initial estimates of the cross-section of the valve annulus may be obtained. The initial estimates may then be provided to an optimization model of the valve annulus to obtain a highly accurate prediction of the cross-section of the valve annulus.
