  • Patent number: 10624751
    Abstract: Knee prosthesis includes a femoral component adapted to fit on a distal end of the femur and a tibial insert component. The femoral component includes a measured anterior/posterior dimension defined by the posterior condyle surface and the interior surface of the anterior flange and a distal peg provided on a distal bone facing surface of each of the lateral and medial condylar structures, wherein the distal pegs are positioned at a midpoint of the measured anterior/posterior dimension. The implant system provides two distinct sizing segments and the tibial insert has a medial tibial aspect ratio of 0.74 and a lateral tibial aspect ratio of 0.65 to 0.68 for all sizes.

  • Publication number: 20190357858
    Abstract: A method for controlling an orientation of a steerable distal portion of an elongate instrument, said instrument comprising at least one tensioning member attached to said steerable distal portion may include receiving an input command at a controller for articulation of said steerable distal portion, the articulation correlating to an approximate y-bend and an approximate x-bend of said steerable distal portion; calculating an approximate overall bend from said approximate y-bend and said approximate x-bend; and setting a limit of said approximate overall bend beyond which said steerable distal portion is not permitted to achieve. The method may further include one of: causing actuation of said at least one tensioning member to achieve said y-bend and said x-bend on a condition of said calculated approximate overall bend being equal to or less than said limit, and repeating the receiving, calculating, and setting steps on a condition of said calculated approximate overall bend being greater than said limit.

  • Patent number: 10426412
    Abstract: The present invention relates, generally, to reporting the approximate three-dimensional orientation of the steerable distal portion of an endoscope to the user of the endoscope. More particularly, the present invention relates to a system and method for providing the endoscope-user a display from which to more easily determine the approximate three-dimensional orientation of the steerable distal portion of the endoscope, thereby facilitating navigation of the endoscope. The present invention also relates to a system and method for limiting the amount the steerable distal portion can bend overall to reduce or eliminate the user's ability to over-retroflex the steerable distal portion of the endoscope.

  • Patent number: 9357901
    Abstract: A system for graphically visualizing an orientation of a steerable distal portion of an elongate instrument is disclosed. The system includes an instrument having an elongate body. The elongate body includes a proximal portion and a steerable distal portion. The system also includes at least one tensioning member attached to said steerable distal portion, wherein the actuation of said at least one tensioning member results in an approximate y-bend and an approximate x-bend of said steerable distal portion, and wherein said approximate y-bend and approximate x-bend define an approximate overall bend of said steerable distal portion. The system further includes a graphical user interface and an icon representing said approximate overall bend on said graphical user interface.
