  • Methods of manufacturing a catheter having a sensor
    Patent number: 10773053
    Abstract: A method of manufacturing a flexible catheter with a locatable sensor includes simultaneously rotating first and second spools about a common axis, whereby first and second leads of a wire twist together to form a twisted pair of the wire, and rotating a catheter body about a longitudinal axis defined by the catheter body, whereby the twisted pair of the wire wraps about a proximal end portion of the catheter body.
    Type: Grant
    Filed: January 24, 2018
    Date of Patent: September 15, 2020
    Assignee: COVIDIEN LP
    Inventors: Daniel A. Ranum, Brian T. Stolz, Nathan J. Knutson, David M. Costello
  • Methods of manufacturing a catheter having a sensor
    Patent number: 10773051
    Abstract: A method of manufacturing a flexible catheter with a locatable sensor includes non-rotatably coupling a spool with a wire to a first portion of a spool carrier, non-rotatably coupling the spool carrier to a catheter body, and rotating the spool carrier with the catheter body, thereby wrapping a portion of the wire about a distal end portion of the catheter body to form a wrapping layer.
