  • Publication number: 20190117044
    Abstract: A direct visualization catheter includes a handle, a balloon, an elongate shaft, and a camera assembly. The elongate shaft has a proximal end and a distal end opposite the proximal end. The proximal end is coupled to the handle. The distal end is coupled to the balloon and defines a longitudinal axis. The camera assembly is coupled to the distal end of the elongate shaft and is disposed within the balloon. The camera assembly includes a camera and an adjustment mechanism for varying a configuration of the camera relative to the distal end of the elongate shaft between a delivery configuration and a deployed configuration. The camera faces primarily in a radial direction in the delivery configuration and the camera faces primarily in an axial direction in the deployed configuration.

  • Patent number: 9327113
    Abstract: Various embodiments concern a lead having a proximal section and a curbed section. The lead can comprise an outer tubular portion having a bias such that the lead assumes a curved shape along the curved section. The lead can further include an inner tubular portion extending within the outer tubular portion, the inner tubular portion comprising an inner coil conductor and an inner polymer jacket over the inner coil conductor along the curved section, the inner tubular member stiffer along the proximal section than the curved section, the outer tubular portion stiffer along the curved section relative to the inner tubular portion along the curved section such that the inner tubular portion can rotate relative to the outer tubular portion while the curved shape is substantially maintained. Relative rotation can extend and rotate and active fixation element.
