  • Patent number: 12616501
    Abstract: A surgical introducer system having an outer introducer sidewall extending along a longitudinal axis from a proximal introducer end to a distal introducer end, an inner introducer sidewall extending within the outer introducer sidewall along the longitudinal axis and forming an introducer passage extending in a distal direction from a proximal passage opening at the proximal introducer end to an introducer passage end wall located proximal to the distal introducer end, and an end wall passage extending from the introducer passage end wall towards the distal introducer end. The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction.

  • Publication number: 20250295431
    Abstract: Provided is an expandable surgical access port having an arm mounting body defining an opening surrounding a longitudinal axis, a number of primary arms arranged around the longitudinal axis, a number of secondary arms arranged around the longitudinal axis, an activation ring rotatably mounted to the arm mounting body to pivot the primary and secondary arms from a closed position to an opened position, and a an expandable membrane extending along the primary and secondary arms. When arms are in the opened position, the expandable membrane has an elongated membrane cross-section as viewed along the longitudinal axis.

  • Publication number: 20250064480
    Abstract: A surgical introducer system having an outer introducer sidewall extending along a longitudinal axis from a proximal introducer end to a distal introducer end, an inner introducer sidewall extending within the outer introducer sidewall along the longitudinal axis and forming an introducer passage extending in a distal direction from a proximal passage opening at the proximal introducer end to an introducer passage end wall located proximal to the distal introducer end, and an end wall passage extending from the introducer passage end wall towards the distal introducer end. The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction.

  • Patent number: 11517347
    Abstract: An introducer system for use with a navigation probe. The introducer system has an introducer and a probe retainer configured to selectively connect to the introducer. The probe retainer includes a receiver configured to receive a navigation probe shaft and limit movement of the navigation probe shaft in the lateral direction. A first clamp and a second clamp are connected to the receiver with the receiver located between the first clamp and the second clamp. Each of the first clamp and the second clamp is selectively engageable with respective portions of the introducer sidewall to hold the receiver at a fixed location relative to the introducer. The receiver, the first clamp, and the second clamp are configured to provide a visual path through the probe retainer and into the introducer passage.

  • Patent number: 11045182
    Abstract: A surgical introducer system having a sidewall that forms an introducer passage, and a probe receptacle at the distal end of the introducer. The probe receptacle begins at a proximal end and terminates at a distal end with the proximal receptacle end being between the distal receptacle end and the proximal introducer end. The receptacle's inner surface tapers continuously from the proximal end to the distal receptacle end, with the lateral size being greater at the proximal receptacle end. The inner surface receives the distal tip of a navigation probe and restricts movement of the distal probe tip in the lateral direction, and the sidewall is spaced from the navigation probe shaft to allow the shaft to move in the lateral direction within the passage when the distal probe tip is positioned in the probe receptacle.
