Abstract:
1. A method for extracting a tubular structure from tissue using a device including a handle having an actuator, an elongate body with a first end coupled to and extending from the handle, and an operational head coupled with the elongate body and disposed at a second end thereof, wherein the operational head further comprises a radially expandable and collapsible snare, configured to grasp the tubular structure when the snare is collapsed, the method comprising: inserting the elongate body into the tubular structure with the snare in a collapsed position; placing the snare into an expanded position by operating the actuator; surrounding the tubular structure with the expanded snare by operating the actuator; grasping a portion of the tubular structure with the snare by operating the actuator to collapse the snare on the tubular structure; and pulling the tubular structure from the tissue by moving the snare relative to the tissue and inverting the tubular structure upon itself with the collapsed snare and extracting the tubular structure from the tissue.
