Patent ID: 11278704

Abstract:
Disclosed is a method for manufacturing a steerable instrument for endoscopic and/or invasive type applications, the instrument including an elongated tubular body having a proximal end part, a distal end part and an intermediate part between proximal and distal end parts, the proximal end part having at least one actuation proximal zone. The distal end part has at least one flexible distal zone, and the elongated tubular body is configured such that a movement of an actuation proximal zone is transferred to a corresponding flexible distal zone for a corresponding movement thereof. The elongated tubular body includes an inner, outer, and intermediate cylindrical elements having longitudinal elements between the inner and outer cylindrical elements. Inner, outer and intermediate cylindrical elements are coupled so movement of an actuation proximal zone is transferred by the longitudinal elements of one of the intermediate cylindrical elements to a corresponding flexible distal zone.
