Abstract

The present invention concerns a variable stiffness catheter (1) for surgical applications, a system (2) and a method for manufacturing said catheter, wherein said catheter (1) comprises at least one soft biocompatible hollow sleeve (S) and further including: - a tip sealing cap (10) at a distal end, - a working channel (15) enclosed within said sleeve (S) and extending from a proximal end to said distal end, for applying a treatment outside the catheter (1), through said tip sealing cap (10), - a plurality of fibers (F) enclosed within said sleeve (S), - an inlet attachable to a source (SV) of vacuum or pressure for applying vacuum or pressure inside said sleeve (S), said fibers (F) being assembled in at least one bundle such that applying vacuum inside said sleeve (S) induces fiber jamming resulting in a stiffening from a soft state to a stiff state.

Radius (bone)

The radius or radial bone (PL: radii or radiuses) is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is longer than the radius, but the radius is thicker. The radius is a long bone, prism-shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch.

Humerus

The humerus (ˈhjuːmərəs; : humeri) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa).

Tibia

The tibia (ˈtɪbiə; : tibiae ˈtɪbii or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement.
