A medical device for guiding through anatomy, such as a catheter or guidewire, with a tubular body that has been slotted to enhance bending flexibility, and a polymer liner with an anti-collapsing structure, and a method of making a medical device with a kink-resistant corrugated tubular member and an anti-collapsing structure. Anti collapsing structures may be helical or annular, and may be wire, such as ribbon wire, grooves in the liner, corrugations, or a braid. Liners may be bonded to the anti-collapsing structure, or may have two layers, with the anti-collapsing structure between the layers. Corrugations may be formed between sections of the anti-collapsing ‘structure with heat, pressure, stretching, compression, a mold, or a combination thereof, and may extend inward or outward. Shape or wall thickness may vary along the length to provide a varying bending stiffness. Slots may be formed in groups of two, three, or more, and adjacent groups may be rotated about the axis forming a helical pattern.

To provide an aircraft wing which has both high bending flexibility in the wing chord direction and high capacity to maintain the wing shape in the wing span direction, and to which morphing aircraft technology can be applied in the high-speed regime where aerodynamic forces are high. The wing is formed by arranging a plurality of CFRP rods having maximum anisotropic stiffness in the axial direction, so as to be parallel to the wing span direction, and filling the gaps between the CFRP rods with an elastic material.

A multi-joint endoscope bending mechanism with a force sensing function relates to an endoscope bending mechanism. In an existing medical endoscope, only one section at a head end of the endoscope is provided with bending controllability, the other parts of the endoscope do not have the function, and the surface of the endoscope is not integrated with a pressure sensor so that the contact pressure between a scope body and the intestinal canal wall can not be sensed. In the multi-joint endoscope bending mechanism, a first and a second connecting ear of a universal ring of two adjacent joints are matched and riveted with rivet clearances; a guide through hole of a guide seat on a universal ring of a start end joint of each bending uni-joint section is fixedly connected with a spring tube; four multi-strand steel wires in the bending uni-joint section pass through each spring tube and each guide through hole and are fixedly connected with a rear end circular ring; five bending uni-joint sections are wrapped by steel wire woven nets and rubber covering films from the inside to the outside; and pressure sensors are embedded in the rubber covering films. The multi-joint endoscope bending mechanism has a flexible spatial complexing bending capability and also a full-direction force sensing function. When used for examining an intestine problem of a patient, the multi-joint endoscope bending mechanism can relieve the pain suffered by the patient and is highly safe.

Laser beam machining is applied to form arbitrarily shaped electroactive ceramics for transducers (e.g., electromechanical sensors and actuators). One particularly preferred embodiment of the invention comprises machining parallel grooves in a ceramic plate to improve flexibility. The grooves provide strain relief in bending by relieving Poisson strains transverse to the direction of bending. This embodiment offers the further benefit that planar anisotropy or directionality is introduced in the transducer. The machining process of the invention further enables the production of more complex geometries than those currently known in the art. Because of the flexibility of the machining process, virtually any desired transducer shape may be produced.

A guidewire navigable through body vessels of a human subject for delivery of a catheter or the like is provided. The guidewire has a tube which receives a corewire that protrudes beyond a distal portion of the tube. The protruding portion of the corewire is surrounded by a spring and shapeable into a curve or arc. The cross-sectional shape of the spring may be varied in order to promote bending flexibility and curvature or to favor curvature of a chosen type. The corewire is axially movable with respect to the tube, which compresses or stretches the spring to change the stiffness of the spring. The tube has a proximal portion comprised of a relatively rigid material, such as stainless steel, while a distal portion is comprised of a more flexible material, such as a nitinol.
