Typically, the radial constraint of the outer radially constraining section is carried out by relative axial movement between the outer radially constraining section and the radially expandable shear barrier.

The biasing ring (8) is surrounded by a reinforcement (9), which bears against it with radial pre-stress.

The distal section has a radially expandable shear barrier which is at least partially radially constrained by an outer radially constraining section.

The needle blocking object is radially and axially constrained in the shielding position.

This device makes it possible to exert the required radial pretension for the rollers which roll on the threaded spindle.

The die (5) is surrounded by a biasing ring (8), which bears against it with radial pre-stress.

Upon entering the outer sheath, the stent device expands radially until radially constrained by the outer sheath.

The rotor (16) includes a sleeve (18) surrounding the magnet core (17) to radially constrain the core during high speed rotation thereof.

A catheter has an energy delivery device positionable in a renal blood vessel and being transformable between a radially constrained low-profile state and a self-expanded deployed state.

The methods are performed such that, due to the stressor layer, the nanowire is subjected to at least one of radial and longitudinal strain to enhance carrier mobility in the nanowire.

At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements.

Means are provided on said tubular shaft for establishing a radial and torsional constraint between the tubular end portion of the shaft and the end portion of the screw received therein and axially connected to the shaft.
