Variable stiffness steering mechanism for catheters
ActiveUS20110251519A1Enabling controlWithout sacrificing torsional strengthGuide wiresEndoscopesTorsional rigidityEngineering
A catheter assembly including a tapered steering spine having a varying stiffness along an axial length. The tapered steering spine is tailored to provide increasing flexibility from proximal to distal in a way that makes the bend radius more uniform along the length of the steering section. In one embodiment, the tapered steering spine includes structures on adjacent rings that engage with each other when the steering section is flexed to limit the minimum bend radius to a predetermined minimum and which enhances the torsional rigidity of the steering section regardless of the degree of flexure of the steering section. The limited bend radius can prevent excessive bending of components such as fiber optics. The enhanced torsional rigidity can negate the need for torque braid in the section of the catheter shaft that surrounds the tapered steering spine.

When incorporating a strain-inducing semiconductor alloy in one type of sophisticated transistors, the removal of sacrificial cap materials, such as a spacer layer, sacrificial spacer elements and dielectric cap materials, may be accomplished by using, at least in a first phase of the removal process, an efficient etch stop liner material, which may thus reduce the material loss in the drain and source extension regions that are formed prior to the deposition of the strain-inducing semiconductor material.

Disclosed are methods of forming field effect transistor(s) (FET) and the resulting structures. Instead of forming the FET source / drain (S / D) regions during front end of the line (FEOL) processing, they are formed during middle of the line (MOL) processing through metal plug openings in an interlayer dielectric (ILD) layer. Processes used to form the S / D regions through the metal plug openings include S / D trench formation, epitaxial semiconductor material deposition, S / D dopant implantation and S / D dopant activation, followed by silicide and metal plug formation. Since the post-MOL processing thermal budget is low, the methods ensure reduced S / D dopant deactivation, reduced S / D strain reduction, and reduced S / D dopant diffusion and, thus, enable reduced S / D resistance, optimal strain engineering, and flexible junction control, respectively. Since the S / D regions are formed through the metal plug openings, the methods eliminate overlay errors that can lead to uncontacted or partially contacted S / D regions.
