This is in the general field of surgical instruments and is specifically a delivery catheter with a flexible, proximally-manipulated hinge or joint region. The inventive catheter may have a balloon region. The catheter may have a shaft of varying flexibility which contains several lumen. The inner, or delivery, lumen generally may be used with a guidewire to access target sites within the body via the flexible, small diameter vessels of the body. The delivery lumen may be also used for placement of occlusive materials, e.g., in an aneurysm. Inflation of the micro-balloon, located near the distal tip of the catheter, is effected using the inflation lumen. The push / pull wire lumen contains a wire, which when manipulated, flexes the catheter's distal tip. The push / pull wire tubing may have a variable thickness to aid in adjusting the degree of flexibility. Moreover, the delivery catheter may be capable of twisting in a helical or corkscrew-like manner for traversing certain vasculature. This may be accomplished by winding the push / pull wire within the catheter and fixedly attaching it. The catheter may further include an entry in the catheter wall to allow for the insertion of a guidewire; this may facilitate the rapid exchange of catheter devices as desired by the user.

A self scrubbing buckling beam contactor for contacting an array of pads positioned on a device under test is described. The contactor consists of three insulating dies: a top, an offset and a lower die separated from each other by an insulated spacer of variable thickness. Each die is provided with holes. The buckling beam has an array of flexible wires positioned substantially perpendicular to the dies, each of the flexible wires crossing a corresponding hole in each of the top, offset and lower dies to allow each wire respectively contact a pad of the device under test. By shifting the center of the hole of the lower die relative to the center of the offset die, the tip of the wire exits from the lower die at an angle with respect to the plane formed by the pads of the device under test. The exit angle of the wire tip is controlled by the relative displacement of the offset die relative to the bottom die, such that the exit angle of the tip of the wire at the bottom die changes when the probe wire is under compression. By applying a reciprocating motion to the tip of the wire contacting the surface of the device under test, a scrubbing motion is achieved that lowers the resistance between the pad of the device under test. In this manner, the tip of the wire cleans the surface of the pads and prevents contaminants from adhering to the tip of the wire.

A helmet liner that is infinitely adjustable by the user in the field is provided. The helmet liner includes front, center and rear cushioning portions with integrally formed spaces between the front and center portions, and the rear and center portions. The integrally formed spaces provide the liner with the ability to independently flex [in one degree of freedom] and bend [in a second degree of freedom] to collapse the spaces without any overlapping of cushioning portions and thereby conform the liner to the hemi-spherical shape of the wearer's head. The spaces provide ventilation for the wearer's head. The helmet liner may also provide for variable thickness of one or more of cushioning portions as well as antimicrobial treatment of the fabric. By increasing the thickness of the rear cushioning portion with respect to the front cushioning portion, the number of optimum fits achieved by the liner is maximized, while biasing the wearers head toward the front of the helmet, thereby increasing the wearer's field of view (FOV).

An apparatus for the deposition of a variable thickness coating onto the inside of a cylindrical tube comprises a variable pressure gas, an cathode coaxially positioned within the cylinder, and a voltage source applied between the cathode and cylindrical tube, which functions as an anode. A radial plasma arc is generated between the anode and cathode at a starting point on the cylinder, and the plasma arc travels down the central axis of the cylinder, providing a helical deposition region on the inside of the cylinder. Selection of the combination of cathode material and gas enable the plasma to generate ionic material which is deposited on the anodic cylinder in the region of the plasma. By varying the pressure of variable pressure gas for each helical path, it is possible to vary the composition of this deposition film.
