摘要： Methods for making scaffolds for delivery via a balloon catheter are described. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.

摘要： A method and apparatus for electropolishing a workpiece without immersing the workpiece in a bath of electrolytic solution. The workpiece is held in an atmospheric environment, while electrolytic solution is discharged from a reservoir in the form of a plurality of jet streams onto the surface of the workpiece. A voltage difference is applied across the workpiece and the jet streams, thereby inducing a current to flow, between the workpiece acting as anode and the jet streams acting as cathode. The workpiece may be rotated about an axis and moved linearly along the same axis while the jet streams of electrolytic solution are discharged onto the workpiece. Anodic dissolution causes polishing of the workpiece surface. The electrolytic solution may be collected after discharge and recycled back into the reservoir, after being filtered and cooled.

摘要： An improved expandable stent for implantation in a body lumen, such as an artery, and an improved method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cut cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements, the elements having a rectangular cross-section from cut-to-cut. The individual radially expandable cylindrical elements are disposed in an undulating pattern. The stent is manufactured by direct laser cutting from a single metal tube using a finely focused laser beam originating from a diode pumped fiber laser with an external pulse generator and passing through a coaxial gas jet structure to impinge on the working surface of the tube as the linear and rotary velocity of the tube is precisely controlled. To optimize the cut, the laser parameters may be adjusted and/or the laser pulse may be shaped.
