    摘要： A stent delivery device is disclosed that includes an inner tube having a distal portion which carries the stent on the delivery device. At least part of the inner tube is formed from a spirally wound wire. A movable outer tube is used to constrain the stent in a radially contracted state on the distal portion of the inner tube. A substantially straight elongate wire is configured inside the spirally wound wire and bonded at the distal and proximal portions of the wound wire. The outer tube may have at least one side port adjacent to the distal portion in communication with the annular space between the outer tube and the inner tube allowing radiopaque fluid to be injected through the annular space and out the side port in the vicinity of the stent.

    摘要： A prosthesis delivery and deployment device includes an elongate and flexible outer catheter. The outer catheter has a tubular wall of layered construction, including a translucent inner liner running the complete catheter length, and three outer layers including a translucent distal layer, an opaque medial layer and an opaque proximal outer layer. The outer layers are adjacent one another and are bonded to the liner. A braid composed of helically wound metal filaments is disposed between the liner and the proximal and medial outer layers, and includes a distal portion between the liner and a proximal portion of the distal outer layer. The liner and distal outer layer provide a translucent distal region of the catheter that is adapted to constrain a radially self-expanding prosthesis in a radially reduced, axially elongated state. Because the stent constraining region is translucent, an endoscope can be used to visually monitor the stent when so constrained. Radiopaque markers can be mounted to the outer catheter and to an inner catheter used to deploy the prosthesis, to afford a combined visual and fluoroscopic monitoring for enhanced accuracy in positioning the prosthesis, both before and during its deployment.

    摘要： A stent, an intermediate article in the manufacture of a stent, and a method of forming a stent from a workpiece are disclosed. A portion of the wall thickness of a workpiece may be removed, demarcating the structural framework of a stent from the remainder of the workpiece material during a cutting process. In some embodiments, a residuum layer of material remaining after a cutting process may have a recessed surface in relation to a first surface of the structural framework of the stent formed in the workpiece. In some embodiments, a plurality of kerf channels may be cut in a workpiece to demarcate a structural framework of a stent from waste material of the workpiece. In some embodiments, a series of perforations may, at least in part, demarcate the structural framework of a stent from the remainder of the workpiece material. The waste material and/or residuum material may be removed from the structural framework of a stent during a post-cutting process.
