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.
