Apparatus with visual marker for guiding deployment of implantable prosthesis
First Claim
1. An apparatus for use by an operator in a cavity of a mammalian body with a scope having a distal face providing a field of view comprising:
- a flexible elongate member having a distal extremity adapted for extending into the cavity and a proximal extremity accessible from outside of the mammalian body when the distal extremity is disposed in the cavity,an expandable prosthesis, means for releasably securing the prosthesis to the distal extremity of the flexible elongate member, wherein the means for releasably securing the stent comprises a colored mesh; and
a visual marker in the form of a colored band extending around the colored mesh;
wherein the visual marker is colored with a colorant to enhance visualization and is capable of being seen under direct vision within said cavity using said scope without the need of fluoroscopy;
wherein the band is a tubular member, and wherein the color of the band contrasts with the color of the mesh.

Abstract
An apparatus for use by an operator in a cavity of a mammalian body with a scope having a distal face providing a field of view. The apparatus includes a flexible elongate member having a distal extremity adapted for extending into the cavity and a proximal extremity accessible from outside of the mammalian body when the distal extremity is disposed in the cavity. An expandable prosthesis is releaseably secured to the distal extremity of the flexible elongate member. A visual marker capable of being seen by the operator in the field of view is secured to one of the distal extremity of the flexible elongate member and the prosthesis for facilitating placement of the prosthesis in the mammalian body.

21. An apparatus for use by an operator in a cavity of a mammalian body with a scope having a distal face providing a field of view comprising:
-
a flexible elongate member having a distal extremity adapted for extending into the cavity and a proximal extremity accessible from outside of the mammalian body when the distal extremity is disposed in the cavity, an expandable prosthesis stent having first and second ends, means for releasably securing the prosthesis to the distal extremity of the flexible elongate member and a visual marker capable of being seen by the operator in the field of view secured to the prosthesis for facilitating placement of the prosthesis in the mammalian body;
wherein the visual marker is colored to enhance visualization and permits the placement of the prosthesis without the need of fluoroscopy and is capable of being freed from the prosthesis;
wherein the band is a tubular member.
