Abstract
A method for producing a radially expandable prosthesis by cutting a pattern in a tubular member, which member has an outer diameter at least as great as the expanded diameter of the prosthesis.
Claims20
A method of producing a radially expandable prosthesis, comprising:
- providing a tubular member having an outer diameter;
- cutting a pattern in the tubular member to provide a tubular prosthesis where the tubular prosthesis is adapted to have a compressed diameter for endoluminal delivery and an expanded diameter for use upon implantation;
- where the tubular member outer diameter is at least as great as the prosthesis expanded diameter.
A method of producing a radially expandable prosthesis, comprising:
- providing a tubular member having an outer diameter;
- laser cutting a continuous pattern in the tubular member to provide a tubular prosthesis where the tubular prosthesis is adapted to have a compressed diameter for endoluminal delivery and an expanded diameter for use upon implantation;
- where the tubular member outer diameter is at least as great as the prosthesis expanded diameter.
A method of producing a radially expandable stent, comprising:
- providing a tubular member having an outer diameter;
- laser cutting a zigzag pattern to provide a zigzag stent comprising apexes and struts;
- where the zigzag stent is adapted to have a compressed diameter for endoluminal delivery and an expanded diameter for use upon implantation;
- where the apexes have a width less than the struts;
- where the struts comprise integral barbs;
- where the tubular member outer diameter is at least as great as the expanded diameter of the stent.
