Abstract
A composite implantable prosthesis including a scaffold with a plurality of axially spaced apart sections connected by one or more bridges, each bridge including one or more hinges, and methods of making the prosthesis. The material of the bridges may be generally distinct from the material of the scaffold.
Claims31
A method comprising a step of making an implantable prosthesis by forming a scaffold, the scaffold comprising:
- a plurality of axially spaced-apart circumferential sections defining a cylindrical portion around a longitudinal axis;
- an elastic first material;
- and
- one or more bridges comprising:
- one or more hinges;
- and
- a flexible second material different from the first material,
- wherein each bridge is disposed between two adjacent circumferential sections.
5 more elements
A method of making a composite implantable prosthesis, comprising:
- forming a generally cylindrical-shaped stent from a first material having sufficient elasticity and radial rigidity to remain open when inserted into a lumen, the stent defining a plurality of circumferential sections;
- and
- connecting adjacent circumferential sections of the stent using one or more hinged connectors formed from a second material having sufficient flexibility to conform the stent to contours in the lumen.
