20080275537 | Stents with High Radial Strength and Methods of Manufacturing Same - Polymeric stents having fracture toughness and resistance to recoil after deployment are disclosed along with methods of manufacturing such stents. Improvements to mechanical characteristics and other improvements may be achieved by having polymer chains within individual stent struts oriented in a direction that is closer to or in line with the axis of the individual stent struts. The desired orientation of polymer molecules may be achieved by one or any combination of extruding polymers into hollow tubes to induce axially oriented polymer chains, applying a tensile load to polymer tubes to induce axially oriented polymer chains, and radially expanding polymer tubes to induce circumferentially oriented polymer chains. Stent patterns include struts defining diamond shaped cells and/or W-shaped cells. | 11-06-2008 |
20090001633 | Method Of Manufacturing A Stent From A Polymer Tube - A blow molding apparatus for expanding a polymer tube and a method for fabricating a stent using the apparatus is disclosed. The polymer tube is disposed within a tubular mold, over which a heated ring is made of a material having thermal conductivity greater than the tubular mold is translated. The ring is heated with heated fluid streams applied directly onto an outer surface of the ring, or heated fluid circulated within the ring, or an electrically resistive coil within the ring, or combinations thereof. The heated ring uniformly heats a circumference of the tubular mold that, in turn, uniformly heats a circumferential band of the polymer tube. The heated polymer tube is progressively expanded radially and axially while the ring is translated longitudinally over the polymer tube. The expanded polymer tube can be heat set and cooled prior to removal from the tubular mold. | 01-01-2009 |
