摘要: Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.

摘要: A mold for a medical device balloon has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a cone region and a body region. The cone region is heated to a higher temperature, or the mold wall is formed to deliver applied heat more efficiently to the cone region, relative to the body region of the mold.

摘要: An extrusion control system for use with one or more extruders has a data acquisition module in communication with one or more data acquisition nodes that are associated with an extrusion process. A control module is also in communication with one or more control nodes associated the extrusion process. A synchronization signal to one or more control nodes causes the nodes to adjust to a predetermined setting.

摘要: Medical devices, such as endoprostheses, and methods of making the devices are described. In some implementations, the endoprostheses is a stent having a tubular body with an outer wall surface, and an inner wall surface defining a stent central lumen. One or more regions of the outer wall surface and the inner wall surfaces is formed by a porous, sintered metal layer. One or more regions of the porous, sintered metal layer provides a porous reservoir or media for drug material. The porous, sintered metal layer in one or more regions of the inner wall surface provides relatively decreased friction, increased hardness and lower tack, as compared to excipient polymeric coating material for stents, and are positioned to facilitate improved, relatively lower resistance withdrawal of a delivery balloon from the stent central lumen.
