  • Patent number: 9248542
    Abstract: An apparatus for processing a medical stent that includes a holding device for holding a stent and a processing device for processing the stent held by the holding device that includes a first chamber for a fluid medium adapted to exert pressure around the stent. The first chamber for the fluid medium at least partially surrounds or encompasses the stent in the holding device that may include a housing which substantially encloses the first chamber for the fluid medium. A method of processing a medical stent is described. The method may include holding a stent with a holding device, and processing the stent with a processing device while holding the stent with the holding device. Holding the stent may include pressurizing a first chamber for a fluid medium to exert pressure around the stent. A method of producing or manufacturing a stent according to this method is described.

  • Publication number: 20140341251
    Abstract: The invention relates to a system (1) for detecting defects (12) within a structure of struts (2) forming a stent (3), the system comprising a power supply (8) for applying an electrical potential to a proximal end (9) and to a distal end (10) of said stent (3) in order to establish an electrical current flow between said proximal end (9) and said distal end (10), and a temperature sensor (7) such as a infrared camera, adjacent to said stent (3) for detecting a defect (12) within said structure of struts (2), said temperature sensor (7) being adapted to measure a temperature profile of said stent (3). Further, the invention relates to a respective method for detecting those defects (12).
