摘要:
A multiple stent structure including a plurality of stent bodies arranged end to end in which adjacent stent bodies of the structure are connected by a severable connecting portion disposed between the adjacent stent bodies is disclosed. A method of coating a plurality of stents including depositing a coating on the multiple stent structure and severing the severable connecting portions to disconnect the plurality of stent bodies is disclosed.
摘要:
A method for coating a stent can involve a device having a drying zone, a spray zone, and movable member for positioning a stent in the drying zone and another stent in the spray zone. Each stent can be on a support. A force can be applied to the outside surface of a stent to prevent rotation of the stent with respect to the support.
摘要:
The present invention involves laser machining polymer substrates to form a stent with laser parameters that minimize damage to the substrate in a surface region adjacent to the machined edge surface. The wavelength and pulse width are selected for this unique application and they can be controlled to minimize the surface modifications (such as voids, cracks which are induced by the laser-material interaction) which contribute to the variation in mechanical properties with distance from the edge surface, bulk mechanical properties, or a combination thereof.
摘要:
A system and method for inspecting stents can involve an inspection camera to take an image of the stent and a computer system for analyzing the image to determine the presence of any coating defects. The determination can be made by masking out a portion of the stent, identifying deviations from a strut edge, and/or highlighting features protruding from a stent external boundary defining an outer diameter. The image can be taken after a focus feedback camera determines the position of the stent.
摘要:
An apparatus for weighing a stent includes a buffer for storing a stent support with a stent mounted thereon, a stent mounting and dismounting assembly that mounts and dismounts the stent from the stent support, a robotic arm for moving the stent support with the stent between the buffer and the stent mounting and dismounting assembly, and a scale assembly for weighing the stent. The stent mounting and dismounting assembly moves the stent into the scale assembly after the stent has been dismount from the stent support.
