  • Publication number: 20230208161
    Abstract: An automatic power-off circuit automatically disconnects a path between a battery and a load after the battery supplying power to the load for a specific time period. The automatic power-off circuit includes a first switch, a first capacitor, a first reverse circuit, a timing circuit, and a logic circuit. The first reverse circuit provides a first signal reversed to a potential change based on the potential change of the first capacitor. The timing circuit provides a second signal with the first potential to the logic circuit based on the first signal with the first potential, and adjusts the second signal with the second potential after the specific time period. The logic circuit turns on the first switch based on the second signal with the first potential, and turns off the first switch based on the second signal with the second potential.

  • Patent number: 10525552
    Abstract: 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.

  • Patent number: 10279372
    Abstract: A method for forming a coating on a stent involves spraying or drying a coating on the stent while the stent is supported on a mandrel assembly, during which part of the stent is made to go out of contact with the mandrel assembly.

  • Patent number: 10155247
    Abstract: 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.

  • Publication number: 20180154051
    Abstract: The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.

  • Publication number: 20180142952
    Abstract: A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a dryer having a telescoping plenum which provides a drying chamber for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The drying chamber improves efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provides a platform that can effectively support stents that are over 40 mm in length.

  • Patent number: 9909807
    Abstract: A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a dryer having a telescoping plenum which provides a shield and drying region for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The shield and drying region improve efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provide a platform that can effectively support stents that are over 40 mm in length.
