  • Patent number: 9398025
    Abstract: A method for generating and check-controlling a network identity identification code in a network electronic identity is provided for the establishment of a unified network identity management and service ecosystem that effectively protects the network application security and identity information privacy of citizens. A server performs initialization and generates and distributes random numbers while receiving and auditing a request to generate a network identity identification code from a client. If the client passes the audit, encryption coding is performed and a network identity identification code is generated and sent to a network electronic identification card through the client. The network electronic identification card performs check processing of the network identity identification code, and feeds back a result to the server. The server stores the network identity identification code into a database, and informs the user.

  • Patent number: 8703168
    Abstract: An implantable medical device for releasing therapeutic agent having a medical device body and a plurality of reservoir-defining structures disposed on a surface of the body. A reservoir can be defined by the reservoir-defining structures and therapeutic agent may be located in the reservoir. A cover may extend over the reservoir so that the therapeutic agent is released from the reservoir when the medical device implanted. Methods for making the medical device may also include providing a medical device body, positioning a plurality of reservoir-defining structures on a surface of the body to form a reservoir, loading therapeutic agent into the reservoir, and covering the reservoir so that the therapeutic agent may release when the medical device is implanted.

  • Patent number: 8574615
    Abstract: According to an aspect of the present invention, implantable or insertable medical devices are provided which contain (a) one or more depressions that contain at least one therapeutic agent, and (b) a nanoporous coating, disposed over the therapeutic-agent-containing depressions, which regulate transport of species between the therapeutic-agent-containing depressions and the exterior of the device. The implantable or insertable devices are configured to preform a role beyond mere drug delivery, for example, providing mechanical and/or electrical functions within the body, among other functions. An advantage of the present invention is that medical devices may be provided, which release therapeutic agents in quantities far exceeding the void volume within the nanoporous coating, while at the same time providing functionality that extends beyond drug delivery. Such release may further approach or achieve a zero order kinetic drug release profile.
