  • Patent number: 8712539
    Abstract: Techniques that involve application of one or more rules to a “parent” program to generate a plurality of different “child” programs are described. Each of the rules may define a respective electrode configuration modification, and each child program may be a variation of the parent based on a modification of the electrode configuration of the parent according to one of the rules. The systems or devices may generate further generations of child programs from a previous generation child program using the same one or more rules. The child programs may be provided to a user, so that the user may test the efficacy of the new programs, assisting the user in identifying desirable programs. The child programs may be relatively minor variations of the parent program, and the user may “fine tune” a generally desirable parent program by testing the child programs.

  • Publication number: 20140012330
    Abstract: Methods of stabilizing the sacroiliac joint by placing an expandable device in the joint to generate laterally opposing forces against the iliac and sacral surfaces of the SI joint to securely seat the device in a plane generally parallel to the SI joint. The expandable device is coated with or otherwise contains a bone material to promote fusion of the joint. The expandable device used in methods of the present invention can be, for example, an expandable cage, a balloon, a balloon-expandable stent or a self-expanding stent.

  • Patent number: 7885712
    Abstract: Techniques for increasing the safety of medical device programming using general purpose hardware, such as a general purpose personal computer, are described. In some embodiments, a system includes an intermediate computing device comprising an applications module. Information from the applications module, such as instructions for an implantable medical device (IMD), may be presented to a user via a user input terminal that is separate from the intermediate computing device. A user may interact with the user input terminal to select an instruction from the applications module, and the intermediate computing device may transmit the selected instruction to the IMD. In some embodiments, the intermediate computing device comprises a web server and the user input terminal comprises a web browser configured to access the web server. In other embodiments, the intermediate computing device comprises a client server and the user input terminal comprises a client.

  • Patent number: 7848819
    Abstract: Techniques for increasing the safety of medical device programming using general purpose hardware, such as a general purpose personal computer, are described. Some embodiments include a watchdog module that is serviced by the general purpose hardware, a mediator module that monitors programming instructions from the general purpose hardware, and/or a safe mode input that may be activated by a user. In some embodiments, a system comprises an implantable medical device, an intermediate device, a computing device that communicates with the implantable medical device via the intermediate device. The intermediate device may provide any one or more of the safety measures described above. In some embodiments, the intermediate device is dedicated hardware, and critical programming functions are provided by the intermediate device, rather than the general purpose hardware.

  • Patent number: 7774067
    Abstract: Techniques for automatically generating neurostimulation therapy program groups are disclosed. The techniques may include receiving rating information and information describing actual therapy effects for a plurality of tested programs, and receiving target therapy data describing target therapy effects. The techniques may include automatically generating plurality of program groups based on the rating information and a comparison of actual effects to the target therapy effects. Actual effects and target therapy effects may be, for example, actual paresthesia areas and target paresthesia areas. The techniques may also include determining whether a sufficient number of programs have been tested to generate a desired number of programs groups and, if a sufficient number have not been tested, automatically generating additional programs based on the tested programs, and automatically generating program groups from the tested and automatically generated programs.
