  • Publication number: 20070179579
    Abstract: In some embodiments, a paddle lead is implanted within a patient such that the electrodes are positioned within the cervical or thoracic spinal levels. An electrode combination on a first row of electrodes can be determined that is effective for a first pain location with minimal effects on other regions of the body. The first pain location can be addressed by stimulating a first dorsal column fiber due to the relatively fine electrical field resolution achievable by the multiple columns. Then, another electrode combination on a second row of electrodes can be determined for a second pain location with minimal effects on other regions. The second pain location could be addressed by stimulating a second dorsal column fiber. After the determination of the appropriate electrodes for stimulation, the patient's IPG can be programmed to deliver pulses using the first and second rows according to the determined electrode combinations.

    Abstract: A single compression engine transmits first and second discrete cosine transform (DCT)-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of a plurality of DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the plurality of DCT coefficients.

  • Patent number: 7228179
    Abstract: The invention relates to a stimulation device for creating complex or multi-purpose tissue stimulation. Many typical stimulation devices suffer from deficiencies in providing complex stimulation patterns. Using a circuitry operable or programmable to repeat and skip stimulation settings, a complex stimulation set may be created. The repeating and skipping functionality may be implemented in hardware or software. In this manner, complex stimulations may be derived from simple circuitries. Furthermore, these stimulations may be used to treat pain, stimulate bone growth, and control motor disorders, among others.

  • Publication number: 20070010644
    Abstract: An elastomeric urethane composition includes the reaction product of a resin composition, including a polyol, and an isocyanate. The resin composition and the isocyanate are reacted, in the presence of a first and a second catalyst, to form a polyurethane elastomer. The first catalyst includes a metal selected from the group of iron, titanium, zirconium and hafnium. The second catalyst includes an amine. The elastomeric urethane composition may be used in a method of making an article. The method includes reacting the resin composition and the isocyanate to form the elastomeric urethane composition, applying the elastomeric urethane composition to a mold cavity, and allowing the elastomeric urethane composition to cure to form a first layer. The method also includes applying a urethane composition, different from the elastomeric urethane composition, to the mold to form a second layer, curing the article in the mold, and de-molding the article from the mold.

  • Publication number: 20060287686
    Abstract: A system, method, and implantable pulse generator (IPG) device that stores, on the implantable device, two or more treatment-protocol stimulus programs, each preferably having one or more stimsets, preferably as prescribed by a physician. The IPG communicates with an external patient programmer (EPP) to determine which of the stimulus programs should be run at any given time. Programs stored on the IPG are uploaded to the external device, and a selected program retransmitted (either the program itself, or selection information identifying the selected one of the IPG-stored programs) to the IPG for execution. An advanced programmer is used to read and write program instructions to the IPG. In this way, the patient is capable of carrying two or more program options with him, and if the patient uses an EPIPG, he can use any available EPP to power and operate the EPIPG.

  • Patent number: 7150741
    Abstract: The invention is directed to a dose control module for manipulating the dosage of one or more pharmaceutical solutions emanating from an implantable drug infusion pump. The dose control module has a processor and other circuitry for manipulating flow valves and other dose manipulators. Effluent catheters from one or more implantable drug infusion pumps may be connected to the dose control module. The dose control module may direct the effluent pharmaceutical solution to one or more catheters. These catheters direct the pharmaceutical solutions to treatment locations. The invention is also directed to induction coil valves for use in or with the dose control module. The use of induction coils permits the dose control module to determine valve position and counteract large directional magnetic fields produced by MRIs.

  • Patent number: 7127297
    Abstract: An electronic stimulation system is used to control pain over multiple regions of a patient's body. The system has one or more percutaneous leads, each having multiple electrodes, implanted within the patient's epidural space parallel to the axis of the spinal cord. The leads are connected to either a totally implanted system or a radio frequency system. The system is able to treat pain over different regions of a patient's body by “simultaneously” stimulating the patient with at least three different stimulation settings. “Simultaneous” stimulation involves sequentially stimulating the patient with the multiple stimulation settings such that the patient receives the cumulative effect of each stimulation setting, while not perceiving the transition from one stimulation setting to another.

  • Publication number: 20060230023
    Abstract: A digital repository 20 includes data items. A user can add additional functionality or program routines to data item by including as a data item a data processing identifier pointing to at least one data processing routine. Such routines are accessed by a client 22 by sending from a client to the digital repository 20 a request to access a data item, wherein the repository provides an interface description document 32 from the digital repository 20 to the client 22 as the response to the request. The client 22 can then transmit a data processing request from the client to a service 26 identified by the data processing identifier of the interface description document 32, the data processing request including the identifier from the interface description document.

  • Publication number: 20060200210
    Abstract: The application relates to a stimulation device with power conservation functionality. In implantable devices, power supplies may be limited. Replenishing these power supplies may require costly surgery or periodic recharging depending on the model. A method may be implemented that skips or drops periodic pulses without apparently changing the frequency of the pulses. In this manner, the dropped pulses may be undetected by the patient. On the other hand, the dropped pulse represents power savings. Dropping one in ten pulses may lead to a 10% energy savings. The stimulation device may implement the method with one or more counters implemented in hardware or software.
