  • Patent number: 8380302
    Abstract: An implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can include one or more MRI Safe components. In an example, the implantable device includes a capacitor including a first electrode including a first slot extending from a perimeter of the first electrode to an interior of the first electrode. A second electrode is separated from the first electrode by a first distance. The second electrode includes a second slot extending from a perimeter of the second electrode to an interior of the second electrode. The first and second slots are configured to at least partially segment surface areas of the first and second electrodes, respectively, to reduce a radial current loop size in each of the first and second electrodes.

  • Patent number: 8326436
    Abstract: Systems and methods for improving response of implantable leads to magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. In various embodiments, the lead includes an inner conductor that is helically shaped and radially surrounded, at least in part, by one or more high-voltage conductors. The high-voltage conductor can be mechanically and/or electrically coupled, via a coupler, to the shocking coil. The pitch of the inner and/or outer conductor can be varied (e.g., continuously or at certain points) along the length of the lead. In some embodiments, the filar thickness, the pitch, and the mean coil diameter of the inner coil, the high voltage conductor coil, and the shock coil can be configured such that these coils have a desired inductance value when subjected to externally applied electromagnetic energy at radio frequencies commonly generated by MRI scanners (e.g., 40 MHz to 300 MHz).

  • Publication number: 20110035228
    Abstract: A system, apparatus, and methods for facilitating a sales team to create, populate, and maintain a customer sales knowledgebase. The customer sales knowledgebase may be used to by sales people in developing a sales strategy, for example identifying key people within a customer entity for a particular sales pitch and determining how to approach key people. The knowledgebase may be utilized as a present transaction resource or for aggregating customer data for use by other members of a sales team. After sales people interact with key persons within the customer entity, the knowledgebase provides a common repository for sharing customer impression data, detailing which sales strategies were successful and to what extent the sales strategies were successful. Furthermore, the knowledgebase may also be used by corporate decision makers or sales managers for sales to facilitate sales forecasts and determine which customers to target.

  • Patent number: 7759042
    Abstract: Laser induced thermal imaging (LITI) donor films, and methods of preparing them, having a substrate, a light-to-heat conversion layer, and a pattern-directing layer. The pattern-directing layer can include patterns of self-assembled monolayer regions, hydrophilic and hydrophobic regions, positively or negatively charged regions, or a series of raised or recessed features. It can also be used to generate charge patterns and magnetic patterns. The pattern-directing layer causes patterning of a transfer layer applied to it, resulting in a templated transfer layer. When imaged, the LITI donor film transfers at least a portion of the templated transfer layer to a permanent receptor while maintaining the pattern substantially intact in the transferred portion.
