  • Patent number: 10537710
    Abstract: In some examples, a catheter includes a catheter body including an outer jacket and an inner liner. The inner liner may include a proximal section including a proximal end of the inner liner and a distal section including a distal end of the inner liner. The distal section may include an inner liner defining a plurality of cuts. Each cut may extend at least partially through the liner wall. The one or more cuts defined in the liner wall of the distal section of the inner liner may increase a bending flexibility of the distal section relative to the proximal section of the inner liner, while maintaining a suitable tensile strength of the distal section.

  • Patent number: 10331526
    Abstract: Some aspects of the disclosure include a self-refresh entry sequence for a memory, such as a DRAM, that may be used to avoid a frequency mismatch between a system processor and a system memory. The self-refresh entry sequence may signal the memory to reset the frequency set point state and default to the power-up state upon a self-refresh process exit. In another aspect, a new mode register may be used to indicate that the frequency set point needs to be reset after the next self-refresh entry command. In this aspect, the processor will execute a mode register write command followed by a self-refresh entry in response to the occurrence of a crash event. Then, the memory will reset to the default frequency set point by the end of self-refresh entry execution.

  • Patent number: 9855400
    Abstract: A catheter having an multilayered shaft section with a first layer formed of a polyimide first material and a second layer formed of a second material. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. However, in alternative embodiments, a thermoplastic polyimide is used. The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400° C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.
