    摘要: An intravascular stent and method of making an intervascular stent having a hybrid pattern a. The hybrid pattern comprises a plurality of circumferentially self-expansible members comprising a plurality of interconnected, geometrically deformable closed cells, adjacent self-expansible members interconnected by a plurality of bridge members linking a first interconnection between two closed cells in a first self-expansible member to a second interconnection between two closed cells in a second self-expansible member, wherein the second interconnection is circumferentially offset and non-adjacent to the first interconnection.

    摘要: The present invention consists of an implantable structural element for in vivo delivery of bioactive active agents to a situs in a body. The implantable structural element may be configured as an implantable prosthesis, such as an endoluminal stent, cardiac valve, osteal implant or the like, which serves a dual function of being prosthetic and a carrier for a bioactive agent. Alternatively, the implantable structural element may simply be an implantable article that serves the single function of acting as a time-release carrier for the bioactive agent.

    摘要: The present invention provides a system and method for optimizing power consumption in mobile devices. The system comprises a speech codec encoder module and a speech codec decoder module. The number of CPU/DSP/VLIW processor cycles taken to encode and decode the speech signals are significantly reduced to draw lower current by the mobile device. The significant reduction of processor cycles in the speech codec modules enables reduction of power consumption in the talk time. Thus, the invention provides a simple method of optimizing power consumption by reducing number of processor cycles to compress/decompress speech signal of the speech codec modules in mobile devices.

    摘要: A thrombus detection device comprising an elongate tube having at least one opening at a distal end of the elongate tube. A coupling is attached or formed at the proximal end of the elongate tube. The detection of the presence of a thrombus is performed by using a syringe to withdraw blood through the at least one thrombus detection opening at the distal end of the elongate tube. If little or no blood is withdrawn, or if the withdrawal of blood is more difficult than expected, the presence of a thrombus obstructing the openings is indicated.

    摘要: Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. Laminate structures are known to increase mechanical strength of sheet materials such as wood and paper products and are used in the area of thin films to increase film hardness, as well as toughness. Laminate metal foils have not been used or developed because the standard metal forming technologies, such as rolling and extrusion, for example, do not lend themselves to the production of laminate structures. Vacuum deposition technologies can be developed to yield laminate metal structures with improved mechanical properties. In addition, laminate structures can be designed to provide special qualities by including layers that have special properties such as superelasticity, shape memory, radio-opacity, corrosion resistance etc. Examples of articles which may be made by the inventive laminate structures include implantable medical devices that are fabricated from the laminated deposited films and which present a blood or body fluid and tissue contact surface that has controlled heterogeneities in material constitution. An endoluminal stent-graft and web-stent that is made of a laminated film material deposited and etched into regions of structural members and web regions subtending interstitial regions between the structural members. An endoluminal graft is also provided which is made of a biocompatible metal or metal-like material. The endoluminal stent-graft is characterized by having controlled heterogeneities in the stent material along the blood flow surface of the stent and the method of fabricating the stent using vacuum deposition methods.
