摘要： An adhesive system with material and structural heterogeneity is described. The adhesive system comprises a tape having a spatially heterogeneous physical property, the spatially heterogeneous physical property is configured to enhance the adhesive strength of the adhesive system when the adhesive system is in contact with a substrate and/or attain adhesion directionality. The spatially heterogeneous physical property can include a bending stiffness. Heterogeneous variations in the bending stiffness can be achieved by variations in the tape's thickness, elastic modulus and/or Poisson's ratio. Heterogeneity in thickness can be attained by mold pressing and/or patterned laminated structures. Elastic modulus heterogeneity can be achieved by masked irradiation of the tape, where the tape is made of an irradiation-sensitive material. Also described is an adhesive system with a patterned film that exhibits adhesion directionality when the adhesive system is in contact with a substrate.

摘要： Systems and methods for manipulating light with tunable ferroelectric photonic devices. Devices having tunable properties that exhibit photonic bandgap behavior are fabricated from ferroelectric materials. Apparatus is provided to apply tuning signals to the ferroelectric material using one or more of electric fields, mechanical forces, optical fields, and thermal fields. Control circuitry is provided to generate the control signals needed to apply the tuning signals. Input and output ports are provided to allow input signals to be received and to provide output signals. In some cases, a feedback loop is provided to use a portion of the output signal as a diagnostic signal for control of the operation of the device within an acceptable range. It is expected that ferroelectric photonic devices operating according to principles of the invention will be useful for a wide variety of applications, including optical switching, optical modulation, optical computing, and performing logic optically.

IPC分类号： A61F2/06
摘要： A delivery assembly includes a catheter, a generally helical endoluminal prosthesis, placeable in a radially contracted state on the catheter, means for engaging portions of the prosthesis to maintain it in the contracted state, and means for controllably releasing the portions so the prosthesis controllably expands. A delivery catheter comprises a first, flexible, polymer-based tube and a second, metal tube with flexibility enhancing relief areas to enhance the bending flexibility while retaining good torsional stiffness. A coiled endoluminal prosthesis system may include means for rotating a delivery catheter while axially releasing the prosthesis. A release element may be retracted simultaneously with rotation of the delivery catheter. The prosthesis may be configured to reduce or eliminate any difference between the length of the prosthesis when expanded and contracted.

摘要： A coiled ladder stent (12) comprises side rails (14, 16) and rungs (18) connecting the rails. At least one rung has lower strength portion (24) or is an enhanced flexibility (28) rung, or both. The lower strength portion is positioned at a reduced strength fracture location (26) along the rung so to promote any fracture of the ladder stmt at the fracture location along the rung to help prevent fracture of a rail. One way to make the lower strength portion is to make the cross-sectional area of the lower strength portion less than the average cross-sectional area of the rung. The enhanced flexibility aspect helps to accommodate relative movement between the side rails. Doing so helps to prevent fracture of the rails and rungs. In some embodiments of the invention the enhanced flexibility rung comprises one or more nonlinear, such as generally S-shaped or generally U-shaped, portions.
