  • Patent number: 10774858
    Abstract: Provided are assemblies having composite structures interlocked with shape memory alloy structures and methods of fabricating such assemblies. Interlocking may involve inserting an interlocking protrusion of a shape memory alloy structure into an interlocking opening of a composite structure and heating at least this protrusion of the shape memory alloy structure to activate the alloy and change the shape of the protrusion. This shape change engages the protrusion in the opening such that the protrusion cannot be removed from the opening. The shape memory alloy structure may be specifically trained prior to forming an assembly using a combination of thermal cycling and deformation to achieve specific pre-activation and post-activation shapes. The pre-activation shape allows inserting the interlocking protrusion into the opening, while the post-activation shape engages the interlocking protrusion within the opening. As such, activation of the shape memory alloy interlocks the two structures.

  • Patent number: 9681971
    Abstract: A medical device-includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention. A crimping temperature is maintained at about the onset of glass transition of the polymer material to facilitate more rapid stabilization of mechanical properties in the scaffold following crimping.

  • Patent number: 9623813
    Abstract: Fit and finish methods using shape memory polymers (“SMP”) are disclosed herein. In an example of the fit and finish method, a first part and a second part are positioned adjacent to one another such that a shape memory polymer in a temporary shape is adjacent to a gap between the first part and the second part. The SMP is heated to a switching temperature of the SMP, which causes the SMP to initiate conversion to a permanent shape so that the SMP extends into the gap to close the gap between the first part and the second part.

  • Patent number: 9554928
    Abstract: A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes one or more balloon pressurization steps. The balloon pressurization steps are selected to enhance scaffold retention to the balloon while retaining, at least partially, the original balloon folds as the balloon is pressurized and de-pressurized within a crimper head. By at least partially retaining the original balloon folds, a uniformity of scaffold expansion by the balloon is improved.

  • Patent number: 9533786
    Abstract: Provided is a self-closing and automatically fitting device for packaging (e.g. shrink wrapping, fasteners, enclosures of objects). The device includes a wrapping material and/or closure bands/straps which are made of a shape memory material and a non-shape memory material. The device also includes at least one pair of clasp members attached to the wrapping material and/or closure bands/straps. Upon stimulation by a trigger source, the shape memory material deforms and brings the wrapping material to self-assemble about an object to be packed. The self-assembly of the wrapping material and/or closure bands/straps further brings the two clasp members close to each other and facilitate the clasp thereof to form a self-assembled and closed package. The device may also include a motor, a control unit, and sensors which enable a motor actuated fine tensioning of the self-assembled and closed package.

  • Patent number: 9289845
    Abstract: Layered metal deposition by fusion thereof onto a surface of an engineered structural member, without degrading structural performance. The net shape of an exterior member is defined, including a fusion contact area. The structural member is preheated below its maximum operating temperature. An energy beam and feedstock are directed to a feed point in the fusion area, thereby forming a molten puddle fusing the materials together. The feed point is moved relative to the structural member, thereby advancing the molten puddle of presently fed feedstock and rapidly solidifying previously fed feedstock. The energy beam power is modulated to control the size of the molten puddle so as not to exceed a predetermined depth of penetration of the fusion region into the structural member. Advancing the feed point sequentially fuses feedstock into the defined net shape on the structural member.

  • Patent number: 9174403
    Abstract: The present invention is directed to manufacturing processes for manufacturing a single piece of thermostatic pipe from a length of pipe with a female end that is reinforced by a band of reinforcing material extending around the female end. When the pipe and a similar adjacent pipe are threaded together, the band of reinforcing material helps protect the female end against failure due to hoop stresses and/or lateral stresses. In this regard, the reinforcing material is any material with a higher resistance to hoop stresses and/or lateral stresses than the material from which the pipe is made.
