Abstract: The disclosure describes various aspects of strain management layers for light emitting elements such as light-emitting diodes (LEDs). The present disclosure describes an LED structure formed on a substrate and having a strain management region supported on the substrate, and an active region configured to provide a light emission associated with the LED structure. The strain management region includes a first layer including a superlattice having a plurality of repeated first and second sublayers, and a second layer including a bulk layer. In an embodiment, at least one of the first and second sublayers and the bulk layer includes a composition of InxAlyGa1-x-yN. A device having multiple LED structures and a method of making the LED structure are also described.

Abstract: A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.

Abstract: A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

Abstract: Systems and methods can involve wedge dissectors attached to strips in turn attached to medical balloons, for forming serrations within vascular wall tissue for angioplasty as well as drug delivery.

Abstract: An intravascular device can comprise a carrier and an expansion apparatus. The device can be used for intravascular treatment of atherosclerotic plaque. The carrier can be reversibly expandable and collapsible within a vessel and can have ribbon strips extending between opposite ends in a longitudinal direction of the carrier. The ribbon strips can each be formed with a plurality of elongated protrusions thereon. The expansion apparatus can be used to actuate the ribbon strips each with the plurality elongated protrusions to pierce a luminal surface of the plaque with lines or patterns of microperforations which act as serrations for forming cleavage lines or planes in the plaque.

Abstract: A light-emitting diode (LED) structure includes an active region that has at least one aluminum-containing quantum well (QW) stack that emits light from the LED structure when activated. The LED structure exhibits a modified internal quantum efficiency value, which is higher than a LED structure that does not include aluminum within a QW stack. The LED structure also exhibits a modified peak wavelength, which is longer than an unmodified peak wavelength of the unmodified LED structure.

Abstract: A serration balloon can have a number of different components and can be made in a number of different manners. One or more longitudinally extending members with periodic raised wedges can be attached to a medical balloon. They can be attached with a fiber coating, a polymer coating, or other methods. A polymer matrix can be used to bond the longitudinally extending member to the surface of the balloon. The fiber coating can be, for example, a thread or mesh that secures the longitudinally extending member to the balloon. The medical balloon can be an angioplasty balloon, such as an off-the-shelf angioplasty balloon.

Abstract: A session management function of a 5G system receives information that a secondary authentication is to be done for a given user equipment for authorising user equipment to use a data network; and responsively to the received information, communicates with the data network and receives from the data network an indication; and allows a 5G access to the user equipment so that the user equipment can communicate with the data network according to the indication either without cryptographic protection or with cryptographic protection depending on the indication.
