Abstract:
A method of crimping a stent to a support element is disclosed, the method comprising: positioning a polymeric stent around a support element; heating the stent, wherein the heated stent is above ambient temperature; and allowing the heated stent to radially contract onto the support element, wherein the heated stent radially contracts at least partially due to heating the stent.
Abstract:
A method for patterning a substrate includes forming a material layer on the substrate; performing a first etching on the material layer to form a pattern; measuring the pattern of the material layer using an optical spectrum metrology tool; determining whether the measuring indicates that the etching step achieved a predefined result; and producing an etching recipe and performing a second etching of the material layer using the etching recipe if the predefined result was not achieved.
Abstract:
An air cooled switching unit for a motor drive includes a plurality electrical switches and a plurality of heat pipe assemblies. Each heat pipe assembly includes a thermally and electrically conductive evaporator, a condenser, and at least one heat pipe extending between the evaporator and condenser. Each of the switches is abutted with an evaporator of at least one of the heat pipe assemblies for conduction of both electrical power and heat between the switch and the evaporator. Each heat pipe assembly further includes an electrically conductive base abutted with the evaporator, and the air cooled switching unit further includes a plurality of power lugs each connected to a base of a respective one of the heat pipe assemblies for input or output of electrical power to the base and the evaporator plate abutted with the base. Each heat pipe assembly includes at least one evaporator defined by a metallic plate. The condenser of each heat pipe assembly includes a plurality of parallel spaced-apart cooling fins. The at least one heat pipe of each heat pipe assembly includes a sealed pipe containing a phase-change material for transferring heat from said evaporator to said condenser. The at least one heat pipe includes a first end located in the metallic plate and a second end in contact with and extending through the cooling fins of the condenser. A temperature feedback system derives air flow velocity through the condenser.
Abstract:
A patterning device holding apparatus includes a support platform unit with a plurality of first positioning projections and a gripper unit. The gripper unit includes a head portion and a plurality of second positioning projections disposed on the head portion, and a rolling member set at a base portion. The grapping and releasing of the patterning device is achieved by the rotation of the gripper unit about a pivot substantially parallel with the center axis of the rolling member. The first and second positioning projections corporately abut against the edges of a patterning device to fix the patterning device in place.
Abstract:
Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.
