A multi-layer cover for an electronic device having one or more of a sensor panel, a proximity sensor, an ambient light sensor, and a display device can include an outer hardcoat, a structural layer, an IR transmissive ink layer, a mask layer, and a backside hardcoat. The backside hardcoat can reduce cover warpage, enable full surface lamination of the cover to the sensor panel, prevent bubbles from forming in transparent windows in the cover, enable a wider range of functional inks to be applied in various layering orders to allow certain types of light to pass through while blocking others, and hide the sensors to provide a seamless, uncluttered visual appearance.

A process for trimming a photoresist layer during the fabrication of a gate electrode in a MOSFET is described. A bilayer stack with a top photoresist layer on a thicker organic underlayer is patternwise exposed with 193 nm or 157 nm radiation to form a feature having a width w1 in the top layer. A pattern transfer through the underlayer is performed with an anisotropic etch based on H2 / N2 and SO2 chemistry. The feature formed in the bilayer stack is trimmed by 10 nm or more to a width w2 by a HBr / O2 / Cl2 plasma etch. The pattern transfer through an underlying gate layer is performed with a third etch based on HBr / O2 / Cl2 chemistry. The underlayer is stripped by an O2 ashing with no damage to the gate electrode. Excellent profile control of the gate electrode is achieved and a larger (w1−w2) is possible than in prior art methods.

Surgical systems for less invasive access to and isolation of an atrial appendage are provided. A suturing grasper compresses soft tissue structures and deploys one or more sutures through complimentary pledget(s) carried by the grasper. The pledgets are reinforced, containing support members that define the profile of the stitch and distribute stresses applied by the stitch, once tightened, over a length of tissue. This hardware may be applicable to other surgical and catheter based applications as well including: compressing soft tissue structures lung resections and volume reductions; gastric procedures associated with reduction in volume, aneurysm repair, vessel ligation, or other procedure involving isolation of, resection of, and reduction of anatomic structures.

A structure intends to arrange the appearance of furniture at a connecting portion between a first member having stiffness and a second member movable relative to the first member and having stiffness without forming the connecting portion in an unnaturally large diameter. More specifically, the present invention provides a structure for connecting members comprising: a first member having stiffness; a second member movable relative to the first member and having stiffness; and a spring member in which an end portion thereof is connected to the first member and other end portion thereof is connected to the second member so as to accumulate a reaction force by elastic deformation, wherein the spring member is formed into a frame-like shape extending along the first and second members.

An epitaxial growth film formation method allowing to adequately prevent the sticking phenomenon spreading over both a wafer and a susceptor when a horizontal disc-like susceptor is used to form an epitaxial growth film is provided. The epitaxial growth film formation method is a method of forming a vapor growth film on the wafer by placing the wafer having a diameter smaller than that of the susceptor approximately horizontally in substantially a center section on the horizontal disc-like susceptor, wherein the vapor growth film is formed on the wafer by bringing a circumferential recess step adjacent to a bottom inside from an edge part of the wafer and a convex step provided on a circumference of an upper surface inside from the edge part of the susceptor into contact.

Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure comprising a plurality of fingers which are radially outwardly expandable with respect to a longitudinal axis to permanently engage the interior wall of the left atrial appendage, wherein the filtering membrane is attached to the support structure extending across the ostium of the left atrial appendage.

A flexible actuator assembly (20) including a flexible bladder device (22) having an expandable sealed chamber (23) adapted to substantially directionally displace between a deflated condition and an inflated condition, displacing a proximal portion (25) of the bladder device (22) away from a distal portion (26) thereof. An elongated tendon member (27) includes a distal portion (28) oriented outside the chamber (23), while an anchor portion (30) extends into the chamber (23) through a distal opening (31) in the bladder device (22). The tendon anchor portion (30) is further coupled proximate to the bladder proximal portion (25) in a manner adapted to: selectively invert displaceable portions (32) of the bladder device (22) when urged toward the deflated condition to position the anchor portion (30) and the bladder proximal portion (25) relatively closer to the bladder distal portion (26); and selectively evert the inverted displaceable portions (32) of the bladder device (22) when displaced toward the inflated condition which positions the anchor portion (30) and the bladder proximal portion (25) relatively farther away from the bladder distal portion (26) for selective movement of the tendon distal portion (28) between an extended condition and a retracted condition, respectively.

Luminal endoprosthesis formed of a multi-layer braided framework. The framework is devoid of any cover layer, and formed of a plurality of stabilized layers of biocompatible metal wires which are interlaced, forming a lattice, a plurality of wires of a given layer being integrated in the lattice of the adjacent layers. The mechanical characteristics of an outermost layer is so that when in place, the layer applies against a vessel wall, the other layers extending substantially along cylindrical surfaces distinct from the outermost layer so as to form a multi-layer mat which affects the haemodynamic of a flow of blood passing along or through this mat and preventing a growing of plaque.

Systems for sheath fluid and sample fluid transport from containers to an analytic device, such as a flow (cell) cytometer, are disclosed. These systems are sterile and remain so, as they are closed to the ambient environment. As a result, fluids of high purity reach the analytic device, and in the case of a flow cytometer, the desired cells are sorted in sort of high purity.

A composite hard mask is disclosed that prevents build up of metal etch residue in a MRAM device during etch processes that define an MTJ shape. As a result, MTJ shape integrity is substantially improved. The hard mask has a lower non-magnetic spacer, a middle conductive layer, and an upper sacrificial dielectric layer. The non-magnetic spacer serves as an etch stop during a pattern transfer with fluorocarbon plasma through the conductive layer. A photoresist pattern is transferred through the dielectric layer with a first fluorocarbon etch. Then the photoresist is removed and a second fluorocarbon etch transfers the pattern through the conductive layer. The dielectric layer protects the top surface of the conductive layer during the second fluorocarbon etch and during a substantial portion of a third RIE step with a gas comprised of C, H, and O that transfers the pattern through the underlying MTJ layers.
