Devices for implantation into an intervertebral disc can include a membrane support member to augment a disc having a defect. A defect in the anulus of a disc can be repaired using a prosthesis such as a barrier. The barrier can include a sealant and an enlarger. The barrier can be implanted into the disc using a delivery cannula, an advancer and at least one control filament to control the positioning of the barrier. A stiffening element can be included within the barrier to impart stiffness to the barrier. The support member can also be connected to an anchor.

A method for forming a self-aligned contact on a semiconductor substrate provided with a plurality of field-effect transistors. The method comprises the steps of forming a first insulating layer comprising a nitride along a profile of a gate structure and a junction region, forming a temporary layer comprising a doped oxide on the first insulating layer, removing a portion of the temporary layer by performing a selective etch of the oxide with a mask while leaving a plug portion of the temporary layer over the junction region, forming a second insulating layer comprising an undoped oxide in a region where the portion of the temporary layer is removed, removing the plug portion by performing a selective etch of the undoped oxide to form a contact hole, removing a portion of the first insulating layer at a bottom of the contact hole, and forming a conductive contact in the contact hole.

Methods and apparatus for use in repairing an atrioventricular valve in a patient are provided. The methods comprise accessing the patient's atrioventricular valve percutaneously, securing a fastening mechanism to a valve leaflet, and coupling the valve leaflet, while the patient's heart remains beating, to at least one of a ventricular wall adjacent the atrioventricular valve, a papillary muscle, at least one valve chordae, and a valve annulus to facilitate reducing leakage through the valve.

The types of quasi-planar CMOS and FinFET-like transistor devices on a bulk silicon substrate are disclosed. A first device has a doped and recessed channel formed in a shallow trench sidewall. A second device has a doped, recessed channel and has a plurality of edge-fins juxtaposed on an edge of an active region of the device. A third device has an undoped recessed channel formed in a sidewall of a shallow trench, wherein the undoped recessed channel further has a plurality of edge-fins disposed thereon. Additionally, an extra mask may be added to each device to allow for fabrication of both conventional transistors and FinFET-like transistors on bulk silicon. The extra mask may protect the source and drain areas from recess etching of the silicon substrate. Several methods of fabricating each device are also disclosed.

A needleless luer access connector is disclosed having a septum disposed in a housing. The septum has a proximal portion with a cross section, a medial portion with a cross section smaller than the cross section of the proximal portion, and a distal portion. A longitudinal slit extends through the septum from the proximal portion to the distal portion. The septum and housing are designed so that septum will not be rotated or removed from the housing when the connector is accessed by a male luer taper. In addition, the septum and housing are designed to bias the slit at the distal portion closed and so a male luer connector does not have to extend completely through the distal portion to open the slit at the distal portion. Finally, the septum and housing are designed to minimize the amount of dead space in the connector when accessed with a male luer taper.

To store an input string of M N-tuples of bits, a substitution transformation is selected in accordance with the input string and is applied to the input string to provide a transformed string of M N-tuples of bits. M or more memory cells are programmed to represent the transformed string and preferably also to represent a key of the transformation. Alternatively, the memory selectively programs each of M or more cells to a respective one of 2N states. A mapping that maps the binary numbers in [0,2N−1] into respective states is selected in accordance with the input string and is used to program M cells to represent the input string. Preferably, a key of the mapping is stored in the memory in association with the M cells.

The present invention relates to a soft capsule which is easily disintegrated in the stomach, wherein the contents thereof are not easily leaked at the time of mastication, which is obtained by providing a soft capsule comprising (2R)-2-propyloctanoic acid or a salt thereof with at least one property, preferably all properties, selected from (A) wherein it has a strength of 150 to 400 N by a cracking test; (B) wherein it has a disintegration time of 3 to 10 minutes by the disintegration test stipulated in Japanese Pharmacopoeia; (C) wherein the capsule shell has a shell thickness of 0.05 to 0.50 mm; (D) wherein the capsule shell has a first seam thickness of 0.10 to 0.55 mm; (E) wherein the capsule shell has a second seam thickness of 0.05 to 0.50 mm; (F) wherein the capsule shell has a water content of 5.0 to 9.0%.

A nasal cannula, for supplying a respiratory gas to a patient, comprising: a pair of spaced apart supply lines which each have a head at one end thereof with a discharge opening therein. The opposite end of each supply line is connectable to a respiratory gas source. Each head is sized to be snugly received and retained within one of the nasal cavities of the patient while forming a sufficient leakage passage, between a portion of inwardly facing nasal cavity skin of a patient and a portion of an exterior surface of the head, to facilitate exhausting of any excess respiratory gas supplied to the patient through the leakage passage and also facilitate inhalation of any room air required in excess of the respiratory gas to be supplied to the patient. The invention also relates to a respiratory therapy system incorporating the nasal cannula, a method of treating a patient with sleep disorder by using the nasal cannula, a diagnostic tool for measuring nasal cavity pressure of a patient, and a method of using the diagnostic tool for measuring nasal cavity pressure of a patient.

A band clamp used to connect tubular bodies such as vehicle exhaust system components. The band clamp has a band extending from a first end to a second end and includes a pair of spaced ribs extending at least part way between the first and second ends. A tightening mechanism is connected to the band and includes two clamp members movable toward and away from each other for tightening and loosening of the band. The band clamp further includes a gasket located on an inner surface of the band between the ribs and extending between the first and second ends. The use of the ribs with the interposed gasket provides a mechanical interlock of the band clamp with the tubular bodies while providing a hermetic seal at the junction between the two bodies.

A current sensor for measuring an electric current flowing through a current bus bar includes: a magnetic core with an opening, through which the current bus bar passes with a predetermined interval; and a first magnetic sensor for detecting magnetic flux density in the magnetic core, the magnetic flux density generated by the electric current passing through the current bas bar. The magnetic core has a first gap and a second gap. The first magnetic sensor is disposed in the first gap. The second gap is capable of preventing magnetic saturation of the magnetic core.
