摘要:
An implant structure for use in pulling two soft body tissue areas closer together in a patient (e.g., two points along or adjacent to the patient's mitral valve annulus) includes at least two tissue anchor structures that are respectively implantable into the two tissue areas. A tether structure links the two tissue anchors and can be shortened and held in that condition by a cinch structure. Bracing structures are used between the anchors and the tether to help keep the longitudinal axes of the anchors transverse to the tether axis even when the tether is under tension. The tether may be sheathed in a cushioning sleeve to help protect adjacent tissue from erosion by the tether.

Soft body tissue structure can be remodeled by shortening the distance between first and second portions of that tissue structure. First and second anchor structures are respectively implanted in the first and second portions of the tissue structure. These anchor structures are linked by a linking structure, the length of which between the anchor structures can be shortened to pull the tissue structure portions toward one another. Each of the anchor structures may include two screw structures that are driven into the associated tissue structure portion transverse to the linking structure and with a spacer between the two screws. The entire prosthesis can be implanted percutaneously if desired. An illustrative use of the prosthesis is to shorten the annulus of a patient's mitral valve, with at least a portion of the prosthesis implanted in the patient's coronary sinus.

Described herein is a computerised method for identifying and classifying edges in a dataset representative of an open-pit mine terrain. The method includes the step of identifying one or more surfaces of the terrain having common topological attributes (306). Then, for each surface identified, edges of the identified surface are detected (308) and each of the detected edges are classified (316) as one of a toe, crest, or other than a crest or a toe. The method also includes the step of updating the dataset (208) with the edges classified as toes or crests.

The invention comprises a completely recessed wall-wash lighting fixture capable of being installed within a ceiling. The lighting fixture comprises a housing, which contains a lamp. The invention may comprise a lighting fixture further comprises a reflector disposed within the housing and adjacent to the first end of the housing. The invention may also comprise a flared lamp shield attached to the housing, which is capable of protecting the lighting fixture from damage. The lamp shield extends below the ceiling when the lighting fixture is installed.
摘要:
A stent scaffold combined with amniotic tissue provides for a biocompatible stent that has improved biocompatibility and hemocompatibility. The amnion tissue can be variously modified or unmodified form of amnion tissue such as non-cryo amnion tissue, solubilized amnion tissue, amnion tissue fabric, chemically modified amnion tissue, amnion tissue treated with radiation, amnion tissue treated with heat, or a combination thereof. Materials such as polymer, placental tissue, pericardium tissue, small intestine submucosa can be used in combination with the amnion tissue. The amnion tissue can be attached to the inside, the outside, both inside and outside, or complete encapsulation of the stent scaffold. In some embodiments, at least part of the covering or lining comprises a plurality of layers of amnion tissue. The method of making the biocompatible stent and its delivery and deployment are also discussed.

The present invention provides plate spinner systems and devices, and methods of using such systems and devices. In preferred embodiments, the systems and devices contain one or more of the following features: a manual power generating component (e.g. a hand crank power supply); a rotor assembly composed of a rotor with brackets for securing a sample holding device such as a sample processing device or a micro-titer plate; a rotor hub that supports nearly all of the weight of the rotor assembly; a manually operated brake; and a kettle cover containing a rotor tachometer.
摘要:
A method of producing male or female sterile plants comprising the steps of transforming plant material with a polynucleotide which encodes at least one enzyme which reacts with a non-phytotoxic substance to produce a phytotoxic one, and regenerating the thus transformed material into a plant, wherein the said non-phytotoxic substance is applied to the plant up to the time of male or female gamete formation and/or maturation, so that the non-phytotoxic substance provides for the production of a phytotoxic one which selectively prevents the formation of or otherwise renders the said gametes non-functional, wherein the enzyme is expressed preferentially in either male or female reproductive structures, characterised in that (i) the non-phytotoxic substance is selected from the group consisting of ester derivatives of non-phosphonate herbicides which herbicides are directly phytotoxic to non-green tissue, D-alpha amino acids, peptide derivatives of non-protein D-alpha amino acids, S-enantiomers of aryloxyphenoxypropionates and S-enantiomers of ester derivatives of aryloxyphenoxypropionates and (ii) the enzyme is selected from the group consisting of carboxylesterases, D-amino acid oxidases, D-amino acid dehydrogenases, D-amino acid racemases, 2-arylpropionyl-CoA epimerases, alpha-methylacyl-CoA racemases, thioesterases and acyl-CoA synthetases.
摘要:
A method and apparatus for a calibrated variable phase offset timing between synchronous clock subdomains is described. In one embodiment, the invention is an apparatus. The apparatus includes a first subsystem and a second subsystem coupled to the first subsystem. The apparatus also includes a clock signal generator coupled to the first subsystem and coupled to the second subsystem. The clock signal generator is to supply a first clock to the first subsystem and to supply a second clock to the first subsystem and to supply a third clock to the second subsystem. Each of the first clock, the second clock and the third clock are derived from a common clock, the first clock having a first predetermined phase offset relative to the third clock, and the second clock having a second predetermined phase offset relative to the third clock. The first predetermined phase offset and the second predetermined phase offset are adjustable based on performance characteristics of the first subsystem and performance characteristics of the second subsystem.
