摘要:
Fluoroelastomer (FKM) rubber-containing articles that exhibit highly desirable long-term effective antimicrobial characteristics are provided. Such articles are in either solid or blown (foam or sponge) state (or combinations of both in multilayered forms) and can be utilized in a variety of applications. This invention utilizes the presence of non-sulfur-based curing systems and agents, such as bisphenols, that permit vulcanization and do not irreversibly bind silver ions thereto, thereby resulting in long-term antimicrobial performance of the rubber article. This invention further provides a simple method of producing such an antimicrobial vulcanized fluoroelastomer rubber-containing article. This invention also encompasses certain non-silicone pre-vulcanized raw rubber formulations made from at least a majority by weight of FKM rubber that include silver-based components to provide highly desirable long-term antimicrobial characteristics within the ultimate cured FKM articles made therefrom.

摘要:
A tissue surface reatment apparatus includes a housing having a proximal end, a distal end including a tissue contacting surface, an interior defined by the housing and a handpiece coupled to the housing. The contactine surface has a plurality of apertures. An energy delivery device including an electrode is positionable in the housing interior. The electrode includes a tissue penetrating distal end in substantial alignment with an aperture. The electrode is configured to be advanced from the housing interior through the aperture and into a target tissue site to define an ablation volume at least partly bounded by a tissue surface. An advancement device is coupled to the energy deliveru device and is at least partly positionable within at least one of the housing or the handpiece. The advancement device is configured to advance the electrode fdro the housing interior into the target tissuesite and withdrawal the electrode into the housing interior. A cable is coupled to the housing or the energy delivery device and is configured to be coupled to an energy source.

A method of controlling ablation volume depth includes providing a treatment apparatus. The apparatus comprises a housing having a proximal and distal end including a tissue contacting surface. The housing defines an interior with an energy delivery device positionable in the interior. The energy delivery device includes at least one electrode with a tissue penetrating distal end and is configured to be advanced from the interior into a target tissue site to define an ablation volume. An advancement device is coupled to the energy delivery device and is configured to advance the at least one electrode. The at least one electrode is advanced to a selected deployment depth beneath a tissue surface while avoiding a critical structure. Energy is delivered from the energy delivery device. An ablation volume is created at a controlled depth below the tissue surface responsive to the deployment depth while minimizing injury to the critical structure.

A process for placing a roller burnished finish on the central portion of an unfinished lathe-turned heater tube includes controlling the rotational speed of the burnishing rollers and the pressure of the burnishing rollers against the central portion of the heater tube so that tooling marks are no longer apparent under substantially 10× magnification and the length of the central portion of the heater tube increases by no more than 0.002 inches per inch of length of the central portion of the heater tube.
摘要:
A method of preparing an enzyme-labeled ligand for use in specific binding assays for determining said ligand or a specific binding partner thereof, by covalently coupling said ligand or a binding analog thereof to an organic prosthetic group and combining the resulting coupled product with an apoenzyme to form a conjugated enzyme complex with said prosthetic group in said coupled product. Preferably, the conjugated enzyme complex in the resulting labeled conjugate exhibits holoenzyme activity which is affected by binding of said labeled conjugate by a specific binding partner of said ligand. Preferred prosthetic groups are flavin mononucleotide, heme, and, especially, flavin adenine dinucleotide, with preferred apoenzymes being apoperoxidase and, especially, apoglucose oxidase.
摘要:
A seismic resistant cluster bracket for mounting to an electrical power-line pole and supporting power distribution transformers includes a rectangular support frame which has upper and lower horizontal cross beams secured to left, right, and center vertical strong-back struts. Pole-mount brackets protruding rearward from the center strong-back are provided with bolt holes for receiving bolts to attach the support frame to a power pole. Top and bottom safety mount brackets, each having vertical stabilizer ribs for engaging indentations of a rear transformer bracket are attached to the front of each strong-back. A pair of adjustable extension length diagonal braces spaced equal distances laterally outwards from the center strong-back are pivotal mounted to the rear side of the support frame, extendable to adjustable lengths and boltable to a power pole to secure the frame against movements relative to the power pole as a result of static weight loading or seismic vibrations.
摘要:
A tissue ablation system including numerous components and methods is described herein for encircling target tissue and generating tissue ablation volumes in various biological tissues. The biological tissue includes tissue of a variety of organs of the human body including the liver, spleen, kidney, lung, breast and other organs, but is not so limited. The tissue ablation device comprises an energy source and at least one trocar coupled to the energy source, the trocar having a body, a proximal end, and a distal end. The trocar carries an electrode array that comprises a plurality of electrodes, each electrode of the plurality of electrodes is configured to extend from the trocar when moved from a retracted state to a deployed state, and to have at least one radius of curvature in the deployed state so that the electrode array forms a series of shaped electrodes in the deployed state.
