    摘要： Sampling apparatus designed for aspirating, diluting and mixing a small sample of fluid in precise amounts and delivering the mixture to a scientific apparatus at a place remote from the place of aspiration. Operation of the device may be manual but is preferably automatic. The apparatus is designed to process a plurality of sample fluids with no cross-contamination between samples. In essence, the apparatus is a fluid handling system including a sample pick-up assembly in fluid communication with an automatic valve assembly having two operative positions. The automatic valve assembly is in fluid communication with a dilutor assembly having a sample pump and a diluent pump operable by a common means. A mixing and delivery assembly is also in fluid communication with the automatic valve assembly and includes a cup designed for bidirectional rotation with an annular space about the cup. A dispensing probe dispenses into the cup precise amounts of sample and diluent in a predetermined ratio to each other and, following rotation of the cup to achieve the mixture of sample and diluent, an aspirator probe enters the mixture and delivers an amount thereof to an adjacent scientific instrument. The apparatus further includes a means for expelling the remainder of the mixture from the cup into the annular space surrounding the cup, and from there through a valve, to waste.

    摘要： Devices, systems and methods are provided for deployment of one or more functional devices, such as therapeutic or diagnostic medical devices, or positioning devices, at various locations relative to a defined operative path. The devices, systems, and methods can include a guide system and a positioning element. The guide system defines the operative path when deployed within a patient's body. The positioning element cooperates with the guide system to define one or more positions relative the defined operative path from which the one or more functional devices are deployed. The present inventions allow for the accurate and reliable placement of the one or more functional devices at the one or more positions relative the operative path. In one embodiment, the functional device is an ablation device adapted to ablate cardiac tissue for the treatment of cardiac arrhythmias, such as atrial fibrillation.

    摘要： A system for analyzing a biological fluid or the like includes a series flow loop that extends between an inlet valve array and an outlet valve array. The flow loop includes an analysis region to which a measuring system is connected in sensing relation and an accumulator chamber connected to the outlet of the analysis region. The inlet valve array is arranged to selectively and alternately connect a sample inlet port and an auxiliary fluid reservoir to the flow loop while the outlet valve array is arranged to selectively connect a controlled source of reduced pressure to the flow loop. The volume of the accumulator chamber is at least as great as the volume of the flow loop (including the analysis region) between the inlet valve array and the accumulator chamber and the system is arranged to capture reduced pressure in the flow loop, the captured reduced pressure then being used to provide the sole transfer force to gently and reliably transfer a minute quantity of fluid to be analyzed from the sample inlet port through the analysis region and at least partially fill the accumulator chamber.

    摘要： A total carbon dioxide analyzer system has a reaction chamber that includes a tube and a piston mounted for sliding movement in the tube to change the volume of the chamber. A valve coupled to the chamber has a sample inlet port and a reagent inlet port, and is movable between a first state in which the sample inlet port is connected to the chamber, a second state in which the reagent inlet port is connected to the chamber, and a third state in which the reaction chamber is sealed. A system controller coordinately operates the valve and moves the piston to increase the volume of said chamber to draw sample into the chamber for mixing with an acid reagent in the chamber, and then seals the chamber and increases the volume of the chamber to facilitate the release of carbon dioxide. A transducer then senses the pressure of carbon dioxide in the reaction chamber.
