Abstract: In accordance with the inventive concepts, provided is a tissue sampling apparatus and method. In various embodiments, the tissue sampling apparatus and method is a cryobiopsy tissue sampling apparatus and method. A cryobiopsy apparatus can be a cardiac cryobiopsy apparatus that includes an intravenous probe having at least one tip capable of reaching temperatures sufficient to freeze tissue such that the tissue adheres to the tip. The tip preferably remains at the freezing temperature through retraction of the probe so that the adhered tissue can be collected for its intended post-extraction purpose.

Abstract: A medical device may include a sheath, and an elongate member disposed within a distal portion of the sheath, the elongate member configured to reciprocally move between a sheathed configuration and a deployed configuration. The elongate member may be substantially linear and disposed within the sheath while in the sheathed configuration and extend distally from the sheath in a first direction in the deployed configuration. The elongate member may include a first bend disposed distal to the distal portion of the sheath, the first bend directing the elongate sheath in a second direction that is substantially opposite to the first direction, and a second bend distal to the first bend, the second bend directing the elongate sheath in a third direction substantially transverse to the first and second directions.

Abstract: A system including a valve trim having a plurality of flow paths, wherein each flow path of the plurality of flow paths includes a series of stages, and a plurality of expansion zones disposed in series with the series or stages, wherein each expansion zone of the plurality of expansion zones is disposed between a sequential set of adjacent upstream and downstream stages of the series of stages, wherein each expansion zone of the plurality of expansion zones is configured to flow a fluid in a direction that is generally transverse to directions of flow in both the adjacent-upstream stage and the adjacent-downstream stage, and wherein each expansion zone of the plurality of expansion zones is in line with one of the adjacent-upstream stage or the adjacent-downstream stage and offset from a different one of the corresponding adjacent-upstream stage or the adjacent-downstream stage.

Abstract: An apparatus that includes a chemical-injection management system. The chemical-injection management system may include a tree interface configured to couple the chemical-injection management system to a tree and a positive-displacement flow meter.

Abstract: Provided is a valve, including an in-line flow passage, a shut-off mechanism, and a multi-stage throttling section disposed in the in-line flow passage. Further provided is an in-line valve, including a flow control component and a sealing component, wherein the flow control component and the sealing component are separate from one another.

Abstract: A mechanism for constructing a software-based instrument panel or front panel in which the components correspond directly with sections of code in a textual language program is disclosed. The textual language program relates to how the panel updates and operates in a continuous fashion. Icons representing panel components are selected from a component library window displayed to a user. The act of dragging the icon representing the components into the Graphical Panel Layout Window automatically causes the corresponding code to be added to the textual language program and displayed to the user in a Program Dialog Window. The present invention displays both a Graphical Panel Layout Window showing the components in the instrument panel and a Program Dialog Window showing the lines of code for the textual language program controlling the operation of the components in the instrument panel. A library containing I/O dialog devices is also presented and displayed to a user.

Abstract: Provided is a valve, including an in-line flow passage, a shut-off mechanism, and a multi-stage throttling section disposed in the in-line flow passage. Further provided is an in-line valve, including a flow control component and a sealing component, wherein the flow control component and the sealing component are separate from one another.

Abstract: Systems, methods, and devices are disclosed, including a system that has a trim with a plurality of flow paths. In certain embodiments, each flow path includes a series of stages and an expansion zone disposed in series between each of the stages. The expansion zones are configured to flow a fluid in a direction that is generally perpendicular to directions of flow in both an adjacent-upstream stage and an adjacent-downstream stage.

Abstract: Graphical programming or modeling environments in which a preview window of an object is provided are disclosed. The preview window may be provided when the pointer of a pointing device hovers over an object and automatically disappear when the pointer of the pointing device is placed out of a predetermined region relating to the object. The object can be hierarchical so that the object includes a subsystem. Another preview window may be provided when the pointer of the pointing device hovers over the subsystem and automatically disappear when the pointer of the pointing device is placed out of a predetermined region relating to the subsystem. The subsystem of the object may also include another subsystem.
