    摘要: The waveform of a blood pressure of a patient is corrected by a pressure correcting mechanism having an air chamber having a volume ranging from 1 to 150 .mu.l and a resistance passage having one end communicating with the air chamber and the other end with a blood pressure measuring line. The resistance passage has a cross-sectional area ranging from 2000 to 160,000 .mu.m.sup.2 and a length ranging from 0.5 to 40 mm. A fluid such as a physiological saline solution filled in the blood pressure measuring line can flow through the resistance passage into the air chamber to dampen an extraneous pressure wave transmitted through the blood pressure measuring line.

    摘要: A tubular body for reducing the rate at which a fluid flows to a predetermined rate with a resistance in a flow control device of a pressure measuring system, includes a tubular member having an axis along which the fluid can flow therethrough, and a land projecting radially inwardly from an inner wall surface of the tubular member. The tubular member and the land are integrally formed as a unitary structure, the land having an orifice extending along the axis of the tubular member. A method of manufacturing the tubular body, and a flow control device incorporating the tubular body are also disclosed.

    摘要: An interventional guiding sheath system can include an inner sheath, an outer sheath, and a filter located between the inner sheath and outer sheath. The filter can be expandable such that it opens to secure the guiding sheath system within a vessel of a patient during an interventional procedure. The inner sheath can include a mesh or other type of opening such that when the filter is collapsed back against the inner sheath, any debris collected by the filter during the procedure can pass through the inner sheath for aspiration out of the vessel. Additionally, a dilator can be used with the inner sheath for, among other things, aiding in placement of the device. The dilator can also be provided with a mesh, a recess, or other type of opening to allow any debris that is collected by the filter to either be stored by the dilator or aspirated from the dilator.
