    摘要： The invention provides a system and method for harvesting a vessel section. The system comprises an endoscope, at least one harvesting tool, and an elongated instrument comprising a shaft and a housing. The shaft includes a viewable region along a length of the shaft and a lumen to slidably receive the endoscope. The housing is releasably engaged with the shaft and includes an elongated opening to provide a working area adjacent to a vessel for the harvesting tool. The method includes making an incision at a point corresponding to the proximal end of the vessel section to be harvested. A shaft is inserted through the incision and adjacent to the vessel section. A housing is slidably engaged with the inserted shaft. Harvesting operations are performed in a working area defined by sidewalls of the housing. The harvesting operations are visually monitored through the shaft.

    摘要： A system and method for determining a coagulation time, e.g., TT, PT, aPTT, and ACT, of a test sample deposited in a test cartridge is disclosed. A cartridge housing having upper and lower major sides and a minor sidewall encloses a test chamber having a test chamber pivot element and is provided with a cartridge port for introducing a test sample into the test chamber. Ferromagnetic agitator vane leaflets extend from an agitator pivot element supported by the test chamber pivot element intermediate the upper and lower major sides for rotational motion. The agitator vane leaflets can be swept, in response to an external magnetic field, through the test sample in the absence of coagulation. A timer is started when the agitator movement is commenced whereupon the agitator moves freely. Resistance to agitator movement due to coagulation is detected, and the coagulation time is measured.

    摘要： A system and method for determining a coagulation time, e.g., thrombin time, PT, aPTT, and ACT, of a blood sample deposited in a test cartridge is disclosed. The test cartridge includes a blood receptacle that is open to the atmosphere into which a blood sample is to be deposited, a vacuum port that is open to atmosphere, and a spiral capillary within the test cartridge having a capillary length and cross-section area, a first capillary end of the spiral capillary open to the blood receptacle and a second capillary end of the spiral capillary open to the vacuum port, whereby the spiral capillary is closed to atmosphere. When a blood sample is deposited in the blood receptacle, a vacuum is drawn through the vacuum port and the blood is drawn through the spiral capillary until coagulation occurs. A pressure change is detected, and the coagulation time is measured.

    摘要： Methods and apparatus employed in surgery involving making precise incisions in vessels of the body, particularly cardiac blood vessels in coronary revascularization procedures conducted on the stopped or beating heart are disclosed. Such incisions are created by applying an elongated electrosurgical cutting electrode to the outer surface of the vessel wall in substantially parallel alignment with the body vessel axis, the elongated electrosurgical cutting electrode having a predetermined cutting electrode length exceeding the cutting electrode width. RF energy is applied between the electrosurgical cutting electrode and the ground electrode at an energy level and for a duration sufficient to cut an elongated slit through the vessel wall where the elongated electrosurgical cutting electrode is applied to the surface of the vessel wall.
