  • Publication number: 20070073344
    Abstract: A device for temporarily sealing an opening in a blood vessel is provided. The device comprises a cutting mechanism for creating an opening in a blood vessel and a seal for sealing the opening in the blood vessel. The seal is delivered through an inner lumen of a tool body coupled to the cutting mechanism. Methods for using the device to construct an anastomosis between two vessels are also provided.

  • Publication number: 20070015970
    Abstract: 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.

  • Publication number: 20070005084
    Abstract: The invention provides a system and method for harvesting a vessel section. The system comprises a vessel support member, a handle, and a tubular cutting device. The vessel support member is introduced into the vessel section to be harvested. The tubular cutting device may comprise an outer tubular member or an outer and an inner tubular member. The outer tubular member carries at least one cutting element. The tubular member or members are advanced over the vessel section and vessel support member to core out the vessel section and tissue adjoining the vessel section.

  • Publication number: 20060036274
    Abstract: The invention provides a system and method for harvesting a vessel section. The system comprises an endoscope, a harvesting tool, and an elongated instrument including a transparent distal nose portion, an intermediate portion having a recessed working area, and a proximal portion having at least one passageway to allow the harvesting tool access to and the endoscope visualization of the working area. The method includes making an incision at a point corresponding to the proximal end of the vessel section being harvested. The endoscope is positioned in the nose portion of the instrument, and instrument is inserted through the incision and partially into the body. Tissue is bluntly dissected away from the vessel using the nose portion. The endoscope is repositioned adjacent to the recessed working area, and a harvesting tool is inserted into the working area through the passageway and visually monitored with the endoscope.

  • Publication number: 20050255601
    Abstract: 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 comprises 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.

  • Publication number: 20050233460
    Abstract: 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.

  • Publication number: 20050033277
    Abstract: 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.
