  • Patent number: 7959553
    Abstract: A tissue illumination system and a method for harvesting a section of a blood vessel from a patient's body for further use. The tissue illumination system includes a light catheter inserted into a lumen of the blood vessel section to illuminate the vessel section and vessel side branches with an intensity which is visible to the physician from an exterior of the vessel section and also includes a viewing element insertable into the lumen and capable of viewing the illuminated vessel section. The tissue illumination system also includes at least one tool insertable into the lumen and used to harvest the vessel section.

  • Patent number: 7691084
    Abstract: Therapeutic devices that provide support or pressure to tissue. Devices contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state. Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient. Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.

  • Patent number: 7211040
    Abstract: A system and a method for harvesting a section of a blood vessel from a patient's body for further use. The system includes an expandable hood that creates a workspace for the dissection and removal of the vessel and a telescoping device that has tools at its distal end. The blood vessel is cut at a distal location and a light catheter inserted to illuminate the area of dissection. The system can remove a section of the saphenous vein for use in coronary bypass surgery.
