    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.

    Abstract: An endoscope for use in harvesting blood vessels includes a scope body of the type having a lumen extending longitudinally therethrough which itself has a proximal and a distal end. The endoscope includes means for viewing an area adjacent the distal end of the lumen, and the lumen has a lateral dimension of a size sufficient to accommodate the blood vessel being harvested and at least one tool for use in harvesting the blood vessel. A first end of the blood vessel section to be harvested is exposed through an incision in the patient's body. A dissecting tool and a gripping tool are inserted through the lumen of the endoscope and used to dissect the blood vessel away from the surrounding connective tissue of the patient's body, using the viewing means of the endoscope to view this dissection in process within the patient's body. Additional tools are provided for use through the lumen of the endoscope to remove body fluids and coagulate bleeding tissue, and to sever side branches from the blood vessel to be harvested, as well as to sever a distal end of the blood vessel to be harvested when a desired length of blood vessel has been dissected. Only a single small incision in the patient's body is necessary to harvest a relatively long length of blood vessel in a precise and controlled manner through endoscopic vision using the inventive endoscope and its related tools.

    Abstract: An apparatus for selectively measuring central venous pressure and effecting hyperalimentation through a single catheter inserted into a central vein of the patient. The apparatus includes a manometer, a first selector valve connected to an upper portion of the manometer tube, a hyperalimentation fluid supply connected to the valve, a sterile air supply connected to the valve, a second selector valve connected to a lower end portion of the manometer tube, a waste container connected to the second selector valve, and a catheter connected to the second selector valve. The first selector valve is arranged to connect alternatively the hyperalimentation fluid supply or the sterile air supply to the upper end portion of the manometer tube, and the second selector valve is arranged to connect alternatively the lower end portion of the manometer tube selectively to the waste container or the catheter. A check valve may be connected between the waste container and the second selector valve and an isolation valve may be connected between the catheter and the second selector valve. A lock is provided for locking the catheter to the connection to the second selector valve. The selector valves in the illustrated embodiment are defined by two-way stopcocks. The apparatus is completely closed at all times relative to the ambient atmosphere.
