  • Patent number: 6311691
    Abstract: A method for determining the shortest distance between the periphery of a lesion and the cut edge of the tissue specimen utilizing a cylindrical tissue specimen. The cylindrical tissue specimen is placed inside a fixative transmitting cylindrical canister for fixation. After the tissue specimen has been fixed and embedded, it is cross-section sliced in planar slices that are perpendicular to the longitudinal axis of the fixed cylindrical tissue specimen. The slicing can be performed with the tissue specimen remaining inside the cylindrical canister or the tissue specimen can be removed from the canister prior to slicing. The tissue slices are mounted on slides and the slides are evaluated to select the slide showing the lesion periphery nearest to the cut edge of the specimen. The shortest distance between the periphery of the lesion and the cut edge of the specimen is measured. Preferably, the measured distance is adjusted for artifacts in the fixation, mounting, embedding and slicing processes.

  • Patent number: 6230713
    Abstract: A treatment plan for patients suffering from a thrombotic event can be determined by measuring membrane bound and/or soluble P-selectin. The degree of reperfusion can be determined by assessing the level of soluble P-selectin subsequent to reperfusion. Additionally, predicting whether thrombolytic therapy will induce reperfusion can be determined by measuring the level of membrane bound P-selectin prior to reperfusion.

  • Patent number: 6220247
    Abstract: A method of performing trabeculodissection to treat glaucoma uses a galvanometric scanning laser delivery system. A scleral flap is cut to expose the treatment area of the trabecular meshwork. The arc of the treatment area is made as wide as the trabecular meshwork limited by the circumference of the limbal area around the patient's eye. A laser, preferably of the excimer type, is used to treat small test areas in successive discrete zones along the arc of the treatment area in the bed of the scleral flap to determine the precise depth of ablation required over the entirety of each zone to promote filtration without penetration of the treatment zone. The laser then treats discrete zones over the length of the arc to remove in scan layers so as to process discrete ablated zones of minimal residual thickness. The treatment of successive zones allows ablation along the length of the treatment arc without interference from actively draining aqueous.

  • Patent number: 6213126
    Abstract: A restriction in a restricted vessel lying closely proximate the heart is bypassed. An aperture is formed in a supply vessel suitable for providing a blood supply. An aperture is formed in the restricted vessel distal of the restriction. Heart tissue is removed from the surface of the heart to form a channel in the heart tissue between the aperture in the supply vessel and the aperture in the restricted vessel distal of the restriction. The channel is covered to form a conduit to conduct blood from the supply vessel to the restricted vessel distal of the restriction.

  • Patent number: 6206004
    Abstract: A method for treating the heart and associated vessels and tissues, by controlling the temperature of the pericardial space and/or introducing therapeutic agents, drugs or the like thereto, includes providing a fluid, liquid(s), gas(es) or mixtures thereof, with or without therapeutic agents, drugs or the like, and heating and/or cooling, this fluid. At a time proximate to the heating and/or cooling of the fluid, the pericardial space is accessed by pericardiocentesis, such that the pericardium is punctured and the pericardial space is instrumentized at a location, and in particular, a location where treatment is desired. The heated and/or cooled fluid is then delivered to the pericardial space. At a time after delivery, the fluid is withdrawn from the pericardium, through either the same catheter, or through another catheter at different point along the pericardium, that was also instrumentized (catheterized) by standard pericardiocentesis procedures.

  • Patent number: 6189537
    Abstract: The invention produces osteoinductive bone using a controlled-flow apparatus. The apparatus allows for the controlled extraction of undesirable constituents from a body tissue. The invention provides for the demineralization of ground bone particles or pieces of cancellous or cortical bone which permits the controlled and reproducible demineralization of bone to produce bone which is maximally osteoinductive. It has been demonstrated that ground cadaveric bone which is demineralized to a residual calcium level approximating 2% by dry weight of bone is optimally osteoinductive as assayed using in vivo and in vitro assays of osteoinductivity. The controlled-flow apparatus includes one or more solution containers which supply solutions to be pumped into one or more vessels filled with tissue samples to be extracted. Solvent outflowing from the vessels can be monitored for pH, calcium ion concentration or conductivity as a basis for determining when extraction is complete.

  • Patent number: 6186146
    Abstract: An in situ treatment of an organ, such as a kidney, of a living body, having a disease or tumor. The method includes: subjecting a diseased or tumorous organ, such as a kidney, to an effective amount of a therapeutic agent, by infusing the agent via blood entering the organ, creating an isolated section in a major vein spanning the area where the tributary veins connect with the major vein, the major vein and tributary veins being directly associated with the organ; passing contaminated effluent blood from the tributary veins of the organ to the isolated section and capturing the effluent blood therein; and, evacuating the captured blood from the isolated section without exposing the contaminated effluent blood to other organs or tissues of the body and without interrupting the general circulation in the system of the body.

  • Patent number: 6183416
    Abstract: Method for diagnosis of inflammatory conditions in the intestinal canal of humans, characterized in that NO is measured in the lumen of the intestines. The NO level obtained is then compared with the level obtained for healthy individuals or with the level obtained for the same individual at another occasion. An increased level compared to the normal levels in the intestines of the healthy population is an indication of an inflammatory condition in the intestine.
