Abstract: A mixture for intravenous injection to treat damaged vascular structures contains a mixture of carbamide peroxide and a sclerosing agent. The injected mixture expresses blood from the affected vascular structure by formation of bubbles, in situ. The bubbles carry the sclerosing agent into contact with the lining of the vascular structure resulting in destruction. The size of the bubbles may be varied by adding hydrogen peroxide and varying the proportions of carbamide peroxide and hydrogen peroxide in the mixture.

Abstract: Methods for infusing the interior of a blood vessel are practiced with a catheter having an infusion lumen, a plurality of elution holes, a movable barrier (preferably an inflatable bladder) between the infusion lumen and the elution holes, an occlusion balloon, and an inflation lumen. The methods include sealing the elution holes with the movable barrier, inserting the catheter into the blood vessel, inflating the occlusion balloon, unsealing the elution holes, injecting the therapeutic agent through the infusion lumen, deflating the occlusion balloon and removing the catheter from the blood vessel. The methods also preferably include testing the occlusion balloon and priming the infusion lumen prior to sealing the infusion ports and inserting the catheter into the blood vessel.

Abstract: A catheter system for treating pulmonary emboli has a multi-lumen primary catheter for accessing the vascular system. The primary catheter has a balloon on the distal end for occluding the venous tree, preferably distal to the renal veins. A semipermeable membrane is attached to the primary catheter intermediate the balloon and the proximal end of the primary catheter. Oxygen is supplied to the membrane through the primary catheter to enrich the blood in the venous tree flowing to the heart. Other lumen in the primary catheter guide other catheters through the heart to the pulmonary arteries to inject lysing agents, contrast media, medicaments and to remove blood clots and other catheters may extend through the vena cava to other parts of the venous tree to supply the same agents and to remove blood clots there.

Abstract: A preferred apparatus for delivering an intravascular drug such as a sclerosing agent (or a microfoam sclerosing agent) to a varicose vein includes a catheter having three concentric tubes. The innermost tube has a guide wire lumen and an inflation lumen. The distal end of the innermost tube has an integral inflatable occlusion balloon in fluid communication with the inflation lumen. The intermediate tube has a lumen through which the innermost tube extends. The distal end of the intermediate tube has a self-expanding balloon with a plurality of fluid pores in fluid communication with the intermediate tube lumen. The outer tube has a lumen through which the intermediate tube extends. Sclerosing agent is dispensed through the intermediate tube to pores located at the distal end of the intermediate tube or in the self-expanding balloon. Veins are sclerosed as the self-expanding balloon is pulled through and ultimately out of the vein.

Abstract: Methods and apparatus for treating the interior of a blood vessel include a variety of catheter designs, methods and apparatus for occluding a blood vessel, methods and apparatus for locating an occlusion device, methods and apparatus for locating a treating device at the site of blood vessel tributaries, and methods and apparatus for dispensing treating agent.

Abstract: A medical bolster for alleviating the effects of poor circulation supports either the legs above the heart or the heart above the extremities to improve blood and lymph fluid flow in a patient. The collapsible bolster has an articulated frame pivotally connected together for adjusting the angle between the base frame member and the support frame member. A brace extends between the base frame and the support frame to fix and secure the frame in a selected position. The brace has a safety stop to prevent injury during collapse and the brace is oriented to vector the forces within the articulated frame.

Abstract: Disclosed is a thermoplastic, container for storage of solids, viscous or semi-viscous fluids that permit stacking one upon another for easy shipment and/or display. The container utilizes projections and recesses to engage similarly constructed containers for vertical stacking. Additionally, the container includes vertical ribs for enhanced strength. The removable caps used to seal the container include through holes to permit a rigid member to be passed through the length of the openings to apply the necessary torque to loosen the cap. The containers may be variably sized and can be reused.

Abstract: The current invention utilizes the common baseball-type hat or headband, to which is attached one or more arrays of light emitting diodes. It is the object of this invention to provide an efficient lighting apparatus which embodies the principles of an adjustable hat or headband worn on the head, to which a battery-powered light emitting diodeing apparatus is either permanently attached to the hat or headband, or removable attached to the hat or headband by a hook and loop concept.

Abstract: A folding bolster is used to treat circulation problems to prevent pooling of fluids in patients. The bolster has three members connected together end-to-end. A first member has a free end and a hinged end connected to a center member which has a hinged end and flexible joints connecting the base member which includes a ratchet device. The members are folded together to form an adjustable triangular frame with the free end of the first member engaging the ratchet device. A patient is supported by the center member to improve circulation.

Abstract: The present invention is directed towards a method and device for cutting, dilating, tamponading a coronary vessel and with perfusion capabilities. The device consists of instrument general catheter having a distally position cylindrical member surrounded by a dilating balloon. The catheter is designed to be used with a guide wire for positioning the instrument and an advancement catheter permit the proper localization of the instrument inside a coronary artery. There are openings in a proximal cast member to permit the perfusion of blood which passes through the body of the instrument.
