摘要： A method of treating a perforator vein comprises applying ultrasound to the perforator vein and occluding the perforator vein with the ultrasound. An apparatus for treating blood vessels comprises an ultrasound emitter, wherein the ultrasound emitter is configured to emit ultrasound at multiple therapeutic ultrasound frequencies during a treatment cycle. The apparatus further comprises an acoustic coupler in sonic communication with the emitter, wherein the acoustic coupler has an acoustic coupling surface configured to contact a patient and facilitate delivery of ultrasound to the patient and wherein the acoustic coupler provides a conduction path for ultrasound from the emitter to the acoustic coupling surface. The apparatus further comprises an acoustic coupler containing a displaceable acoustic coupling material. The apparatus further comprises an acoustic coupler configured to vary the length of the conduction path in accordance with variation in the thickness of the acoustic coupling material disposed between the emitter and the acoustic coupling surface.

摘要： A catheter includes multiple primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes a resistive element located at the working end of the catheter. Separation is maintained between the leads such that each lead can individually receive power. The catheter can include a lumen to accommodate a guide wire or to allow fluid delivery. Energy is applied until the diameter of the hollow anatomical structure is reduced to the point where occlusion is achieved. In one embodiment, a balloon is inflated to place the resistive elements into apposition with a hollow anatomical structure and to occlude the structure before the application of energy. The inflated balloon impairs blood flow and facilitates the infusion of saline, or medication, to the hollow anatomical structure in order to reduce the occurrence of coagulation and to improve the heating of the structure by the catheter.

摘要： An apparatus and method are described for quickly inducing therapeutic hypothermia of the heart by perfusing the myocardium with hypothermic fluid in alternatingly antegrade and retrograde directions. The apparatus and method provide rapid cooling of the affected myocardium to achieve optimal myocardial salvage in a patient experiencing acute myocardial infarction. The therapeutic hypothermia system includes one or more coronary artery perfusion catheters, a coronary sinus perfusion catheter and a fluid source for delivering a hypothermically-cooled physiologically-acceptable fluid, such as saline solution, oxygenated venous blood, autologously-oxygenated arterial blood and/or an oxygenated blood substitute. The system may also include one or more guidewires, subselective catheters and/or interventional catheters introduced through a lumen in one or more of the perfusion catheters.

摘要： A system for establishing differential perfusion without the use of an occlusion balloon or other flow separator devices. The flows through two lumens are controlled such that the blood flow issuing from one lumen terminating in the aortic arch supplies the entire demand of the cerebral subcirculation while the blood flow issuing from a second lumen terminating in the descending aorta supplies the entire demand of the corporeal subcirculation. When the two flows are properly balanced, an inversion layer forms therebetween and no intermixing of the two flows takes place.

摘要： The cannula of the present invention is useful for standard gravity drainage or vacuum assisted/suction drainage. The cannula of the present invention has a flexible shaft composed of a tubular body and an expandable scaffolding. The expandable scaffolding has a contracted position, facilitating insertion into a vessel and an expanded condition configured to allow optimal drainage in a vessel. The cannula is inserted into a vessel and navigated into an operative position within the patient's venous system. Once the cannula is in the proper position, the scaffolding is expanded either through passive, active, mechanic, hydraulic, pneumatic, thermal or electrical actuation. The cannula of the present invention is capable of expanding a collapsed vein to its normal diameter and/or capable of supporting the vein when suction is applied to the cannula to help increase fluid flow through the cannula.
