    摘要： The present invention provides a method and apparatus for treating a vascular occlusion and preventing or reducing ischemic consequences of such an obstruction. The medical device of the present invention may include an elongate body defining a proximal end and a distal end, where the elongate body may also define an injection lumen, an exhaust lumen, and a guidewire lumen. A first expandable element may be coupled to the elongate body, where the first expandable element is in fluid communication with the injection lumen and the exhaust lumen. Further, a perfusion path may be disposed within the elongate body, and a sheath may be movably disposed about at least a portion of the elongate body. The medical device may further include a second expandable element disposed about the elongate body, as well as second inflation and exhaust lumens.

    摘要： A method is disclosed for cooling a limited portion of a body organ by placing a cooling device into a blood vessel within a target organ; and activating the cooling device to cool tissue proximate the cooling device to a temperature below +34 degrees Centigrade. The blood vessel can be a vein or an artery and the cooling device can be a fixed diameter catheter or it can include a balloon. More particularly, the method of cooling can provide a method for treating injured ischemic and infarcted tissue by placing a device capable of passage through the vasculature into a target organ, wherein the device is capable of providing sufficient thermal exchange at a working region thereof to cool adjacent tissue; and activating the device to cool adjacent tissue to a temperature in the range of 0 degrees Centigrade to +36 degrees Centigrade. The method can further include placement of a second device capable of passage through the vasculature into the target organ, wherein the second device is capable of at least partially removing a blockage from a blood vessel.

    摘要： A method is disclosed for treating an aneurysm or vascular defect by cooling a target tissue region of the aneurysm or vascular defect to a temperature below body temperature for a preselected time period. The method entails thickening, strengthening, or increasing the density of a blood vessel wall by cooling the blood vessel wall with a cryogenically cooled device. The method also includes irradiating the inner wall of a blood vessel around an aneurysm or vascular defect with various forms of energy to delay or halt aneurysm or vascular defect formation. An energy-emitting element is disposed on the distal end portion of a catheter device to be disposed proximate the aneurysm. Various forms of energy, including visible light energy, laser light energy, ultrasound, microwave and radiofrequency sources may be used to irradiate and treat the aneurysm. In addition, the method may include irradiating a tissue site concomitantly with other treatments, including the delivery of vaso-occlusive compounds, mechanical intravascular devices, or an endovascular graft to the target tissue region.

    摘要： The present invention provides a method for prophylactically treating a vessel region at risk for the development of vulnerable plaque with cryogenic energy. In general, a cryogenic catheter is inserted into the patient's vascular network and manipulated towards a treatment site. The catheter is then activated so as to cool the tissue at the treatment site to a predetermined temperature for a desired amount of time in order to induce the formation of scar tissue, which may include collagen or smooth muscle cell formation. It is understood that a variety of cryogenic catheter configurations can be used to cool the treatment site.

    摘要： A method is disclosed for treating an aneurysm by cooling a target tissue region of the aneurysm to a temperature below temperature for a preselected time period. The method entails thickening, strengthening, or increasing the density of a blood vessel wall by cooling the blood vessel wall with a cryogenically cooled device. In particular, a device having a heat conductive cooling chamber is disposed proximate to the aneurysm site; and a cryogenic fluid coolant is directed to flow inside the chamber to create endothermic cooling relative to the aneurysm. The method also promotes the growth of collagen and elastin in vascular tissue. Tissue cooling temperatures range from +20 to −20 degrees Celsius. The duration of treatment by application of cooling ranges from 15 seconds to up to 20 minutes or more. The method includes treating the aneurysm both from inside and outside the blood vessel wall forming the aneurysm.
