Abstract
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.
