摘要: A light-diverting catheter tip is provided according to embodiments disclosed herein. The light-diverting catheter tip may be coupled with the distal tip of a laser catheter and divert at least a portion of the light exiting the distal tip of the laser catheter such that the spot size of the laser beam on an object after exiting the catheter tip is larger than the spot size of the light entering the catheter without the catheter tip. The catheter tip may be removably coupled with the catheter or constructed as part of the catheter. In other embodiments, the catheter tip may conduct fluid and/or divert fluid at the tip of the laser catheter.

摘要: This invention is an improved method and device for treating varicose veins 200 or the greater saphenous vein 202. The method comprises the use of infrared laser radiation in the region of 1.2 to 1.8 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed. The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308. A motorized pull-back device 104 is used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.

摘要: Guided ablation instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias, including atrial fibrillation. In one aspect of the invention, a percutaneous catheter is disclosed with an endoscope positionable in the instrument's distal end region to obtain an image. The image allows the clinician to determine whether contact has been achieved (or blood has been cleared from an ablative energy transmission path) before ablation begins or while ablation is occurring. In one embodiment, percutaneous ablation catheters are disclosed having at least one central lumen and one or more balloon structures at the distal end region of the instrument. Also disposed in the distal end region are an illuminating light source and an endoscope capable of collecting sufficient light to relay an image to the user. The instruments can further include an ablation element. The ablation element can be a contact ablation element, or a radiant energy emitter, which is preferably independently positionable within the lumen of the instrument and adapted to project ablative energy through a transmissive region of the instrument body (and/or balloon) to a target tissue site proximate to the pulmonary veins. The energy can delivered without the need for contact between the energy emitter and the target tissue so long as a clear transmission pathway is established. The endoscope element of the instrument allows the clinician to determine the position of the instrument and, if radiant energy is to be employed, see if such a pathway is clear. Moreover, because the position of the radiant energy emitter can be varied, endoscopic guidance permits the clinician to select a desired location and dose for the lesion.

摘要: The present invention is directed to systems and methods for thermal therapy, especially to detection-guided, -controlled, and temperature-modulated interstitial thermal therapy. Thermal therapy may be used to treat the tissues of a patient. In the case of interstitial thermal therapy, energy is applied to generate heating of the tissue to affect treatment, such as, for example, thermally inducing tissue damage (e.g. thermally-induced tissue necrosis), which may be useful in treating tumors and/or other diseased tissues. Since targets for thermal therapy are internal to the patient, the use of detection guidance may be useful in locating and monitoring treatment of a target tissue.
