    Abstract: A method and apparatus for treatment for body structures, especially internal body structures involving disorders involving unwanted features or other disorders, that does not require relatively invasive surgery, and is not subject to other drawbacks noted with regard to the known art. A relatively minimally invasive catheter is inserted into the body, treatment of the body structures is applied using the catheter, and the unwanted features or disorders are relatively cured using the applied treatments. The applied treatments can include application of energy or substances, including application of energy (such as of radio frequency energy, microwave energy, or laser or other electromagnetic energy) or substances (such as collagen or other bulking, plumping, or shaping agents; saline or other energy-receiving electrolytes; astringents or other debulking, reducing, or shaping agents; antibiotics or other bioactive, chemoactive, or radioactive compounds). More than one applied treatment can be performed, either in conjunction, in parallel, or seriatim, so as to achieve a combined effect more substantial than any one individual such applied treatment.

    Abstract: The invention provides a method and system for treatment of body strictures to restore luminal diameter to within a normal diameter range, in which the stricture is dilated to stretch its lumen to a desired diameter, collagen is exuded near to existing tissue of the stricture so as to be absorbed by that tissue or adhere to that tissue, making a collagen-enhanced tissue structure, and energy is emitted to affect the collagen-enhanced tissue, such as by ablation or by hardening. Ablation and hardening may be repeated so as to create a set of layers of hardened collagen in the form of a supporting frame, preferably having a hollow cylindrical shape. Dilation of the stricture is achieved by expanding one or more balloons, or by the pressure of exuded collagen, until the stricture is larger than a normal diameter range. When energy is emitted into the collagen, the stricture contracts back to the normal diameter range, either by ablation of excess tissue or by plating of the stricture wall. The stricture's tissue is also isolated by a set of balloons at either or both ends of the stricture, so as to isolate the stricture and restrict the collagen to the stricture's tissue. The stricture's tissue is also supported by a stent, which is preferably tackwelded onto the stricture's tissue using collagen. Collagen adheres to the stent, which supports the stricture's tissue until the stent is absorbed into that tissue.

    Abstract translation: 本发明提供了一种用于治疗身体狭窄的方法和系统，以将管腔直径恢复到正常直径范围内，其中狭窄被扩张以将其内腔拉伸至期望的直径，胶原蛋白渗透到狭窄的现有组织附近，以便 被该组织吸收或粘附到该组织，形成胶原增强的组织结构，并且发射能量以影响胶原增强组织，例如通过消融或硬化。 可以重复消融和硬化，以便产生一组支撑框架形式的硬化胶原层，优选具有中空圆柱形状。 通过扩张一个或多个气囊或通过渗出的胶原的压力来扩张狭窄，直到狭窄大于正常直径范围为止。 当能量发射到胶原中时，通过消融多余的组织或通过电镀狭窄壁，狭窄可缩回到正常直径范围。 狭窄的组织也通过一组气囊在狭窄的两端或两端分离，以隔离狭窄并将胶原限制在狭窄的组织上。 狭窄的组织也由支架支撑，支架优选使用胶原粘合到狭窄组织上。 胶原蛋白粘附到支架上，其支持狭窄的组织，直到支架被吸收到该组织中。
