Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

Systems and methods for treating cellulite including an apparatus that applies or a method involving disrupting, stretching, re-orienting or tearing septa to eliminate or reduce the appearance of cellulite. In one approach, an expandable member is placed between tissue layers to stretch or tear septa connecting tissue layers between which fat deposits are contained.

Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.

Devices and methods for locating sinus ostia and positioning a guide wire within the sinus ostia. The subject devices include a shaft having a distal end, a proximal end, a curved region located between the distal and proximal ends, and an interior channel, an extensible and retractable guide wire movably mounted within the interior channel and a probe tip joined to the guide wire. Certain devices further include expandable portions for engaging and treating body anatomy.

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

A dilator assembly comprising an elongated body having a proximal end and a distal end, a first lumen extending along the body, a second lumen extending along the body so that it is a parallel to the first lumen, and a joint lumen disposed adjacent the distal end of the body, wherein both the first lumen and second lumen are in fluid communication with the joint lumen. A guidewire has a first end and a second end, and the first end of the guidewire is slidably received in the first lumen and the second end of the guidewire is slidably received in the second lumen.

A method of forming a three-dimensional object is carried out by providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; irradiating the build region through the optically transparent member to form a solid polymer from the polymerizable liquid and advancing the carrier away from the build surface to form the three-dimensional object from the solid polymer, while also concurrently with the irradiating and/or advancing steps: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface, and (ii) continuously maintaining a gradient of polymerization zone between the dead zone and the solid polymer and in contact with each thereof. The gradient of polymerization zone comprises the polymerizable liquid in partially cured form (e.g., so that the formation of fault or cleavage lines between layers of solid polymer in the three-dimensional object is reduced). Apparatus for carrying out the method is also described.
