Benefits of technology

[0030]The device can further comprise an expanding element. The expanding element can be configured to minimize migration of fluid delivered to tissue. For example, the expanding element can comprise a balloon. The expanding element can comprise a first balloon and a second balloon where the at least one fluid delivery element is positioned between the first and the second balloon. The expanding element can comprise a tapered profile. The expanding element can comprise a dog-bone profile. The expanding element can comprise at least one recess. The at least one fluid delivery element can be configured to be positioned and / or advanced in the at least one recess. A vacuum port can be positioned in the at least one recess.

Problems solved by technology

However, the current devices, systems and methods for expanding submucosal and other tissue layers are cumbersome, inaccurate, and have a limited effected tissue area.

Embodiment Construction

[0091]Reference will now be made in detail to the present embodiments of the inventive concepts, examples of which are illustrated in the accompanying drawings. Wherever practical, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0092]It is an object of the present inventive concepts to provide devices, systems, and methods to safely and effectively expand an area of tissue, such as one or more layers of a portion of tubular or solid tissue, such as tissue of an organ or tissue of the gastrointestinal tract of a patient. The devices and systems of the present inventive concepts include one or more fluid delivery elements, such as needles or water jets configured to deliver one or more fluids to the tissue to be expanded. Needles may comprise hollow or partially hollow needles, such as needles with one or more openings at the distal end and / or at a side wall location. One or more visualization assemblies may be included, such as to a...

Abstract

A device for expanding tissue comprises at least one fluid delivery tube and at least one fluid delivery element in fluid communication with the at least one fluid delivery tube. The at least one fluid delivery tube comprises a proximal end, a distal end, and a lumen therebetween. The device is constructed and arranged to perform a near full circumferential expansion of luminal wall tissue. Systems and methods are also provided, including a system for expanding tissue layers and treating tissue proximate to the expanded tissue layers.
