Substantially rigid and stable endoluminal surgical suite for treating a gastrointestinal lesion
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.
1. An endoscopic system, comprising:
a device having:
a first lumen and a second lumen extending along a longitudinal axis of the device;
a chamber associated with a distal portion of the device, at least a portion of the chamber extending beyond a distal end of the device, wherein the chamber is movable from a collapsed position to an expanded position, the chamber comprising a plurality of flexible strips, wherein in the expanded position the chamber has an expanded portion formed by an expanded one of said plurality of flexible strips and an unexpanded portion formed by an unexpanded one of said plurality of flexible strips, a first distance to a highest point of the expanded portion being greater than a second distance to the non-expanded portion to form an altered working space within the body lumen, and wherein the first lumen includes a first opening into the chamber and the second lumen includes a second opening into the chamber; and
a first balloon and a second balloon positioned on opposite ends of the chamber;
a first instrument movable within the first lumen, wherein a distal portion of the first instrument is extendable into the chamber; and
a second instrument movable within the second lumen, wherein a distal portion of the second instrument is extendable into the chamber.
2. The endoscopic system of claim 1 , wherein the first balloon is positioned proximal of the chamber.
3. The endoscopic system of claim 1 , wherein the first balloon is positioned distal of the chamber.
4. The endoscopic system of claim 1 , further comprising a third lumen, extending through the longitudinal axis of the device, and configured to receive an endoscope.
5. The endoscopic system of claim 1 , wherein the first and second openings open into a proximal portion of the chamber.
6. The endoscopic system of claim 1 , wherein a proximal end of the plurality of strips are attached to a proximal cap, and a distal end of the plurality of strips are attached to a distal cap.
7. The endoscopic system of claim 6 , wherein the distal cap includes an opening configured to receive a balloon guide catheter.
8. The endoscopic system of claim 7 , further comprising a balloon guide catheter extending through the distal cap opening, wherein the balloon guide catheter includes a second balloon positioned distal of the distal cap.
9. The endoscopic system of claim 1 , wherein the first balloon only expands on one side of the longitudinal axis of the device.
10. An endoscopic system, comprising:
a device having:
a first portion comprising a handle,
a longitudinal axis,
a distal portion comprising a chamber comprising a plurality of flexible strips, at least a portion of the chamber extending beyond a distal end of the device and moveable between a first collapsed position and a second expanded position, the chamber in the second expanded position having an expanded portion formed by an expanded one of said plurality of flexible strips and an unexpanded portion formed by an unexpanded one of said plurality of flexible strips, a first distance to a highest point of the expanded portion greater than a second distance to a non-expanded portion and form an altered working space within the body lumen,
a first balloon and a second balloon positioned on opposite ends of the chamber, and
a first lumen and a second lumen extending along the device, the first lumen having a first opening into the chamber and the second lumen having a second opening into the chamber, the first lumen configured to receive a first instrument therethrough.
11. The endoscopic system of claim 10 , wherein the chamber forms the altered working space adjacent a target tissue structure when in the second expanded position.
12. The endoscopic system of claim 10 , wherein the first balloon is positioned proximal of the chamber.
13. The endoscopic system of claim 10 , wherein the second first balloon is positioned distal of the chamber.
14. The endoscopic system of claim 10 , further comprising a balloon catheter insertable through the device, wherein the balloon catheter includes a second balloon.
15. The endoscopic system of claim 10 , wherein the chamber has a reduced transverse dimension region between the first and second balloons compared to the first and second balloon when in the second expanded position.
