The present invention comprises the provision and use of a novel endoscopic device which is capable of stabilizing, straightening, expanding and/or flattening the side wall of a body lumen and/or body cavity so as to better present the side wall tissue for examination and/or treatment during an endoscopic procedure. The present invention also comprises the provision and use of a novel endoscopic device capable of steadying and/or stabilizing the distal tips and/or working ends of instruments inserted into a body lumen and/or body cavity, whereby to facilitate the use of those instruments.

Method and apparatus for stabilizing, straightening, expanding and/or flattening the side wall of a body lumen and/or body cavity so as to provide increased visualization of the same and/or increased access to the same, and/or for stabilizing instruments relative to the same

An expandable substantially spherical structure for deployment in a blood vessel or other body lumen, comprising: an open frame formed out of a closed loop of filament and configured to assume (i) a collapsed configuration in the form of a substantially two-dimensional elongated loop structure so as to facilitate insertion into the blood vessel or other body lumen, and (ii) an expanded configuration in the form of a three-dimensional substantially spherical structure so as to facilitate retention at a site in the blood vessel or other body lumen; and a flow-restricting face carried by the open frame; wherein the open frame is configured so as to permit substantially normal flow therethrough when the open frame is in its expanded configuration, and further wherein the flow-restricting face is configured so as to restrict flow therethrough.

Method and apparatus for restricting flow through an opening in the side wall of a body lumen, and/or for reinforcing a weakness in the side wall of a body lumen, while still maintaining substantially normal flow through the body lumen

A method for making a device for causing thrombosis of an aneurysm, wherein said device comprises a single elastic filament configurable between (i) an elongated, substantially linear configuration, and (ii) a longitudinally-contracted, substantially three-dimensional configuration, said method comprising:

A method for treating rectal prolapse, the method comprising: inserting a rectum-gripping and advancement apparatus into a prolapsed rectum via the anus; maneuvering the rectum-gripping and advancement apparatus so that the rectum-gripping and advancement apparatus securely engages the rectum; advancing the rectum-gripping and advancement apparatus distally so as to return the prolapsed rectum to its normal, non-prolapsed state; and securing the rectum to supporting tissue whereby to retain the rectum in its normal, non-prolapsed state.

Method and apparatus for endoscopically treating rectal prolapse

A device comprising a single closed loop of elastic filament configurable between (i) a first configuration for movement along a blood vessel; and (ii) a second configuration for lodging within a blood vessel, the second configuration providing a single flow-restricting face sized and configured to cover the mouth of the aneurysm and obstruct blood flow to the aneurysm while permitting substantially normal blood flow through the blood vessel, with the degree of obstruction at the mouth of the aneurysm being such that the aneurysm thromboses when the face is positioned over the aneurysm, the flow-restricting face comprising a plurality of lengths of the closed loop of filament disposed in close proximity to one another in a switchback configuration, and at least one leg for holding the flow-restricting face adjacent the mouth of the aneurysm, the leg configured so as to maintain substantially normal blood flow through the blood vessel.

Method and apparatus for restricting flow through an opening in the side wall

An expandable substantially spherical structure for deployment in a blood vessel or other body lumen, comprising:
