Apparatus comprising: a sleeve adapted to be slid over the exterior of an endoscope; a proximal balloon secured to the sleeve; an inflation/deflation tube carried by the sleeve and in fluid communication with the interior of the proximal balloon; a push tube slidably mounted to the sleeve; and a distal balloon secured to the distal end of the push tube, the interior of the distal balloon being in fluid communication with the push tube, wherein the distal balloon is capable of assuming a deflated condition and an inflated condition, and further wherein when the distal balloon is in its deflated condition, an axial opening extends therethrough, the axial opening being sized to receive the endoscope therein, and when the distal balloon is in its inflated condition, the axial opening is closed down.

Method and apparatus for manipulating the side wall of a body lumen 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 endoscopic tissue snare system comprising: a sleeve adapted to be slid over the exterior of an endoscope; a pair of push tubes slidably mounted to the sleeve, each of the push tubes comprising a distal opening and a proximal opening; a distal balloon secured to the distal ends of the pair of push tubes; and a snare comprising a pair of free ends and an intermediate portion disposed between the pair of free ends, wherein the snare extends into the proximal opening of one push tube, up the length of the push tube, out the distal opening of that push tube, across the face of the distal balloon, into the distal opening of the other push tube, down the length of that push tube, and out the proximal opening of that push tube.

Method and apparatus for providing increased visualization and manipulation of a body side wall

Apparatus for endoscopically retracting tissue, the apparatus comprising a sleeve adapted to be slid over the exterior of an endoscope; a balloon movably mounted to the sleeve; and at least one connector extending from the balloon and configured to be secured to tissue which is to be retracted; wherein the balloon is configured to be moved relative to the sleeve in order to retract the tissue.

An endoscopic tissue retraction system comprising: an element configured to be movably mounted to an endoscope; and a connector configured to be secured to the element and to the tissue which is to be retracted.

Method and apparatus for manipulating the side wall of a body lumen or body cavity

A mechanical vacuum dressing comprising: a first valve layer comprising a first one-way valve; a second valve layer comprising a second one-way valve; the first valve layer being joined to the second valve layer so as to define a chamber therebetween; the first one-way valve being configured to admit fluid into the chamber through the first one-way valve but prevent fluid from exiting the chamber through the first one-way valve; the second one-way valve being configured to exhaust fluid from the chamber through the second one-way valve but prevent fluid from entering the chamber through the second one-way valve; and the second valve layer comprising an elastomeric material such that (i) when the second valve layer is moved away from the first valve layer, the volume of the chamber is increased, and (ii) when the second valve layer is thereafter released, the second valve layer moves back towards the first valve layer and the volume of the chamber is decreased.

Mechanical vacuum dressing for mechanically managing, protecting and suctioning small incisional wounds

Apparatus comprising: a sleeve adapted to be slid over the exterior of an endoscope; an aft balloon secured to the sleeve; an inflation/deflation tube carried by the sleeve and in fluid communication with the interior of the aft balloon; a pair of hollow push tubes slidably mounted to the sleeve, the pair of hollow push tubes being connected to one another at their distal ends with a raised push tube bridge, the raised push tube bridge being configured to nest an endoscope therein; and a fore balloon secured to the distal ends of the pair of hollow push tubes, the interior of the fore balloon being in fluid communication with the interiors of the pair of hollow push tubes, wherein the fore balloon is capable of assuming a deflated condition and an inflated condition, and further wherein (i) when the fore balloon is in its deflated condition, an axial opening extends therethrough, the axial opening being sized to receive the endoscope therein, and (ii) when the fore balloon is in its inflated condition, the axial opening is closed down.

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

Apparatus for straightening and flattening a side wall of a body lumen or body cavity so as to provide three dimensional exposure of an abnormality within the body lumen, and simultaneously providing for the stabilization of the working end of an endoscope or surgical tool, the apparatus comprising a deployable hoop expander comprising a structure defining a volume and being configured so as to be transitionable between a reduced cross-sectional configuration for easy insertion into a body lumen and an expanded cross-sectional configuration for engaging, straightening and flattening the side wall of the body lumen, whereby to provide three dimensional exposure of the abnormality within the body lumen, the deployable hoop expander being configured for simultaneously providing for the docking of the end of the endoscope or other instrument so as to stabilize the same for endoscopic viewing and/or therapy.

Method and apparatus for straightening and flattening the side wall of a body lumen or body cavity so as to provide three dimensional exposure of a lesion or abnormality within the body lumen or body cavity, and/or for stabilizing an instrument relative to the same

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.
