20090204069Balloon Catheter - The present invention is primarily directed to a rapid exchange catheter that permits axial movement of an inner conduit within an outer conduit comprising: • an outer conduit; • an inner conduit, suitable for total or partial passage over a guide wire, wherein said inner conduit is movably disposed within the lumen of said outer conduit, wherein the proximal end of said inner conduit is angled such that it pierces the wall of said outer conduit; • means for permitting axial movement of said inner conduit within said outer conduit, such that said movement is not hindered by the passage of the angled proximal part of the inner conduit through said outer conduit; and • means, situated at the proximal end of the outer conduit, for causing axial pushing-pulling movements of said inner conduit.08-13-2009
20090247945BALLOONS AND BALLOON CATHETER SYSTEMS FOR TREATING VASCULAR OCCLUSIONS - A balloon catheter system for the intraluminal advancement of conventional guidewires beyond partially or fully occluded or stenosed lesions in body passages, such as CTOs in the vasculature, is provided. Balloons are provided. In certain embodiments of the invention, a balloon having relatively thickened proximal tapers is provided. In certain embodiments of the invention, balloons having a tapered midsection are provided. The balloons are preferably useful with crossing balloon catheter systems. In certain embodiments of the invention, the balloons preferably reduce or minimize trauma to the vascular wall or wall of other body passage in which it is used.10-01-2009
20090254114BALLOON CATHETER SYSTEM FOR TREATING VASCULAR OCCLUSIONS - The present invention provides a balloon catheter comprising: 10-08-2009
20090287231FLOATING GASTROINTESTINAL ANCHOR - Apparatus (11-19-2009
20100016792COLLECTING SHEATH AND METHOD OF USE THEREOF - The present invention is directed to a device and method for safely removing matter collected by a matter collecting catheter from body organ or internal passage by means of a collecting sheath comprising an elongated tube having at a distal end thereof a deformable container sleeve, a main lumen passing therealong, said lumen being suitable for the passage of the matter collecting catheter through said elongated tube and said deformable container sleeve, and a secondary lumen passing along the walls of said elongated tube and said deformable container sleeve, wherein said secondary lumen terminates in a distal opening near a distal opening of said deformable container sleeve such that a distal end portion of a wire passed through said secondary lumen may be adapted to close said distal opening of said deformable container sleeve by proximal retraction of said wire.01-21-2010
20100016834Device, system, and method for releasing substances in a body cavity - An implantable device for releasing one or more substances into a body cavity such as a urinary bladder, is provided. The device includes an inner balloon located within an outer balloon so as to define a lumen between the outer and inner balloons. The interior of the inner balloon is in fluid contact with an exterior surface of the device, for example via one or more conduits passing through the lumen between the two balloons. A first valve is used for filling the lumen; and a second valve is used for filling the inner balloon. The device is delivered to the body using a delivery catheter. The inner balloon is filled with the substance or substances to be released into the body cavity. The outer balloon is filled with a substance that is chosen to impart a desired specific gravity to the device. The substances to be released may be contained in particles coated with a soluble coating. The particles may be in suspension or embedded in a matrix.01-21-2010
20100016871FLOATING GASTROINTESTINAL ANCHOR - Apparatus for use in a gastrointestinal tract of a subject, the apparatus including a straightening rod (01-21-2010
20100022970COLLECTING SHEATH AND METHOD OF USE THEREOF - The present invention is directed to a device and method for safely removing matter collected by matter collecting catheter from a body organ or passage by means of a collecting sheath comprising an elongated tube having at its distal end an expandable container sleeve, and a lumen passing along said elongated tube and said expandable container sleeve, wherein said lumen is suitable for passage of the matter collecting catheter therethrough. The expandable container sleeve may be introduced into the body organ or passage in a folded state for reducing its cross-sectional area.01-28-2010
20100114022SPIRAL BALLOON CATHETER - The present invention provides a balloon catheter system comprising one or more conduits to which are attached a compliant balloon having a non-helical shape in its deflated state, wherein said balloon is constructed such that is capable of adopting a spiral or helical conformation upon inflation. In addition, the present invention also provides methods for using said balloon catheter system.05-06-2010
20100121371NON-ENDOSCOPIC INSERTION AND REMOVAL OF A DEVICE - Apparatus is provided for use in a stomach of a subject, including a gastric balloon and a hollow, flexible tube coupled at a distal end thereof to the gastric balloon. A proximal portion of the tube, when in a relaxed position, is shaped so as to prevent the balloon from passing into a duodenum of the subject. The apparatus also includes an inflation conduit disposed in part within the distal end of the tube, the inflation conduit exiting the tube at a site proximal to the gastric balloon. Other embodiments are also provided.05-13-2010
20100137793SPIRAL BALLOON CATHETER - The present invention provides a balloon catheter system comprising one or more conduits to which are attached an inner compliant balloon having a non-helical shape in its deflated state, said balloon being enclosed by an outer non-compliant or semi-compliant balloon, wherein the inner balloon is constructed such that upon inflation, said inner balloon is capable of adopting a spiral or helical conformation. The present invention also provides methods for using said balloon catheter system.06-03-2010
20100262124SPIRAL BALLOON CATHETER - The present invention provides a balloon catheter system comprising one or more conduits to which are attached a compliant balloon having a non-helical shape in its deflated state, wherein said balloon is constructed such that is capable of adopting a spiral or helical conformation upon inflation. In addition, the present invention also provides methods for using said balloon catheter system.10-14-2010
20110040365CATHETER - A system comprising a catheter having an expandable element, which when expanded, has an annular shape surrounding a passageway. The expandable element in the expanded state is rollable along at least a portion of the shaft of the catheter without slipping. The system may be used for delivering an object to a site in the body, retrieving an object from a body, removing debris and/or other particulate matter from a blood vessel, and distending and/or expanding a pathologically-involved region of a blood vessel wall.02-17-2011
20110092998BALLOON HYDRAULIC AND GASEOUS EXPANSION SYSTEM - Apparatus is provided, including an intrabody balloon configured to be in a folded state during insertion into a subject's body, and to become inflated inside the subject's body. The apparatus also includes one or more bands disposed annularly around the balloon at respective longitudinal positions along the balloon. The bands are configured, while the balloon is in the folded state thereof, to secure the balloon in the folded state, and due to the balloon becoming inflated, to slide and become coupled to a portion of the apparatus. Other applications are also described.04-21-2011
