The disclosure provides for a device and method for dilation. The dilation device may include a catheter body having a proximal portion and a distal portion, a dilation expandable body in fluid communication with a first opening on the distal portion of the catheter body, and an occlusion anchor expandable body in fluid communication with a second opening on the distal portion of the catheter body. The method for dilating a stricture site may include inserting the dilation device into a stricture site of a patient, expanding the occlusion anchor expandable body at the stricture site, and expanding the dilation expandable body at the stricture site.

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.

The disclosure relates to devices and methods for the treatment of edema that uses an impeller with a balloon that may be mounted on the impeller housing. The invention provides devices and methods for treatment of edema that use an indwelling catheter with an impeller to lower pressure at an outlet of a lymphatic duct and a balloon on the impeller to guide and to restrict blood flow. The balloon restricts return flow from the jugular and guides that flow into the impeller cage. By funneling the flow into the impeller cage, a rate of flow down the vessel may be increased, resulting in a lateral pressure decrease effecting the lymphatic outlet. Because the lymphatic outlet is subject to a pressure decrease, fluids in the lymphatic system drain to the outlet and into the circulatory system.

In a method embodiment, an example method for simultaneously filling balloons with water, using an apparatus sufficiently compact to be operated while being held by hand, is disclosed. The method includes attaching the apparatus to a water supply. The apparatus includes a fitting comprising an inlet configured to connect to the water supply and a bulkhead joining the at least three branch assemblies. Each branch assembly includes a tube and an automatically-sealing balloon with a neck disposed around and removably attached to the tube. The method further includes simultaneously providing water from the attached water supply to each balloon of the balloon-filling apparatus. The method further includes detaching one or more of the balloons from the balloon-filling apparatus using a force comprising gravity each detached balloon and the water contained therein. Each detached balloon automatically seals upon detachment.

Systems and methods for localized drug delivery via undulating drug coated balloons (DCB), in particular using functionalized nanoparticles as a drug delivery medium in combination with an undulating balloon, are disclosed. In various disclosed embodiments, a nanoparticle matrix is adhered to in an external substrate-surface, such as the balloon surface, and is activated for release once at the treatment site. Activation for release may be enhanced through the use of an undulating balloon system including methodologies for precise control of timing, waveform and extent of undulations.

The balloon catheter of the present invention is provided with a balloon base at a front end of a tubular catheter body having a predetermined length. The balloon base includes a cylindrical base having a larger diameter than an outer diameter of the catheter body, and a lumen having substantially the same diameter as the outer diameter of the catheter body is formed on the base over an entire length with both ends opened. A central axis of the lumen is inclined at a predetermined angle with respect to a central axis of the base concentric with a central axis of the catheter body, and an outer peripheral surface is formed in parallel with the central axis of the base. The balloon is provided on the outer peripheral surface of the parallel base to obliquely inflate with respect to the central axis of the catheter body during inflation.

A balloon catheter and methods for use are disclosed for endovascular procedures, e.g., performing a thrombectomy. In one embodiment, among others, the balloon catheter includes an elongated catheter body. At a distal end, the catheter body also includes an angled tip and a balloon adjacent to the angled tip. The balloon is inflatable to form an oblong shape.

The invention relates to a balloon catheter, in particular for the widening of stents in fenestrations and for T-branch protheses, being provided with a balloon (4), a supply line in the catheter (2) leading to the balloon (4), which allows the balloon (4) to be pressurized, and a central lumen (3) for a guidewire, with the balloon (4) in the expanded state having at least two areas (P, D, M) of different diameter, with these areas merging into one another by forming a step.

A balloon guiding sheath may include an elongated sheath comprising a proximal end, a distal end, an inner tube, an outer tube surrounding the inner tube, an access port, a distal port, and a working lumen extending through an interior portion of the elongated sheath between the access port and the distal port. The balloon guiding sheath may also include an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end. The balloon guiding sheath may include a plurality of inflation holes extending through a side wall of the elongated sheath. The elongated sheath may be sized and configured to enable direct insertion into a patient's vasculature through an arteriotomy in at least one of a femoral artery and vertebral artery to position the inflatable balloon at a target site.
