  • Patent number: 10702681
    Abstract: The invention refers to endovascular catheters and methods useful to endovascular surgery. In particular, it refers to support catheters with balloons that are used for the placement or the forwarding of the guidewire through demanding tortuosity and important vascular stenoses in cases where the guidewire needs the best possible backup support of the catheter. This is achieved with the development of an endovascular support catheter with a mobile balloon, which has the ability to move along the body of the catheter, at its distal part. The movement of the balloon is achieved with the use of two mobile external rings, one inner wire circuit, and one control handle which is found at the proximal end of the device. The mobile balloon allows the catheter to move inside the vessel even when it is inflated and basically anchored within the vessel.

  • Patent number: 10327936
    Abstract: An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track. The device may further incorporate tracking and visualization subcomponents, as well as pharmaceutical delivery subcomponents.

  • Publication number: 20150005805
    Abstract: A dilation apparatus comprises an elongate member and a dilation assembly that is slidable along the elongate member. The dilation assembly comprises a platform and an inflatable dilator. The platform and the elongate member cooperate to absorb inflation forces from the dilator directed toward the longitudinal axis of the elongate member, such that the dilation forces are exerted against tissue asymmetrically relative to the longitudinal axis of the elongate member. The dilation apparatus may be used to dilate the ethmoid infundibulum in a human patient. Various devices may be used to maintain the dilated state of an ethmoid infundibulum, including a wedge, a mesh, and a tether. An illuminator may be configured to reach around an uncinate process, retract the uncinate process, and then illuminate the ethmoid infundibulum to provide improved visualization of the ethmoid infundibulum.

  • Patent number: 8915938
    Abstract: A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.

  • Publication number: 20140336694
    Abstract: A set of sinus balloon catheters are provided for treating a patient's paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90° to a proximal segment and a balloon catheter which is substantially straight. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, and/or to dilate sinus cavities to remove them.
