  • Patent number: 10660646
    Abstract: A medical flow restrictor that may be used to exclude a saccular aneurysm from the circulatory system. The device, a thin walled, foil-like shell, is compacted for delivery. The invention includes the device, electroforming fabrication methods, delivery assemblies, and methods of placing, and using, the device. A device with an aneurysm lobe and an artery lobe self-aligns its waist at the neck of an aneurysm as the device shell is pressure expanded. Negative pressure is used to collapse both the aneurysm lobe and the artery lobe, captivating the neck of the aneurysm and securing the device. The device works for aneurysms at bifurcations and aneurysms near side-branch arteries. The device, unlike endovascular coiling, excludes the weak neck of the aneurysm from circulation, while leaving the aneurysm relatively empty. Unlike stent-based exclusion, the device does not block perforator arteries. This exclusion device can also limit flow through body lumens or orifices.

    Abstract: Systems and methods for treating eating disorders using electro-physiologically active transducer intragastric balloon system (“EAT system”) are described herein. The EAT System includes an intragastric balloon that is configured to operate in a typical fashion and further modified to include an integrated electro-physiological stimulation unit. The stimulation unit is configured to generate impulses using a transducer that are suitable for stimulating sensory receptors located around the stomach. In particular, transducer transmits mechanical waves through the fluid within the IG balloon and its outer shell to any receptors of the vagus nerve system that are located in the vicinity of the IG balloon. Controlled stimulation of the vagus nerve fibers using the stimulation unit can effectively produce appetite controlling sensations of satiety beyond the typical efficacy period of an unmodified IG balloon.

  • Patent number: 10272229
    Abstract: Embodiments of the present invention are directed to a rigid connector which joins an inflation lumen to an inflatable element in a medical device. The connector comprises a shaft fluidly connected to a crossbar. Preferably one embodiment provides a stable junction through which an inflation fluid may pass and inflate an inflatable element which is not co-linear with the axis of inflation. The junction maintains a generally rigid, fixed angle in relation to the axis of the inflation lumen, which in many embodiments is perpendicular to said axis. This fixed orientation creates a robust structure which is resistant to deflection when forces are encountered during its use within tubular and non-tubular structures within the human body. Such a structure maintains a rigid orientation between the inflatable element and the catheter body.

  • Patent number: 9480826
    Abstract: A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty. An intravascular device can comprise a carrier configured for expansion within a vessel. The carrier can have a s plurality of ribbon strips extending longitudinally between a first end and a second end. An open slot can be positioned between adjacent ribbon strips. A plurality of spikes can be positioned on each of the ribbon strips. The spikes can act as serrations for forming cleavage lines or planes in plaque in the vessel. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment can enables subsequent angioplasty to be performed at low balloon pressures, can reduces dissections, and avoids injury to the arterial wall.

  • Patent number: 8888741
    Abstract: A balloon catheter comprises an outer shaft having a distal end, an inner shaft situated therein to form an annular fluid line and projecting beyond the distal end of the outer shaft, and a balloon which is dilatable under the influence of a fluid introduced through the fluid line under pressure. At its proximal end the balloon is attached in a fluid-tight manner to the distal end region of the outer shaft at a first attachment zone, and at its distal end is attached in a fluid-tight manner to the distal end region of the inner shaft at a second attachment zone. Between the attachment zones, in the undilated state the balloon is placed in longitudinal folds along its length. The balloon, at least at its distal end, has an untapered design with a thin wall thickness (d) which is essentially unchanged over the length of the balloon, and the longitudinal folds extend into the attachment zone at that location.

  • Publication number: 20140213969
    Abstract: A flexible expandable inter vivos tube includes at least one arched segmented portion, a corresponding movable element and at least one positioning mechanism. The at least one arched segmented portion and corresponding movable element forming a flexible closed longitudinally expandable tube. The at least one arched segment includes an H-shaped connector having at least one cavity that allows variable slidable movement of a free end portion of the corresponding movable element. To move one or more of the movable elements of the expandable tube, which are within a cavity of the “H”-shaped connector, a fluid or air is introduced into the H-shaped connector running along the longitudinal axis of the flexible expandable inter vivos tube, so that the hydraulic or air pressure within an inner rib of the H-shaped connector expands the movable elements and, thus, the circumference and diameter of the flexible inter vivos tube are increased.
