  • Publication number: 20200391016
    Abstract: Methods and techniques are disclosed for performing transcatheter procedures on a patient that result in similar blood flow changes to the surgical Blalock-Taussig procedure, the Glenn procedure, and the Fontan procedure. Since these transcatheter procedures do not necessarily involve open chest surgery, they tend to be less traumatic for the patient, quicker and easier to perform, and may result in better patient outcomes.

  • Publication number: 20200187945
    Abstract: Methods and devices for increasing oxygenation levels in the blood supply and thereby treating the condition of hypoxemia. Multiple approaches such as pressure reduction in the pulmonary circulatory system, reducing triggering mechanisms in the main pulmonary artery and restricting flow in the pulmonary circulatory system are disclosed. Interventions associated with those approaches can including shunting, restrictors, compliance devices, pharmacologic substances, etc.

  • Publication number: 20200085600
    Abstract: Devices and methods of treating conditions cause or exacerbated by excessive fluid pressures or retentions, such as pulmonary hypertension, that involves shunting excessive fluid pressure from one bodily chamber or vessel to another bodily chamber or vessel.

  • Publication number: 20200054867
    Abstract: Devices and methods of treating fluid retention caused by congestive heart failure or other conditions resulting in edema, lymphoedema, or significant fluid retention (e.g., deep vein thrombosis, cellulitis, venous stasis insufficiency, or damage to the lymphatic network) are described. Specifically, a treatment device is used to create a passage or cannula between the lymphatic system (or other area of the body) and an external drainage device. This device can be only temporarily located in the patient or can be implanted within the patient for longer periods of time. The physician can safely and reliably remove excess fluid from the body via the device and optionally inject other treatment agents.

  • Publication number: 20200032939
    Abstract: The invention relates to a fluid coupling (1) with tolerance compensation for the flexible connection of two media-conducting elements. The invention was based on the object of improving a fluid coupling (1) of the described type in such a manner that the use of complicated latching systems for transport can be omitted. This object is achieved in that the fluid coupling (1) has at least one transport securing device (8, 12), by means of which a separation of the components (2, 3) of the fluid coupling (1) from one another prior to installation can be prevented.

  • Patent number: 9636223
    Abstract: The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valveā€”i.e., the mitral valve and the tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. Finally, there is a proximal anchoring feature to fix the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.

  • Publication number: 20100321021
    Abstract: An excavation apparatus for locating and separating an object from a medium comprising a handle, an excavation tool, a metal detector circuit, at least one coil connected to the metal detector circuit, and at least one output signal device connected to the metal detector circuit. The handle and the excavation tool share a unitary structure. The metal detector circuit is disposed within the handle, and has the at least one coil disposed inside of the excavation tool configured to produce a search field around the excavation tool from within the excavation tool, and the metal detector circuit is configured to notify user with the at least one output signal device when a metallic object is in proximity of the search field.
