  • Method for anchoring a mitral valve
    Patent number: 9192468
    Abstract: An artificial mitral valve is anchored in the left atrium by placing the valve between the annulus of the natural mitral valve and an artificial annulus. The artificial annulus is formed by inserting a tool into the coronary sinus, and adjusting the tool to force the wall of the left atrium to form an annulus above the artificial valve, this locking it in place and forming a hemostatic seal.

  • MEDICAL DEVICE FOR USE IN BODILY LUMENS, FOR EXAMPLE AN ATRIUM
    Publication number: 20150250539
    Abstract: A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpended configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical members) or inflatable member(s).

  • Apparatus and method for intra-cardiac mapping and ablation
    Patent number: 9119633
    Abstract: An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.

  • Gastric Acid Detector
    Publication number: 20150201870
    Abstract: In medical procedures requiring access to the stomach, such as insertion of a nasogastric tube (also known as NG tube), verification is required that the tube has indeed reached the stomach and did not find its way into another organ such as the lungs. The invention provides a simple and foolproof way of establishing that the stomach was reached. The method does not require any additional training of the medical staff. The invention can be used in conjunction with an NG tube and provides feedback to the user when the NG tube is correctly inserted in the stomach by detecting the presence of Gastric acid.

  • Surgical instrument and method for tensioning and securing a flexible suture
    Patent number: 9023058
    Abstract: A surgical instrument may be used to apply tension to a flexible suture to close and secure a broken or cut bone (e.g. a sternum following a sternotomy). The device preferably applies an adjustable tension to the flexible suture in order to secure the bone together. Multiple instruments may be used together to ensure the desired tension is applied to the entire bone structure being secured with the flexible sutures. Once the desired tension is achieved, the device preferably provides a mechanism to apply a uniform twist to the flexible suture to lock the flexible suture in place and maintain the tension previously achieved. The device may automatically cut the flexible suture, or the flexible suture may be cut by the surgeon once the twisting action has been performed.

Multiple instruments may be used together to ensure the desired tension is applied to the entire bone structure being secured with the flexible sutures. Once the desired tension is achieved, the device preferably provides a mechanism to apply a uniform twist to the flexible suture to lock the flexible suture in place. The instrument preferably decreases the upward tension applied to the flexible sutures over the duration of the application of twisting. The device may automatically cut the flexible suture, or the flexible suture may be cut by the surgeon once the twisting action has been performed.

  • Lithotripsy system with automatic 3D tracking
    Patent number: 8979776
    Abstract: A lithotripsy system capable of 3D tracking monitors the acoustic reflection from the stone in order to focus the shock wave on the stone regardless of shock wave displacement or stone movement. The tracking and focusing is based on a phased array concept, allowing the lithotripsy head to remain stationary and well coupled to the body. An alternate shock wave steering is based on refraction by a variable liquid wedge.

  • Mixing syringe
    Patent number: 8834449
    Abstract: A movable mixing disc is inserted into a regular syringe. The mixing disc has a small hole covered by a fine screen, allowing only saline solution to get behind the disc. When the plunger of the syringe is pressed, the saline solution emerges from the mixing disc hole as a high velocity jet, stirring up the settled particles. As the ejection continues, the mixing disc is pushed forward by the plunger in order to eliminate any unused volume.

  • MIXING SYRINGE
    Publication number: 20140254303
    Abstract: A movable mixing disc may be utilized in connection with a syringe. The mixing disc may comprise a hole which may be covered by a fine screen or coupled to a porous member, allowing only certain elements of a solution to pass through the mixing disc. Actuation of a plunger of the syringe may cause liquid to emerge from the mixing disc hole as a high velocity jet or other turbulent flow, stirring up any settled particles on a distal side of the mixing disc. As the ejection continues, the mixing disc may be pushed forward by the plunger in order to eliminate any unused volume. Also, the mixing disc may be moved forward by virtue of a pressure difference created by a pressure drop across the mixing disc, such as a pressure drop created as the plunger is displaced to induce fluid flow across the mixing disc.
