  • Patent number: 10130475
    Abstract: A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a surgical delivery instrument, a valve repair device, and a paddle control mechanism. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to attach to a native valve of a patient. The valve repair device includes a first paddle, a second paddle, and a pair of gripping members. The first and second paddles are movable between an open position and a closed position. The paddles and the gripping members are configured to attach to the native valve of the patient. The paddle control mechanism is configured to move the first and second paddles independently of each other.

  • Patent number: 10130282
    Abstract: Verification that an implantable medical system within a patient is MRI safe is provided. Several verifications may be performed such as verifying that the device and leads are of an MRI safe type, that the leads have adequate electrical integrity, that the device has entered an MRI safe mode, that the lead routing and device placement are MRI safe, and that the MRI settings of the MRI machine are safe for the implantable medical system. The result of these verifications may lead to a conclusion that the implantable medical system of interest is or is not MRI safe for a given MRI scan. An indication of this result may be output such as via a display so that an MRI technician can have some assurance as to whether to conduct the MRI scan.

  • Patent number: 10111751
    Abstract: A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are movable between an open position and a closed position. Each of the gripping members has a barbed portion for securing the gripping members to the native valve of a patient. Each gripping member is slidably attached to a corresponding paddle. Each gripping member can be moved in a first direction along the paddle before the barbed portion of the gripping member pierces the native valve of the patient. Each gripping member can be moved in a direction substantially opposite the first direction after the barbed portion pierces the native valve of the patient such that the gripping members create a tensioning force on the native valve of the patient.

  • Patent number: 9743584
    Abstract: The mower blade system provides one or more blades, preferably two, secured to a housing that is attached to the mower. The blades provide a cutting edge that is sharpened for mowing the yard, lawn, field, or other area. The blade attaches to an attachment arm via a locking body and retention body. A pivot aperture of the blade is placed upon a pivot finger of the attachment arm that secures the blade on the attachment arm. The locking body abuts the pivot finger to secure the blade on the pivot finger. The retention body then slides over the locking body to further secure the blade on the pivot finger.

  • Patent number: 9689374
    Abstract: An adjustable lift regulating device (30, 32, 40, 50, 52, 56, 60, 68, 72, 76) on an inboard portion of a wind turbine blade (28). The lift regulating device is activated to reduce lift on the inboard portion of the blade by causing flow separation (41) on the suction side (22) of the blade. To compensate for the lost lift, the blade pitch is increased to a running pitch that facilitates stalling on the outer portion of the blade in gusts. This provides passive reduction of fatigue and extreme loads from gusts while allowing full power production under non-gust conditions.

  • Publication number: 20170159297
    Abstract: Devices, systems and methods for providing a retrofit and repair technique and device for asphalt shingle roof coverings or roofing systems that exhibit premature adhesive tab seal failures. A device can have a handle at one end and a blade tip end at the other end has the blade tip inserted under a shingle to be repaired. The device can dispense a row of “dabs” at a selected location under roof shingle(s). The dispenser can dispense a row of individual “dabs” by a volume container. Alternatively, the dispenser can have a roll with a plurality of rows of pre-made “dabs” of adhesive on removable type paper. Once the blade tip end of the tool device is inserted between upper and lower shingles, the dabs are dispensed by removing the release paper, and the device is pulled out with the release tape is wound up, advancing the adhesive cylinders. Next, the worker can press down on the upper shingle.

  • Patent number: 9420960
    Abstract: Various embodiments concern sensing bioelectrical signals using electrodes along a lead, the electrodes having a spatial configuration along the lead, generating signal data sets, one signal data set being generated for each bioelectrical signal, and graphically representing the electrodes and data representations of the signal data sets on a display. In various embodiments, each data representation indicates a parameter of a respective one of the data sets, the electrodes are graphically represented on the display in a spatial configuration representative of the spatial configuration of the electrodes along the lead, and each data representation is graphically represented on the display in spatial association with at least one electrode through which the bioelectrical signal on which the signal data set is based was sensed. The parameter can be indicative of the relative presence of a biomarker in the bioelectrical signals.

  • Publication number: 20160009005
    Abstract: A method including: curing a casting (18) of a wind turbine blade in a mold (12); and initiating and then stopping a rotation of the mold during the step of curing. By repositioning the mold, a rate of deformation for any given location can be reduced, and previously formed deformations can be decreased in size. In addition, repositioning the mold may be useful to help distribute a curable material (42), such as epoxy resin, throughout a cavity (20) that defines the blade.
