  • Patent number: 9750532
    Abstract: Access needles and methods of using the needles are set forth in this disclosure. The needles can include a handle and a cannula having a proximal end operatively connected to the handle, a distal end, and a lumen extending through the body of the cannula. A protective sheath may surround the cannula. Further, a stylet may be removably disposed within the lumen of the cannula. The stylet includes a piercing tip at a distal end and a flexible body length extending proximally from the piercing tip to the handle. The flexible body of the stylet provides a path of fluid communication through the lumen of the cannula such that a contrast fluid can effectively pass through the lumen of the cannula. Methods of introducing cannulas to target locations within a body of a patient are also set forth in this disclosure.

  • Patent number: 9662099
    Abstract: A device for sealing an aperture in a tissue includes: an implant configured to seal the aperture when positioned adjacent to the aperture; and a delivery shaft configured to engage the implant to allow the implant to be maneuvered into sealing engagement with a distal surface of the tissue, the delivery shaft comprising a retaining sleeve comprising a locking projection engagable with the locking recess of the implant to secure the implant to the delivery shaft, and a release sleeve axially slideable relative to the retaining sleeve between a first axial position in which the release sleeve is configured to maintain locking engagement between the locking recess and the locking projection, and a second axial position in which the release sleeve permits the locking projection to disengage the locking recess.

  • Publication number: 20160051239
    Abstract: A device for closing an opening in a tissue includes a closure body, a fastening element, and a capture strip coupleable to the closure body such that the capture strip is moveable from a first position to a second position relative to the closure body, the capture strip including a receptacle configured to receive the fastening element when the capture strip is in the first position such that movement of the capture strip from the first position to the second position causes the fastening element to urge the closure body toward the tissue.

  • Patent number: 6755488
    Abstract: A vehicle brakes traction control system and method of operation, for a vehicle having a drive axle with a differential operable between wheels at the two ends of the axle, and brakes for each respective wheel operable by a brake controller. The traction control system includes wheel speed sensors sensing the rotational speed of the wheels, an engine torque demand sensor and an engine torque output monitor. The brake system controller receives signals from the wheel speed sensors, the engine torque demand sensor and the engine torque output monitor to apply the brakes to equalize the rotational speed of the wheels if the engine torque output is less than a desired torque output for a given torque demand.

  • Patent number: 6505894
    Abstract: In a vehicle braking system with electronic brake distribution the threshold level of slip of the rear wheels is increased when the front brake temperature is estimated to have increased to a level where brake fade will occur. This allows more braking torque to be applied to the rear wheels to counteract the brake fade at the front wheels. This increase in threshold slip is, however, overridden if the vehicle is cornering, as detected by a lateral accelerometer or a wheel speed difference across the vehicle, to avoid a reduction in vehicle stability during cornering.
