  • Patent number: 11937838
    Abstract: A device and method for intravascular treatment of an embolism, and particularly a pulmonary embolism, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member having a plurality of first clot engagement members and second clot engagement members positioned about the circumference of a distal portion of the support member. In an undeployed state, individual first clot engagement members can be linear and have a first length, and individual second clot engagement members can be linear and have a second length that is less than the first length. The clot engagement members can be configured to penetrate clot material along an arcuate path and hold clot material to the clot treatment device.

  • Patent number: 11918243
    Abstract: Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient.

  • Patent number: 9862119
    Abstract: Molding equipment comprising a mold having at least one cavity is disclosed. Each cavity allows the formation of a brick. A brick molding element is installed on top of each cavity to allow the formation of a mortise interlock element. The brick molding element is typically secured in place by mean of a securing mechanism. The molding equipment may be used for molding a variety of inter-engaging stackable brick element.

  • Patent number: 7851178
    Abstract: The present invention relates to a method of evaluating the efficiency of sterilization processes by measurement of degradation level of prion protein indicators. When exposed to sterilization conditions, prion indicators are degraded in a manner to proportionally indicate the level of degradation of prion proteins themselves on medical devices or other surfaces usable in surgery and health cares.

  • Patent number: 6605788
    Abstract: An air-insulated high-voltage disconnector including a pivotally-mounted arm suitable for pivoting at one of its ends about a horizontal axis that is perpendicular to the axis &Dgr; of the arm, and also suitable for turning about its own axis &Dgr;, the free end of the arm carrying a contact part or “hammer” which, when the disconnector is in the closed position, co-operates with a jaw comprising a jaw support to which two facing rows of contact fingers are fixed, wherein the hammer is equipped with contact tabs co-operating with the contact fingers, each contact tab forming a wedge of angle &bgr;, which wedge acts, during disconnector closure, to meet the corresponding row of fingers with an angle of attack &agr;, said angle of attack &agr; being less than 90°.

  • Patent number: 6570117
    Abstract: An air-insulated high-voltage disconnector includes a pivoting arm which pivots at one end about a horizontal axis perpendicular to the axis of the arm and turns about its axis. The free end of the arm carries a contact member referred to as the hammer cooperating, in the closed position of the disconnector, with a jaw including a jaw support to which are fixed two facing rows of contact fingers. The contact fingers are tubular and open at both ends.
