  • Patent number: 10905414
    Abstract: A releasable elongated assembly includes a release member having a length and an opening that extends along the length. The releasable elongated assembly includes a first elongated element having a first coupling member disposed in the opening and a second elongated element having a second coupling member disposed in the opening opposite the first coupling member along the length. The first and second elongated elements are interlaced with each other in the opening at a location between the first coupling member and the second coupling member such that the first and second elongated elements are attached to each other. The release member is moveable from a first position where the first and second coupling members are captured in the opening to a second position where the first and second coupling members are released from the opening so as to detach the first and second elongated elements from each other.

  • Publication number: 20200289101
    Abstract: A closure device system for sealing a percutaneous puncture in a vessel wall can comprise a toggle configured to engage an interior surface of the vessel wall, a plug configured to engage an exterior sur-face of the vessel wall, and a suture that extends through the plug and through the toggle along at least a first direction so as to couple the toggle to the plug. The system can further comprise a tube that extends through the plug and through the toggle along the first direction such that a distal end of the tube is disposed distally to the toggle. The tube can define a guidewire lumen that extends therethrough along the first direction. And the guidewire lumen can be configured to receive a guidewire that protrudes from the vessel wall such that the plug, toggle, and tube are slidable along the guidewire toward the vessel wall.

  • Patent number: 10682128
    Abstract: A vascular closure device includes a deployment assembly, a sealing unit carried by the deployment assembly, and a tamper carried by the deployment assembly and that is disposed along a suture with respect to the sealing unit. The vascular closure device includes a locking assembly coupled to the tamper so as to selectively inhibit advancement of the tamper along the suture in the distal direction toward the sealing unit. The locking assembly is adapted to transition from A) a locked configuration where the tamper is inhibited from sliding along the suture, into B) an unlocked configuration where the tamper is slidable along the suture in the distal direction and into contact with the sealing unit.

  • Publication number: 20200000448
    Abstract: A vascular closure device includes a release component, a delivery component, a sealing device and at least one actuator. The release component is elongate along a longitudinal direction, and defines a distal end and a proximal end. The delivery component extends along the release component such that at least the release component is movable relative to the delivery component. The delivery component includes a delivery tube body and defines a delivery tube channel.

  • Patent number: 10517633
    Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.
