  • Publication number: 20240293117
    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: 20230157855
    Abstract: A deployment device for lining a vessel having a housing having a proximal end and a distal end opposite the proximal end, the housing defining a guidewire channel, a tube elongated along a longitudinal axis, the tube having a proximal end and a distal end spaced from the proximal end of the tube along the longitudinal axis, a sheath assembly having a hub removably coupled to the distal end of the housing, and a mesh removably coupled to the tube and positioned along the tube. The tube and the sheath assembly are configured to move along the guidewire and into the vessel through a puncture and release the mesh inside the vessel when at least one of the tube and the mesh is actuated.

  • 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.

  • Patent number: 8870917
    Abstract: A deployment instrument for deploying a closure device for sealing a percutaneous puncture in a wall of a body passageway, the deployment instrument including a carrier assembly, wherein the carrier assembly is configured to hold the closure device in a pre-deployment state, and a tensioner assembly, wherein the filament is fixedly attached to the tensioner assembly, wherein the deployment instrument is configured to increase the tension in the filament upon linear movement of the deployment instrument away from the wall of the body passageway when the closure device is anchored to the wall via the anchor such that the tension is gradually increased as the deployment instrument is moved between a first linear distance and a second linear distance greater than the first linear distance from the wall of the body passageway.
