  • Patent number: 10835224
    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.

  • Patent number: 8685059
    Abstract: A closure device for sealing a percutaneous puncture in a wall of a body passageway of a living being. In an exemplary embodiment, the closure device includes an anchor configured to be brought into engagement with an interior of the body passageway, a plug including a proximal portion and a distal portion, a filament coupled to the anchor and the plug. The filament may include a first extending section. The closure device further includes a lock attached to the first extending section, wherein the collar is positioned between the lock and the anchor, wherein the lock frictionally engages the first extending section of the filament so that the lock is movable along the filament only in response to application of a force on the lock that overcomes the frictional engagement.
