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.
