Patent ID: 8603137

Claim:
A method of establishing hemostasis relative to a puncture in a body lumen wall, comprising: positioning a closure device in a distal end of a deployment device; positioning the closure device in a tissue tract in proximity with the puncture in the body lumen wall with the deployment device, the closure device including a distal portion and a proximal portion, the closure device including a central longitudinal axis and a biasing member coupling the proximal portion and the distal portion; moving tissue engagement features associated with the distal portion into engagement with a proximal surface of the body lumen wall; after moving the tissue engagement features associated with the distal portion into engagement with the proximal surface of the body lumen wall, actuating the deployment device to establish relative rotation between the distal portion and the proximal portion of the closure device about the central longitudinal axis to establish hemostasis relative to the puncture, the actuating the deployment device including releasing the biasing member to allow the biasing member to move from a pre-deployed state to a deployed state; and deploying the closure device.
