Patent ID: 7766208

Claim:
A closure device for an arteriotomy comprising: an elongate hollow shaft and an elongate driver slidably disposed therein; a pair of opposing first and second actuation tips disposed at a distal end of the shaft and defining a staple chamber there between; a first anvil disposed within the staple chamber and coupled to the first actuation tip; a second anvil disposed within the staple chamber and coupled to the second actuation tip; a staple at least partially disposed within the staple chamber, the staple having a pair of opposing staple legs coupled by a bend at a proximal end of the staple, each staple leg having an expansion ramp extending toward the opposite staple leg and longitudinally slidable along the first anvil to open the staple when the driver pushes the staple distally within the staple chamber; a deployment configuration wherein the first and second anvils mate with each other to substantially span the staple chamber for retaining and deforming the staple therein; a release configuration wherein the first and second actuation tips are spread apart to provide a gap between the first and second anvils, the gap dimensioned such that the staple may pass there through; and a release mechanism for transforming the closure device from the deployment configuration to the release configuration.
