Patent ID: 8308725

Claim:
A device having distal and proximal end portions comprising: an elongated body having a longitudinal axis and an outside diameter, a jaw member positioned at the distal end portion, said jaw member having a stationary arm formed in the body and a pivotable arm coupled to the distal end portion of the body, a pivot point of said pivotable arm being fixed relative to the longitudinal axis, the pivotable arm including a pivot end disposed at the pivot point and a free end distanced from the pivot point, the free end being closer to the proximal portion of the device than the pivot end, a moveable closure sleeve disposed at least partially about the body, said closure sleeve configured to extend to the distal end of the elongated body and also configured such that coaxial movement of the sleeve along the longitudinal axis causes the jaw member to open or close, the closure sleeve terminating at a distal part of the closure sleeve in a closure ring which completely circumscribes the elongated body, the closure ring being urged against a distal part of the pivotal arm to move the pivotal arm toward the stationary arm when the closure sleeve is moved proximally relative to the elongated body; further comprising a spring, said spring biasing the pivotable arm in an open configuration; and wherein the jaw member is positioned in a cavity in the elongated body, said cavity defining an area having a reduced cross sectional area compared to the more proximal portions of the elongated body, wherein the jaw member has a diameter substantially equivalent to the outside diameter of the elongated body when in a closed position.
