Patent ID: 7998145

Claim:
A locking element for locking a medical device to an elongate member having a central longitudinal axis and a first cross section having a first perimeter and a second cross section having a second perimeter where a portion of the second perimeter is closer to the central longitudinal axis than a portion of the first perimeter, the locking element comprising: a frame defining a central lumen through which a portion of the elongate member fits; one or more levers extending in a second direction from the frame able to be moved between a locking position and a releasing position; and one or more tabs extending in a first direction from the frame able to be moved by the one or more levers between a locked position and a released position; wherein when the locking element is disposed on the elongate member in the second direction from the first cross section, the one or more tabs prevent the locking element from moving in the first direction onto the first cross section when disposed in the locked position and do not prevent the locking element from moving in the first direction onto the first cross section when disposed in the released position; and wherein when the locking element is disposed on the elongate member in the second direction from the first cross section, the levers are closer to the elongate member in the releasing position than in the locking position and the tabs are closer to the elongate member in the locked position than in the released position; wherein the locking element is monolithic.
