English term or phrase: The Turns to Failure

The Turns to Failure for the XXX （COMPANY NAME）Dilatation Catheter is 141.

SOME BACKGROUND INFO：

Recommendation
FDA recommends that you measure the torque strength of the catheter when the distal tip is not free to rotate, by rotating the proximal end of the catheter until failure. We recommend that you precondition catheters prior to evaluating torque strength by tracking through a tortuous path fixture (as described above in Section 2. Balloon Preparation, Deployment and Retraction). We recommend that you report the number of rotations to failure and the failure mode for each sample tested. Additionally, we recommend that you test the catheter in a fixture that simulates the anatomy of the aortic arch and coronary arteries. We also recommend you provide the clinical basis for your acceptance criteria. We recommend that you report the number of turns to failure in the device labeling.

Chinese translation:失效前旋转次数

Explanation:
这里是指根据扭力原理通过旋动近端以便带动远端。但由于材料疲劳原因，旋转一定次数后则无法再做此操作。
