摘要：
Embodiments of the present disclosure include methods and systems for a catheter assembly including a catheter shaft, a balloon positioned on the catheter shaft, where the balloon has a first balloon waist, a first lead extending longitudinally through the catheter shaft, and a first sealing member adjacent the first balloon waist and coupled to the first lead, where the first lead can provide electrical current to reversibly transition the first sealing member from a nonactivated state to an activated state in response to a temperature change in the first sealing member, and where at least a portion of the balloon rotates relative the catheter shaft in the nonactivated state and the first sealing member engages the first balloon waist to form a fluid tight seal and to prevent rotation of the balloon relative the catheter shaft in the activated state.
