(b) Classification. Class II (special controls). The special controls for this device are:
(1) The premarket notification submission must include methodology and results of the following non-clinical and clinical performance testing:
(i) Biocompatibility testing of the final finished device;
(ii) If provided sterile, sterilization validation;
(iii) If not provided sterile, bioburden testing of the final finished device;
(iv) Shelf life and expiration date validation; and
(v) Performance testing including but not limited to:
(A) Venting mechanism (if device has a vent mechanism);
(B) Safety mechanism(s) to prevent advancement beyond its intended safe placement; and
(C) Structural integrity testing (e.g., tensile strength, balloon leakage and burst strength).
(2) Labeling that includes:
(i) Appropriate warnings and contraindications, including, but not limited to the following statements:
(A) "Do not transport the patient with the rectal balloon inserted. The balloon should be removed prior to transport.";
(B) "Failure to perform the standard imaging position verification protocol may cause the device to not perform as intended.";
(C) "Reduce the rectal balloon fill volume if the patient experiences discomfort due to the rectal balloon inflation."; and
(D) "Do not apply excessive pressure/force on the shaft or tubing of the rectal balloon."
