Evaluating the Safety and Performance of the Eight Medical Hyperthermia System IV 1.0 for HIVEC in NMIBC.

The goal of this clinical trial is to evaluate the safety and performance of the Eight Medical Hyperthermia System IV 1.0 when used to deliver recirculating hyperthermic intravesical chemotherapy (HIVEC) with mitomycin C (MMC) in adult patients with non-muscle invasive bladder cancer (NMIBC). The main questions it aims to answer are: * Is the Eight Medical Hyperthermia System IV 1.0 safe when used to deliver HIVEC with MMC in adult patients with NMIBC? * Does the Eight Medical Hyperthermia System IV 1.0 perform as intended by successfully delivering HIVEC with MMC? Participants will: * Receive HIVEC treatment with MMC using the Eight Medical Hyperthermia System IV 1.0 according to the study treatment schedule. * Attend scheduled study visits for safety assessments, clinical evaluations, and follow-up.
