Brief Summary:
The ProSpace™ System is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of the ProSpace System to reduce the radiation dose delivered to the anterior rectum. ProSpace is a balloon composed of a biodegradable material that maintains that space for the entire course of prostate radiotherapy treatment and is completely absorbed by the patient's body over time.

Condition or disease Intervention/treatment Phase
Prostate Cancer Device: ProSpace Other: Control Not Applicable

Detailed Description:
This study will be a prospective, multi-center, randomized, double-arm, single blind, concurrently controlled study to assess the safety and efficacy of the ProSpace Balloon in prostate cancer subjects undergoing radiotherapy by means of intensity modulation radiation therapy (IMRT).

Primary Outcome Measures :
  1. Adverse Event Rate of Occurrence [ Time Frame: Duration of at least 2 days through 6 months ]
    Rate of occurrence of Grade 1 or greater rectal adverse events and implantation procedure related adverse events through 6 months.

  2. Reduction in Rectal Radiation Exposure [ Time Frame: 6 months ]
    Reduction of at least 25% of the volume of the rectum receiving greater or equal to 70 Gy (VRectum70) when compared to pre-implantation values.
