Innovation in Spacing

The BioProtect difference.

Uniform Space Creation

BioProtect has been shown to create symmetrical and reproducible prostrate-rectum separation, with consistent base-to-apex coverage.1,2,4

SBRT-Grade Protection

Clinical studies demonstrate significant rectal dose reduction and support use of BioProtect in advanced planning, including moderate hypofractionation and SBRT.1,2

Quality of Life Preservation

Patient-reported data demonstrate maintenance of bowel, urinary, and sexual quality of life, supported by reduced physician-reported rectal toxicities.3*

Spacing Performance for Advanced Treatments

Product Overview
10–18 mm

of uniform space creation, with anterior-posterior spacing that was significantly greater at apex, mid-gland, and base than gel spacers.1,4

>84% reduction

in rV70 dose versus control in moderate hypofractionation,1 with consistent dose-lowering effects in conventional and SBRT plans.2

48 months

of post-treatment patient quality of life preservation across the bowel, urinary, and sexual domains.3*

Peer Perspectives

Hear what physicians say about BioProtect.

“Mitigating injury matters and mitigating risk matters, and it’s an additional tool in our toolbox to ensure that the radiation goes only where you need it, which is to the cancer and the organ that harbors the cancer.“

Jonathan Tward, M.D., Ph.D.
Radiation Oncologist

“Because of that reliable contour of the balloon, you’re able to achieve a clear lift, from base to apex, from right to left gland, to give whole gland coverage and protection.“

Dean Laganosky, M.D.
Urologist

“Because the BioProtect Balloon is pre-formed, you get a highly consistent and reproducible shape. The symmetry and space creation have a meaningful impact on dosimetry, decreasing dose not only to the rectum, but also to surrounding tissues, including the penile bulb. That level of control is what we’re aiming for in radiotherapy.“

Shawn Zimberg, M.D.
Radiation Oncologist
