The Problem

Rectal toxicity stems from the rectum’s proximity to the prostate. It is a highly prevalent complication during prostate cancer radiation therapy. Despite technological advancements and careful and precise treatment planning, prostate movements within or between sessions leave parts of the rectal wall exposed to high radiation doses, which may result in rectal toxicity or proctitis.

The Solution

Hypofractionation and dose escalation are leading treatments for prostate radiation. There is a growing need for a solution to protect the rectum from the high-dose radiation field, significantly reduce rectal toxicity, and pave the way to safer and more cost-effective radiation therapy techniques.

BioProtect Balloon Implant™

BioProtect Balloon spacer is the answer to this need. With its unique design and shape, the balloon provides up to 18mm separation between the rectal wall and the treated area before commencing radiation therapy.

The Implant System

Using a minimally invasive, no-needle insertion device, the balloon is introduced quickly and safely under ultrasound guidance, using a transperineal technique, with local or general anesthesia. Once the balloon is placed between the prostate and the rectum, it is filled with sterile saline and positioned to gain its final well-defined configuration.

The balloon provides reproducible separation between the prostate and rectum. It is visible under all imaging modalities, including CT, MRI, and ultrasound, and by creating a buffer – it enables safe radiation therapy. The balloon maintains its size and shape in the body during the radiation course period and naturally biodegrades over time (usually within six months of implantation), not requiring any additional procedure for removal.

The Procedure

img

Prepare for
Balloon Insertion

  • An Ultrasound guidance probe inserted into the rectum
  • Superficial needle insertion for blunt dissection guidance
img

Perform
Blunt Dissection

  • 6mm incision made at the insertion point
  • Blunt dilator inserted at the peri-rectal space
img

Insert
Ballon Implant

  • Folded balloon inserted via the sheath
  • Saline-filled syringe attached to the BioProtect Balloon system
img

Deploy
Balloon Implant

  • The sheath is retracted, leaving the folded balloon in position
  • Saline fills the BioProtect Balloon, and the balloon is sealed – creating separation necessary to protect healthy tissue from high dose radiation

Treat Prostate while
Protecting Healthy Tissues

  • A course of radiation therapy is performed with minimized risk to OARs
  • No need for spacer removal procedure – balloon biodegrades within six months
