Procedure
The biodegradable BioProtect Balloon spacer is deployed in a quick and minimally invasive procedure using a unique, blunted tip insertion device, enabling delivery of the balloon into its optimal position.
The procedure is performed under local or general anesthesia and guided by trans-rectal ultrasound. Once the balloon is in situ, it is inflated with sterile saline to reach the desired final space and sealed in place. The balloon implant remains inflated during the treatment and is absorbed over time.

The balloon is made of medical-grade Poly (L-lactide-co-ε-caprolactone), a biodegradable polymer commonly used in medical devices. It is filled with sterile saline during the procedure, presenting no risk of foreign materials into the bloodstream.
The balloon is 48mm long and 35mm wide and may provide a space of up to 1.8cm.
The balloon remains inflated during radiation treatment and is absorbed over time, therefore, it does not require additional procedures for removal.
It usually takes 6 months to substantial absorption.
You can use general, regional-epidural, or local anesthesia, with or without sedation anesthesia.
The balloon can be easily repositioned before final sealing. Fully deflate the balloon before repositioning, then safely relocate the balloon to your ideal desired position.

Hydrodissection is not mandatory. However, If tissue resistance is noticed, hydrodissection is optional using a slim tip syringe.
