The BioProtect Balloon Implant 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 BioProtect Balloon Implant System to reduce the radiation dose delivered to the anterior rectum. The BioProtect Balloon Implant System is composed of a balloon made of a biodegradable material that maintains the space for the entire course of prostate radiotherapy treatment and is completely absorbed by the patient's body over time.

The BioProtect Balloon Implant™ System is composed of a single use, biodegradable, inflatable balloon implant, designed to act as a spacer between the prostate and the rectum. The BioProtect Balloon Implant System is supplied sterile. The balloon is implanted transperineally using transrectal ultrasound (TRUS) guidance and remains stable throughout the radiation treatment and gradually degrades over time. The BioProtect Balloon Implant System consists of single use components detailed below: 1. Balloon biodegradable, inflatable balloon acts as a spacer between the prostate and rectal wall. 2. Balloon Deployer delivery system, the balloon is mounted and folded on the deployer 3. Delivery Kit - an applicator system used to position and deploy the balloon in the intended location. It includes an 18-gauge echogenic needle, blunt-tipped tissue dilator, and balloon introducer sheath. The BioProtect Balloon Implant System is for prescription use only.

Barrigel 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 Barrigel to reduce the radiation dose delivered to the anterior rectum. Barrigel is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment and is intended to be absorbed by the patient's body over time.

Barrigel Injectable Gel is a sterile, transparent, biodegradable gel of stabilized hyaluronic acid (HA) at a concentration of 20 mg/mL in phosphate buffered saline. The HA, formulated utilizing Q-Med's patented NASHA™ technology, is produced from non-animal hyaluronic acid by fermentation of Streptococcus species of bacteria. The HA gel is cross-linked with 1,4-butanediol diglycidyl ether (BDDE) under alkaline conditions, thereby creating ether bonds between the HA chains, resulting in a three-dimensional network. The gel is insoluble in water and organic solvents. Barrigel is supplied in a single-use glass syringe, containing 3 mL of product. Each syringe is terminally sterilized by moist heat in a heat-sealed pouch of PET/Tyvek® and packaged in a cardboard carton. Barrigel is intended for use by health-care professionals only and should be stored up to 25° C (77° F). Barrigel is manufactured for Palette Life Sciences by O-Med AB, a subsidiary of Galderma AB. The Barrigel needle is a sterile 18G stainless-steel needle, 20 cm in length, provided with an optional stylet and protected by a polyester sheath which is removed prior to use. The needle is sterilized by radiation and two (2) needles are provided in each heat-sealed pouch of PET/Tyvek®, packaged in a cardboard carton. The Barrigel needle is identical to the needle used during the Barrigel IDE study and is manufactured for Palette Life Sciences by R.K. Manufacturing.

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

The SpaceOAR Hydrogel System consists of components for the preparation of a synthetic, absorbable hydrogel spacer and a delivery mechanism provided in a sterile, single use package. The SpaceOAR hydrogel is a synthetic, absorbable polyethylene glycol (PEG)based hydrogel that upon injection creates a space that temporarily positions the anterior rectal wall away from the prostate during radiotherapy for prostate cancer, and in creating this space it is the intent of the perirectal spacer to reduce the radiation dose delivered to the anterior rectum. SpaceOAR hydrogel is completely synthetic with no animal or human derived components. It is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment (approximately 3 months) and is completely absorbed by the patient's body over time (approximately 6 months).

SpaceOAR Vue Hydrogel 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 SpaceOAR Vue Hydrogel to reduce the radiation dose delivered to the anterior rectum. The SpaceOAR Vue Hydrogel is composed of biodegradable material and maintain space for the entire course of prostate radiotherapy treatment and is completely absorbed by the patient's body over time.

The SpaceOAR Vue Hydrogel consists of components for the preparation of a synthetic, absorbable hydrogel spacer and a delivery mechanism provided in a sterile, single use package. The SpaceOAR Vue Hydrogel is a synthetic, absorbable polyethylene glycol (PEG)-based hydrogel that upon injection creates a space that temporarily positions the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of the perirectal spacer to reduce the radiation dose delivered to the anterior rectum. SpaceOAR Vue Hydrogel is completely synthetic with no animal or human derived components. It is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment (approximately 3 months) and is completely absorbed by the patient's body over time (about 6 months). The SpaceOAR Vue Hydrogel consists of two syringes containing the PEG Precursor solution and the Accelerator solution (a buffered salt solution). The Precursor solution is formed by the user through the reconstitution of PEG powder with a Diluent (Trilysine buffer) solution (that is provided in a third syringe). The Accelerator solution is provided ready for use. The Syringes filled with the Precursor solution and the Accelerator solution are assembled with other applicator components, including a Y-connector for mixing the Precursor and Accelerator, and a needle to facilitate delivery of the hydrogel by injection to the tissue located between the anterior rectal wall and the prostate.

SpaceOAR System is a polyethylene glycol (PEG) hydrogel that upon injection creates a space that temporarily positions the anterior rectal wall away from the prostate during radiotherapy for prostate cancer with the intent to reduce the radiation dose delivered to the anterior rectum. The SpaceOAR System consists of components for the preparation of a synthetic, absorbable hydrogel spacer and a delivery mechanism provided in a sterile, single use package. Once assembled as shown in the figure above, the Y-connector allows for hydrogel injection via an 18 gauge needle. The spacer is formed by mixing two solutions, the Precursor and the Accelerator. The Precursor solution is formed through the mixing of the Diluent solution (Trilysine buffer solution) with the PEG powder. The Accelerator solution is a salt buffer solution.
