SpaceOAR Vue™ System Perirectal Spacer for Prostate Radiation Therapy

SpaceOAR Vue 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 SpaceOAR Vue System to reduce the radiation dose delivered to the anterior rectum.¹

You see it when you CT it.

SpaceOAR Vue Hydrogel is the only FDA-cleared radiopaque PEG-based perirectal hydrogel spacer designed for CT visibility to help optimize radiotherapy treatment planning for prostate cancer.1

How it works

SpaceOAR Vue Hydrogel, the next-generation hydrogel perirectal spacer is designed to offer enhanced visibility on CT. Due to the close proximity between the rectum and the prostate, radiation therapy can unintentionally cause rectal toxicity. SpaceOAR Vue Hydrogel is designed to help reduce the radiation delivered to the rectum during treatment.1

Why choose SpaceOAR Vue Hydrogel

The radiopacity is designed to improve the contouring accuracy during treatment plan creation, when compared to SpaceOAR Hydrogel.1

Reducing the need for a post-implant MRI may reduce the overall treatment costs per patient and the hospital staff’s time spent in obtaining reimbursement authorization1

The visibility of SpaceOAR Vue Hydrogel on a CT scan is designed to help reduce under- or over-contouring of the prostate and rectum for improved accuracy (when compared to SpaceOAR Hydrogel) and potentially more precise treatment planning1

Integrating SpaceOAR Vue Hydrogel into your practice

Boston Scientific supports a thorough in-service training program for office staff, clinical staff, and physicians in the practice. A Boston Scientific representative brings the training to you, and it can be completed in approximately 1 hour for each group.

Clinical data

SpaceOAR Vue Hydrogel: The Next-Generation Radiopaque Hydrogel Spacer

Clinical summary: “Summarized findings of adding the potential for CT visibility to SpaceOAR Vue Hydrogel is anticipated to expand hydrogel accessibility for patients who cannot undergo MRI, eliminate dependence on MRI for hydrogel contouring, assist in daily IGRT, and further improve the convenience of hydrogel placement.”

  1. Data on file with Boston Scientific.

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.

SpaceOAR Vue Hydrogel contains polyethylene glycol (PEG) and iodine.

Prior to using these devices, please review the Instructions for Use for a complete listing of indications, contraindications, warnings, precautions, and potential adverse events.

As with any medical treatment, there are some risks involved with the use of SpaceOAR Vue Hydrogel. Potential complications associated with SpaceOAR Vue Hydrogel include, but are not limited to: pain associated with SpaceOAR Vue Hydrogel injection, pain or discomfort associated with SpaceOAR Vue Hydrogel, local inflammatory reactions, infection (including abscess), urinary retention, urgency, constipation (acute, chronic, or secondary to outlet perforation), rectal tenesmus/muscle spasm, mucosal damage, ulcers, fistula, perforation (including prostate, bladder, urethra, rectum), necrosis, allergic reaction (localized or more severe reaction, such as anaphylaxis), embolism (venous or arterial embolism is possible and may present outside of the pelvis, potentially impacting vital organs or extremities), syncope, and bleeding. The occurrence of one or more of these complications may require treatment or surgical intervention. URO-989810-AB
