Voxel Rad, Ltd. — Clinical Innovation Series
A fully integrated applicator system — engineered for precision
The Voxel Rad brachytherapy applicator is a patented, single-unit intracavitary system designed for image-guided brachytherapy in cervical and uterine cancer treatment. It combines an articulating endoscopic tandem with two inflatable ovoids and dedicated organ-at-risk retractor balloons into one cohesive device.
Designed to address the clinical limitations of conventional applicators, the system enables accurate tandem placement under direct endoscopic visualization, consistent ovoid positioning, and active displacement of the bladder and rectum from the radiation field — all within a single procedure.
Four integrated components. One system.
Articulating Endoscopic Tandem
A flexible, articulating tandem designed for endoscopic placement under direct visualization. Conforms to uterine canal angle for accurate positioning and optimal dose delivery, reducing the risk of uterine perforation.
Inflatable Ovoids
Two inflatable ovoids assembled as part of the single-unit system. Adapt to patient anatomy for consistent and reproducible applicator placement, ensuring reliable dose coverage to the clinical target volume.
Bladder Retractor Balloon
An integrated retractor balloon that physically displaces the bladder away from the radiation field, significantly reducing bladder dose and the risk of radiation-related urinary complications.
Rectal Retractor Balloon
An integrated retractor balloon that physically displaces the rectum from the ionizing radiation field, reducing rectal dose and lowering the risk of late gastrointestinal toxicity in treated patients.

Patent Portfolio 2025
The complete list of Voxel Rad's 15+ granted US patents spanning Radiation Oncology Brachytherapy, Surgery, Angionavigation & Therapeutics, and Medical Imaging innovations.
Designed to overcome the limitations of conventional applicators
Articulating tandem conforms to uterine canal angle
The articulating mechanism accommodates varied uterine anatomy, enabling precise angulation and positioning without requiring multiple applicator sizes.
Built-in endoscopic camera enables image-guided placement
Direct endoscopic visualization during tandem placement reduces the risk of uterine perforation and improves placement accuracy compared to blind insertion techniques.
Inflatable ovoids adapt to patient anatomy
Conformable inflatable ovoids ensure consistent, reproducible positioning across varied patient anatomy, improving dose coverage to the clinical target volume.
Integrated retractors protect bladder and rectum
Dedicated bladder and rectal retractor balloons physically move organs at risk away from the high-dose region — a meaningful improvement over passive shielding alone.
Single-use, pre-assembled for fast and sterile deployment
The fully pre-assembled, single-use design eliminates reprocessing requirements, reduces setup time in the treatment suite, and ensures sterility for every procedure.
Patented innovation
Protected by granted US patents across the applicator system, component design, and organ-sparing mechanisms — representing over 15 years of focused development.
Protected by granted US patents
