The AR™ is a first of its kind, disposable brachytherapy applicator designed specifically for the treatment of anal and rectal cancers. The AR™ combines unique innovations with proven brachytherapy technology to bring a new solution to the question of anorectal cancer treatment.

Unique Device Dimensions

  • 2.3 cm uninflated insertion diameter for ease of placement
  • 8-10 cm effective treatment zone allows treatment of entire rectum without repositioning

Dual Balloon construction

  • 3.5-4 cm inner balloon inflated diameter creates consistent, repeatable source catheter positioning
  • Outer balloon creates protective spacing between source catheters and tissue, fully distending the rectum ensuring repeatable tumor coverage

VISIBLE

  • Radio-opaque contrast markers visible under X-ray, CT and MRI ensure consistent device placement.

REPEATABLE

  • Contrast Markers and handle markings ensure depth and rotational consistency
  • Inner balloon design ensures precise, consistent source catheter positioning
  • Consistent fill volumes ensure repeatable tissue spacing.

OPTIMAL

  • Compliant outer balloon ensures optimal tissue separation and conformity around tumors
  • Non-compliant inner balloon supports 8 evenly spaced treatment catheters ensuring optimal positioning for surface dose control
  • Device construction and materials designed to take full advantage of MRI guided brachytherapy

The E-APP™ is a first of its kind, disposable brachytherapy applicator designed specifically for the treatment of upper GI cancers. Five independently operable balloons are designed to maintain the central position of the source catheter in both straight and curved anatomy allowing for closer proximity of the target to the source while maintaining distance for healthy tissue.

Unique Device Properties

  • Central source catheter surrounded by 5 equally spaced, 2 cm (inflated) balloons create, ABS consensus recommended, mid-dwell distance of 1cm to target
  • 12 optimally spaced X-Ray, CT, and MRI compatible markers
  • 0.5 cm catheter diameter for ease of placement
  • Greater than 10 cm effective treatment zone allows treatment of entire tumor

Visible

  • Radio-opaque contrast markers visible under X-ray, CT and MRI ensure consistent device placement

Repeatable

  • Multi-balloon configuration is designed to ensure precise, consistent source catheter positioning
  • Twelve radio-opaque markers and exterior catheter markings ensure consistent placement relative to target
  • Consistent fill volumes ensure desired tissue spacing

Optimal

  • Compliant balloons designed to ensure optimal catheter location and conformity
  • Device construction and materials designed to take full advantage of MRI guided brachytherapy
  • Central catheter surrounded by balloons ensures accurate dose distribution to intended target
