Innovating Localized Radiation Therapy

Pancreatic cancer survivor discusses CivaSheet® Implant

CivaTech Oncology® designs innovative products that bring meaningful improvements to low dose rate brachytherapy. The CivaString® and CivaSheet® can substantially reduce procedure time, provide homogeneous dose distribution and minimize trauma. Customizable CivaTech products insure that radiation oncologists can deliver individualized, targeted therapy to treat cancer.


CivaSheet® is the only FDA cleared, unidirectional, planar brachytherapy source. It is flexible, bioabsorbable and features CivaTech’s proprietary polymer encapsulated source technology.


CivaString® is a unique linear, polymer-encapsulated, low-dose-rate (LDR) brachytherapy source used to treat localized, solid tumors.


CivaDerm™ is a temporary radiation therapy product designed for intraoperative or surface radiation to treat skin cancer and other lesions.

Polymer source technology… What are the advantages you should know?

  • Only homogenous sources – eliminates hot/cold spaces
  • No source migration in clinical studies
  • Eliminates potential of long term metal toxicities

The novel CivaString®, CivaSheet® and CivaDerm™ seamlessly integrate into current clinical workflows, beginning with your usual imaging modalities, through treatment planning, and ending with post-implant dosimetry.

“Dr. Prestidge indicated he got 99.9% coverage of the prostate using 12 needles. I perhaps was in recovery for less than an hour. I felt very very comfortable; I had virtually no discomfort for a good period of time.”
CivaString® Patient
“I got the CivaString and the results have been excellent! My first PSA after implant was .35 and my second PSA was .20. I am scheduled for my third blood test in July. Your product seems to have done the trick. I’m 75 and back playing racquetball”
CivaString® Patient

“Excellent quality implants across a range of gland sizes were accomplished. Prostate volume changes were minimal suggesting minimal swelling using the CivaString needles and strands. The product is robust with minimal movement (4%) evidenced by CT. Good dosimetry is achieved with both the pre-plans and post-plans. Using a line source, the number of needles required to deliver the radiation therapy is less than that reported with standard preloaded or stranded brachytherapy products. This study demonstrates that the CivaString product can be safely and effectively integrated into the LDR brachytherapy management of prostate cancers.”
