Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The researchers recognized the possible clinical usefulness of a shielded device or jig to help increase the accuracy but decrease the time of loading the seeds into the biocompatible material used intra-operatively. Therefore, the researchers created a prototype of a device called the GammaTile (GT) loader (design patent pending). The reusable device will be made of surgical quality stainless steel of sufficient thickness (greater than 10 half-value layers (HVL) to provide significant staff and user shielding as well as allowing it to be sterilized. It is utilized intraoperatively but off of the operative field and has no direct patient contact. Currently two sizes are planned. The first will accommodate a 2 inch x 2 inch collagen square and the second will accommodate a 1 inch x 1 inch collagen square. These are the most commonly used sizes of lyophilized collagen used in the Barrow Neurosurgical Institute (BNI) operating rooms (OR).
