The GliaSite balloon catheter

The GliaSite catheter is a radiopaque silicone tube with a low-profile infusion port at the proximal end and a silicone balloon at the distal end.

The distal balloon is actually a dual-balloon configuration. The inner balloon serves as a reservoir for Iotrex^® Radiotherapy Solution, the liquid radiation source, while the outer balloon is a safety reservoir in the event that the inner balloon is compromised.

The infusion port has a self-sealing septum and is connected to the primary lumen in the catheter for accessing the inner balloon. A secondary lumen in the catheter provides access to the outer balloon if necessary.
