Contura multi-lumen balloon is a single insertion balloon brachytherapy applicator available in two sizes and two shaft configurations (standard and FLEX). With five treatment lumens, you can shift the isodose curve from the chest wall. There are two vacuum ports on the proximal and distal ends of the balloon that allow you to remove fluid or air to facilitate tissue conformance to the balloon.
Both MammoSite and Contura multi-lumen balloon brachytherapy applicators are the only single-insertion APBI technologies that meet or exceed all B-39 dosimetric guidelines.
As such, they allow you to easily satisfy the current clinical recommendation that the dose to the skin be maintained to less than 125% of the prescription dose.3-5
