The polymer-encapsulated CivaString
The CivaString LDR sources are color coded based on the customized activity levels ordered
CivaString is a unique linear, polymer-encapsulated, low-dose-rate (LDR) brachytherapy source used to treat localized, solid tumors. The CivaString source features 103Pd along the full length of the device which is contained using low-Z polymers. The polymer construction and linear radioactive distribution of the CivaString creates a very homogenous dose distribution that has advantages for patients.
Most radioactive seeds are encapsulated in metal; CivaString is unique in its polymer encapsulation. CivaString fits into the current brachytherapy seed regimen for treating prostate and other localized cancers; however, the product’s properties are being advantageously used to generate new, customized treatment plans.
CivaString treatment plans offer several advantages for the radiation oncologist, medical physicist and patient. CivaString treatment pre-plans generally reduce the number of needles1.
