Abstract
A balloon catheter includes a sheath surrounding the balloon, the sheath having a longitudinal line of weakness and a drug-containing viscous matrix material intermediate between the balloon and the sheath such that when the balloon is positioned and inflated in the body lumen it causes the sheath to burst at the line of weakness and release viscous matrix material onto said body lumen. The device provides accurate placement of the dosage required at the location in need of treatment. The catheter is especially useful in balloon angioplasty procedures.
