Abstract
In accordance with the present invention, a method is provided for improving angioplasty procedures by reducing tissue damage during the procedure comprising infusing a non-emulsion, homogeneous solution of certain ethylene oxide-propylene oxide surface-active copolymers before, during and/or after the angioplasty procedure. The surface-active copolymer can be an ethylene oxide-propylene oxide condensation product with the following general formula: EQU HO(C.sub.2 H.sub.4 O).sub.b (C.sub.3 H.sub.6 O).sub.a (C.sub.2 H.sub.4 O).sub.b H wherein a is an integer such that the hydrophobe represented by (C.sub.3 H.sub.6 O) has a molecular weight of approximately 950 to 4000 daltons, preferably approximately 1200 to 3500 daltons, and b is an integer such that the hydrophile portion represented by (C.sub.2 H.sub.4 O) constitutes approximately 50% to 90% by weight of the compound.
