✦ Synopsis

Oscillating pressure inflations may minimize trauma to the coronary artery during coronary angioplasty. We measured in vitro diameters of polyolefin copolymer compliant angloplasty balloons (as a surrogate for pressure) during pressure oscillation at the inflator to determine if pressure oscillations at the inflator were conducted to the balloon. Balloon diameter oscillation increased as cycle length and inflator pressure amplitude increased. Currently practiced oscillating inflation (cycle length 2-3 sec, amplitude 2-3 atm) did not effectively transmit oscillation to the balloon. Clinically feasible optimal balloon oscillation was achieved at a cycle length of 6 sec and pressure amplitude of about 3 atm.

A relation between restenosis and arterial lesions resulting from balloon angioplasty has been suggested in literature. Nevertheless, it is unclear to what extent angioplastyinduced arterial wall lesions contribute to the occurrence of restenosis. One problem is that arterial ruptures cannot be dete
