Apparatus and method for inhibiting restenosis by applying ultrasound energy together with drugs

摘要

A system and method for inhibiting restenosis by compromising the migration, viability and adhesion of mammalian smooth muscle cells (SMC). The system includes an ultrasonic energy source; a transmitter for transmitting the ultrasonic energy to the SMC and a drug delivery spectrum for delivering drugs to the smooth mucles cells. This system and method is especially useful in the prevention of restenosis in a blood vessel of a mammal associated with the migration of SMC in the blood vessel following vascular intervention, such as angioplasty.
