Complex coronary angioplasty: use of a new microprobe balloon catheter.
Since the introduction of coronary angioplasty by Gruntzig et al. (Circulation [Suppl II] 56:84, 1977), a key determinant to overall success has been advancement in equipment technology. Major advances have been made in the availability of low-profile catheters in the last 5 years that have facilitated penetration of high-grade distal and complex lesions. The USCl probe TM catheter is an example of a low-profile catheter that has shown favorable applicability in dilating high-grade stenoses. Preliminary data indicate that this device has good trackability and an extremely low profile, which allows penetration of stenoses where other current low-profile catheters have failed.
