Balloon embolectomy catheters in small arteries. III. Surgical significance of eccentric balloons.

Some embolectomy balloons distend eccentrically. This study was undertaken to compare balloon eccentricity in air with that which occurs in arteries, to determine the influence of balloon eccentricity on shear force, and to estimate the injury potential of eccentric balloons. We studied 21 Edwards and 17 Shiley catheters in 24 dog carotid arteries in vitro… (More)
