Abstract:

Routine manual inflation of a PTCA balloon produces uncontrolled arterial trauma, prolonged pain and a high rate of restenosis. We developed CAPSID in order to reduce the traumatic dilatation. The program starts with a slow (over 20 sec) 3 atmosphere incremental pressure rise inflation, followed by rapid deflation (20 sec) and reperfusion (20 sec), and then intermittent cycles of successive incremental pressure inflations (each time by 1 atmosphere) until full dilation is achieved, or by a continuous single slow gradual inflation over 120sec. Results are compared with those received in patients undergoing standard angioplasty.

Status:
Ongoing study
