Diastolic coronary stent deployment system for precise bifurcation lesion stenting

摘要

A system precise stent deployment in synchronization with the cardiac cycle includes a cable set having a first connector for connection to a source of a signal that is indicative of the status of the cardiac cycle, and a second connector for connection to a processor. The processor converts cardiac cycle data into a control signal for controlling inflation of a balloon catheter such that the balloon catheter reaches inflation at a point within the range of from about 55% to about 85% into the R-R interval. An inflation pump is provided for inflating the balloon responsive to the control signal. A third connector is in communication with the inflation pump, for releasable connection to the balloon catheter.
