LOW-PROFILE SINGLE-LUMEN PERFUSION BALLOON CATHETER

摘要

A low-profile single-lumen perfusion and fluid delivery balloon catheter for dilatation angioplasty procedures includes a small diameter single-lumen catheter shaft carrying a dilatation balloon adjacent to the distal end thereof. A perfusion conduit is also carried by the catheter shaft and traverses the dilatation balloon to provide perfusion blood flow past the balloon when the latter is inflated. The catheter may be used in mono-rail configuration to facilitate retracing of a subsequent catheter or other therapeutic device along the mono-rail guide wire back to the vascular site under treatment.
