ENDOVASCULAR MULTI-BALLOON CATHETERS WITH OPTICAL DIFFUSER FOR TREATMENT OF VASCULAR STENOSES

摘要

An interventional vascular therapeutic device (100) including a catheter shaft (110) having a pair of occlusion balloons (132, 134), a dilatation balloon (136) disposed on the catheter shaft between the occlusion balloons, a first inflation lumen (112) and a second inflation lumen (113) cofigured to supply inflation fluid to a proximally disposed one and a distal on of the occlusion balloons, a third inflation lumen (115) configured to supply inflation fluid to the dilatation balloon, a primary lumen (111) extending the entire length of the catheter configured to slidably receive a guidewire, and an infusion lumen (114) extending from a proximal end of the catheter shaft toward the distal end of the catheter shaft and terminating at an infusion exit port (140) located between the occlusion balloons. The device including an optical fiber (480) configured to be inserted into the primary lumen in exchange for the guidewire.
