Abstract
A new percutaneous transluminal coronary angioplasty catheter with multiple functions of balloon inflation, local drug delivery and coronary perfusion has been devised. The device consists of an inflatable lumen, a drug delivery lumen, and a perfusion (or guide wire) lumen. A drug can be infused from the port located distal to the inflated balloon during continuous blood perfusion via the perfusion lumen. Fluorescence-labeled heparin and peroxidase administered using the device permeated into denuded vessel tissues during ongoing perfusion and remained there for over 24 hr. This prototype device indicates the potential therapeutic implications of the concepts of the device.
