Document Type and Number:
Japanese Patent JP3317724
Kind Code:
B2
Abstract:
A drug delivery catheter with an inflatable blood flow lumen includes a flexible tubular shaft (30) and an inflatable balloon assembly (10,12,14,16) disposed at the distal end of the shaft. The catheter is inserted into a vessel with the balloon assembly in an un-inflated form and the balloon member is positioned at the treatment site and inflated. The balloon member in an inflated form defines a region or pocket (26) between the balloon assembly and the vessel wall which contains the drug separate from blood flow. Apertures (40) are provided within the balloon assembly to provide the drug to the containment pocket. Blood is allowed to flow through the center (24) of the inflated balloon assembly.
