Abstract
Systems, devices and methods for eluting an agent at a treatment site are disclosed. The devices include an expandable frame and at least one membrane. The membrane may carry an agent to elute at the treatment site. The membrane may allow blood flow at the treatment site during agent delivery.
Claims7
An agent delivery device comprising:
- a guide wire having a proximal end and a distal end;
- and
- an expandable device at the distal end of the guide wire, the expandable device having two or more expandable, elliptical wire loops comprising opposing ends and a central working length adapted to contact an arterial wall and a polymeric membrane having an elutable agent, the membrane attached to the two or more expandable, elliptical wire loops between the ends of the loops and having a length about equal to the central working length of the loops, the membrane adapted to protect the luminal surface of the vessel from elevated shear stress and to carry the elutable agent into the arterial wall while the polymeric membrane is in contact with the luminal surface of the artery.
