Abstract
The present invention relates to a catheter with an expandable distal end for delivering one or more medicaments. The catheter is manufactured with materials of construction that allow the transfer of electrical energy from the proximal end of the catheter to the distal expandable end. The catheter also has a means for controlling or manipulating the expandable distal end to expand and contract into various configurations. The distal end of the catheter is processed by a specific method of manufacturing whereby the expandable distal end is coated with one or more layers of a hydrogel copolymer wherein at least one layer of which coating encapsulates one or more medicaments and zero or more charged carriers to facilitate the electrophoretic and electro-osmostic mobilities of the medicaments.
