Abstract

The present invention relates to a catheter (11) with an expandable distal end (31) for delivery one or more medicaments. The distal end is coated with a hydrogel copolymer encapsulating one or more medicaments. The construction of the device facilitates electrophoretic and electro-osmostic mobilities of the medicaments.
