MECHANICAL APPARATUS AND METHOD FOR DILATING AND DELIVERING A THERAPEUTIC AGENT

摘要

A mechanical dilatation and medicament delivery device (11) for enlarging a flow passage by dilating and delivering a liposome or micelle-encapsulated therapeutic agent to an obstruction in the vessel. The invention comprises a substantially cylindrically shaped expansion member (31) and includes a means engaged to the expansion member for altering the distance between the proximal end and the distal end of the expansion member by transforming the expansion member between a diametrically contracted configuration to diametrically expanded configuration. A liposome or micelle-encapsulated therapeutic agent or medicament is coated on either the expansion member, or incorporated into a substrate coated on the expansion member.
