Abstract:
A medicament delivery system configured for selectively delivering a medicament to a target location in a body lumen of a patient comprising:a resilient hollow cylinder of permeable foam, said cylinder having an outer surface, a central lumen, and proximal and distal ends, the cylinder defining proximal and distal openings of the central lumen and a fluid pathway therethrough, enabling fluid flow through the body lumen past the cylinder via the central lumen; a delivery device configured for introducing the cylinder into the patient's body lumen, said delivery device having a proximal end and a distal end, and said cylinder being compressed and attached near the distal end of said delivery device to enable advancement of the cylinder into the patient's anatomy for placement adjacent the target location; a sheath disposed over the cylinder and configured to be pulled open from a distal end thereby allowing for expanding the cylinder within the body cavity, the apparatus being configured to selectively allow said compressed cylinder to expand to contact the walls of the body lumen when said cylinder has been placed adjacent to the target location; and a medicament absorbed by the hollow cylinder, whereby the medicament is placed in contact with a walls of the body lumen at said target location.
