Abstract
Medical device ( ) for effecting heat treatment and local delivery of a fluid medicament on body tissue presenting a predetermined section of a boundary wall of a passageway in a human or animal body comprising a catheter-like member ( ) for insertion into the passageway to a predetermined insertion position, the catheter-like member being provided with an inflatable balloon structure ( ) having a boundary wall which is inflatable against the body tissue when the catheter-like member ( ) is in the predetermined insertion position and delivery means ( ) for local delivery of the fluid medicament on the body tissue when the catheter-like member ( ) is in the predetermined insertion position, and a heating arrangement ( ) which is adapted to heat the body tissue when the catheter-like member ( ) is in the predetermined insertion position. The delivery means ( ) comprises a supply channel ( ) for supply of the fluid medicament to the balloon structure ( ) and a construction for the boundary wall ( ) of the balloon structure ( ) which is permeable to the fluid medicament. Supply of the fluid medicament to the balloon structure along the supply channel ( ) when the catheter-like member ( ) is in the predetermined insertion position thereby causes the balloon structure ( ) to inflate and fluid medicament to be delivered locally on the body tissue through the boundary wall ( ) of the balloon structure ( ).
