medical device for internal heat treatment and medikamentenverabreichung

摘要

Medical device (1) 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 (12) for insertion into the passageway to a predetermined insertion position, the catheter-like member being provided with an inflatable balloon structure (11) having a boundary wall which is inflatable against the body tissue when the catheter-like member (12) is in the predetermined insertion position and delivery means (2,11,25) for local delivery of the fluid medicament on the body tissue when the catheter-like member (12) is in the predetermined insertion position, and a heating arrangement (10,15) which is adapted to heat the body tissue when the catheter-like member (12) is in the predetermined insertion position. The delivery means (2,11,25) comprises a supply channel (25) for supply of the fluid medicament to the balloon structure (11) and a construction for the boundary wall (2) of the balloon structure (11) which is permeable to the fluid medicament. Supply of the fluid medicament to the balloon structure along the supply channel (25) when the catheter-like member (12) is in the predetermined insertion position thereby causes the balloon structure (11) to inflate and fluid medicament to be delivered locally on the body tissue through the boundary wall (2) of the balloon structure (11).
