MEDICAL DEVICE FOR INTERNAL TREATMENT WITH HEAT AND ADMINISTRATION OF MEDICINES.

摘要

A medical device (1) for effecting heat treatment and local administration of a fluid medicament to a body tissue that has a predetermined section of a boundary wall of a passage of a human or animal body, comprising a member (12 ) as a catheter to introduce it in the passage to a predetermined insertion position, the catheter member being provided with an inflatable balloon structure (11) having a boundary wall that can be inflated against the body tissue when the member ( 12) as a catheter is in the predetermined insertion position and means of administration (2, 11, 25) for the local administration of the fluid medicine to the body tissue when the catheter member (12) is in the position of predetermined insertion, and a heating arrangement (10, 15) that is intended to heat the body tissue when the catheter-like member (12) is ra in the predetermined insertion position, characterized in that the administration means (2, 11, 25) comprise a delivery channel (25) for supplying the fluid medicine to the balloon structure (11) and a border wall construction ( 2) of the balloon structure (11) that is permeable to the fluid medication, whereby the supply of the fluid medication to the balloon structure through the delivery channel (25) when the catheter-like member (12) is located in the predetermined insertion position, it causes the balloon structure (11) to inflate and fluid medication to be administered locally to the body tissue through the boundary wall (2) of the balloon structure (11), and because the arrangement heating (10, 15) comprises a heating element (10) that is arranged to heat the fluid medicine before it is discharged from the member (12) as a catheter, whereby the body tissue can be heated by fluid cament (13) administered locally to it through the boundary wall (2) of the balloon structure (11), when the catheter-like member (12) is in the predetermined insertion position.
