Embodiment Construction

[0017] In FIG. 1 an embodiment of the device according to the invention is shown, which comprises a catheter 12 . On a portion close to the first end of the catheter, a container 11 is provided; the walls of the container 11 are flexible and expandable. In a first embodiment, the container 11 is completely closed and contains a quantity of fluid 13 with corresponding heat transfer properties. Silicone oil and water are examples of such fluids. The balloon-shaped container 11 is made of elastic silicone or other material (eg latex) with corresponding elastic properties.

[0018] Catheter 12 in FIG. 1 is inserted through the urethra such that the tip of catheter 12 enters voiding bladder 21 . To hold catheter 12 in place during the procedure, a balloon 22 near the tip of catheter 12 is inflated through a channel provided in catheter 12 in the usual manner. In the treatment mode shown, container 11 is placed in prostate 23 . The purpose of the treatment is to heat the prostat...

Abstract

A device for heat treatment of body tissue, comprising a catheter (12), which is insertable in the body and is equipped with an expandable fluid receptacle (11). The fluid receptacle (11) contains heating means (10) for convective heating of fluid contained in the receptacle (11) and, thus, heating of the tissue in an area of treatment located in the environment surrounding the fluid receptacle (11). The heating device (10) is connected to an energy supply unit (14) located outside of the body.

Description

technical field [0001] The invention relates to a device for thermal treatment of body tissue. Background technique [0002] Certain conditions of disease resulting from abnormal growth of body tissue can be successfully controlled using heat treatment. Tissue is heated to such an extent that the tissue dies. Certain forms of cancer and benign prostatic hyperplasia (BPH) are examples of such conditions. During processing, some parts of the tissue are processed while other parts must or should be preserved. The disease conditions that are primarily considered are those that are undamaged in the tissues surrounding the various cavities of the body. In addition to the examples given above, the following disease states should be mentioned: cancer of the esophagus, trachea, ureter and bowel. [0003] Animals may also exhibit similar disease conditions, and animals may be treated in the same way. In particular, it can be used as a treatment for domestic animals and pets such ...
