Embodiment Construction

[0060]1 is a schematic diagram of a device for interactive interstitial photodynamic phototherapy (PDT) or radiant thermal therapy (PTT) and photodynamic diagnosis (PDD) on human or animal body surface or internal body parts. Multiple or at least two radiation conductors, such as optical waveguides or optical fibers 6 are inserted directly into tissue 8, which may be an organ, a tumor or any other tissue. The fibers 6 can be inserted with their distal ends interstitially into the tissue 8, respectively, in a geometric pattern. Therefore, fiber 6 is a patient fiber. As shown in Figure 1, the distal ends of the patient's fibers 6 are arranged in a geometric pattern overlying an area to be studied and / or treated. As shown in FIG. 1 , the proximal end of the patient's fiber 6 arranged away from the tissue is inserted and attached to the flat disc 3 of the conversion means 1 . The flat disk 3 and the second flat disk 4 are arranged adjacent to each other, and the flat disks can r...

Abstract

A system configured for photodynamic or photothermal therapy and photodynamic diagnosis of a tissue is disclosed. The system comprises in combination an assembly of: a proximal end adapter for a catheter comprising an adapter body (32), having proximal and distal ends, defining an axial lumen extending between the proximal and distal ends, a catheter mounting element at the distal end 10 of the adapter body (32) for sealingly mounting a catheter to the adapter body, and a hollow catheter (31), wherein the catheter mounting element connects a catheter body to the hollow catheter so that the hollow catheter extends from the distal end of the catheter body; a first light 15 guide (36) having proximal and distal ends, wherein said first light guide is sealingly contained in said axial lumen defining an axial optical path extending between the proximal and distal ends of the adapter body (32) towards said tissue (8) and into close proximity thereof or 20 interstitially into said tissue; an optical connector mounting element at the proximal end having mounted an optical connector (37) to the adapter body, and wherein said optical connector (37) is coupled to a light source via a second light guide (38), such that light from said 25 light source is transmittable from said light source via said second light guide (38) and further via said optical connector (37) to said first light guide (36) via said proximal end adapter towards said tissue (8) through said catheter (31).

Description

technical field [0001] The invention relates to a system for interactive interstitial photodynamic or radiant thermal therapy and / or tissue diagnosis, realized by means of a device having at least one therapeutic or diagnostic light source, and at least one radiation conductor, and an optical coupler adaptation mechanism , the at least one therapeutic or diagnostic light source is for example a laser radiation source, the at least one radiation conductor is for example an optical waveguide in the form of an optical fiber for transmitting light between the tissue and the device, for example from the laser radiation to the Said tissue, said optical coupler adaptation mechanism for conveniently connecting an optical path comprising said optical fiber between the tissue and the device, eg to said laser source. Background technique [0002] Systems and methods for photodynamic tumor therapy (PDT) and / or radiative thermal tumor therapy (PTT) and photodynamic diagnostics (PDD) usin...
