Heatable implant device for tumor treatment

A method for treating a tumor or cancerous cells in a patient by thermotherapy, comprising the steps of:

• implanting an expandable implant device in a vessel with the implant device configured to circumferentially subtend the vessel upon expansion of the implant device in said vessel, the implant device comprising a set of cross-connected conductors forming a circumferential structure with openings in between the conductors, said openings having a minimal opening distance of at least 2 mm with the implant device in an expanded configuration, wherein the vessel and the implant position of the implant device in the vessel is pre-selected on the basis of distance to the tumor or cancerous cells and/or on the basis of nutrient supply flow to the tumor or cancerous cells;
• wherein the implant device comprises cavities at an outer surface of the implant device, the cavities being provided with one or more bioprobes and being closed off with a thermodegradable cover, wherein each bioprobe comprises a magnetic susceptor and at least one ligand;
• inserting an excitation catheter in the patient, wherein the excitation catheter comprises a longitudinal shaft with a distal end, a proximal end, and a longitudinal body in between, wherein the catheter comprises a longitudinal axis along the longitudinal shaft, and wherein the catheter further comprises an emitter coil at or near the distal end, and wherein the longitudinal body of the catheter further comprises a wiring lumen comprising electrical wiring extending from the distal end to the proximal end, and wherein the electrical wiring is connected at or near the distal end with the emitter coil,
• positioning the emitter coil of the catheter within the expanded implant device, and
• energizing the emitter coil to emit an alternating magnetic field, generating a current flow in the conductors of the implant device, heating the implant device with generated energy and re-radiating an alternating magnetic field to surrounding tissue;
• wherein the one or more bioprobes are released from the cavities and heated upon heating of the implant device by the generated energy.
