System, method and kit for immobilization of a human's body part

A system for immobilization of a patient body part for radiotherapy applications comprising:

• a device comprising at least one flanged support member and at least one support member fixation means for mounting the at least one flanged support member to a fixation surface at a distance from said fixation surface, wherein the at least one flanged support member is adapted to receive and retain a first and a second frame;
• a first frame, comprising a first sheet for covering anatomical contours of a first area of said body part, wherein the first frame forms a circumferential rim for the first sheet;
• optionally a second frame, comprising a second sheet for covering anatomical contours of a second area of said body part which is not covered by the first sheet, wherein the second frame forms a circumferential rim for the second sheet, wherein the second frame is superimposable on the first frame, wherein the first sheet and the second sheet form a double shell mask enclosing said body part;
• characterized in that the at least one flanged support member comprises at one side a curved extension towards the fixation surface, wherein the first frame or the first frame and the second frame are bent to follow the curved extension of the at least one flanged support member.

A method for immobilization of a patient body part for radiotherapy applications comprising the steps of:

• mounting a device comprising at least one flanged support member and at least one support member fixation means to a fixation surface, wherein the at least one flanged support member is mounted with the at least one support member fixation means to the fixation surface at a distance from said fixation surface, wherein the at least one flanged support member is adapted to receive and retain a first and optionally a second frame;
• mounting a first frame, comprising a first sheet, to the at least one flanged support member;
• placing the patient body part to be immobilized on the first sheet thereby covering the anatomical contours of a first area of said body part;
• optionally mounting a second frame, comprising a second sheet, on the first frame to the at least one flanged support member thereby covering the anatomical contours of a second area of said body part which is not covered by the first sheet, to form a double shell mask enclosing said body part;
• characterized in that, the at least one flanged support member comprises at one side a curved extension towards the fixation surface, wherein the first frame or the first frame and the second frame are bent to follow the curved extension of the at least one flanged support member.

A kit for immobilization of a patient body part for radiotherapy applications, comprising:

• a device, comprising at least one flanged support member and at least one support member fixation means for mounting the at least one flanged support member to a fixation surface at a distance from said fixation surface;
• a first frame, comprising a first sheet, wherein the first frame forms a circumferential rim for the first sheet;
• optionally a second frame, comprising a second sheet, wherein the second frame forms a circumferential rim for the second sheet, wherein the second frame is superimposable on the first frame;
• characterized in that the at least one flanged support member comprises at one side a curved extension towards the fixation surface, wherein the first frame or the first frame and the second frame are flat and comprise at least at one side a deformable part, wherein the deformable part is deformable in a direction transverse to the fixation surface.
