Abstract: A brachytherapy apparatus and a brachytherapy method using the brachytherapy apparatus are provided. The brachytherapy apparatus includes a rod-shaped main element, a first holder, a second holder, side elements which extend between the first holder and the second holder and which are flexible and connected to the first holder and the second holder in such a way that a change in the relative position of the first holder in relation to the second holder brings about a change in the distance between the main element and the at least one side element, and a measuring apparatus configured to specify a measurement value based on at least one coordinate of the relative position of the first holder in relation to the second holder, said measurement value representing a quantity that depends on the distance.

Abstract: The disclosure relates to a brachytherapy system. The brachytherapy system comprises a radiation generation apparatus for generating x-ray radiation, a controller for controlling the radiation generation apparatus, an applicator, which is embodied in such a way that it can be placed on the radiation generation apparatus, and an information transmission system, which is configured to capture an information item embodied in or at the applicator if the applicator has been placed on the radiation generation apparatus and to transmit the captured information item to the controller. The controller is configured to control the generation of x-ray radiation and the output of warnings on the basis of the received information item.

Abstract: A balloon applicator for irradiation of a cavity within living tissue is provided, comprising a double-lumen shaft and with a balloon connected to the shaft at a proximal and a distal position, in which a movement of a first portion of the shaft relative to a second portion of the shaft can be effected. In addition, a tool is provided which can be inserted into a lumen of the shaft and which is designed to effect the relative movement. Furthermore, a system is provided composed of balloon applicator and tool.

Abstract: A balloon applicator (1) for irradiation of a cavity within living tissue is provided, comprising a double-lumen shaft (2) and with a balloon (3) connected to the shaft (2) at a proximal (4) and a distal position (5), in which a movement of a first portion of the shaft (2a) relative to a second portion of the shaft (2b) can be effected. In addition, a tool (30) is provided which can be inserted into a lumen of the shaft (7) and which is designed to effect the relative movement. Furthermore, a system (40) is provided composed of balloon applicator (1) and tool (30).

Abstract: Balloon catheter, applicator, particularly for invasive radiotherapy, and method of controlling the balloon catheter with respect to its shape and position in a tissue to be treated prior to an irradiation. The balloon catheter provides a catheter shaft for introducing a probe, an outer balloon and an inner balloon, disposed inside the outer balloon, the inner space of the inner balloon connecting to a channel for connection to a media inlet and intermediate space between the outer balloon and the inner balloon connecting to a channel for connection to a media storage unit. In order that the balloon catheter can be securely controlled with respect to its shape and position in a patient in a simple but clear manner prior to irradiation, the outer balloon is formed of a flexible, non-extendible material and the inner balloon is formed of a flexible, extendible material.

Abstract: The present invention relates to a balloon catheter (10) as well as an applicator (50), particularly for invasive radiotherapy. The balloon catheter (10) provides a catheter shaft (11) for introducing a probe (40), a first, outer balloon (20) and a second, inner balloon (30), disposed inside the outer balloon (20), the inner space (31) of the second, inner balloon (30) connecting to a channel (32) for connection to a media inlet (41) and intermediate space (21) between the first, outer balloon (20) and the second, inner balloon (30) connecting to a channel (22) for connection to a media storage unit (42). In order that the balloon catheter can be securely controlled with respect to its shape and position in a patient in a simple but clear manner prior to irradiation, it is provided according to the invention that outer balloon (20) is formed of a flexible, non-extendible material and that inner balloon (30) is formed of a flexible, extendible material.

Abstract: An applicator means (20) for radiation therapy, having at least one first applicator element for taking up a probe tip or a radiation source element (12) of a radiation source means (11), as well as a radiation therapy device (10) are described. In order to avoid an undesired slipping out of position of applicator means (20), particularly during the irradiation process, it is provided that the first applicator element is designed as an inner applicator element (21), which has a foot region (22), by means of which inner applicator element (21) can be attached to radiation source means (11), that applicator means (20) has a second applicator element which is designed as an outer applicator element (24) relative to inner applicator element (21), that outer applicator element (24) has an uptake space (28) for taking up at least one component of inner applicator element (21), and that inner applicator element (21) is designed so that it can be introduced into outer applicator element (24), at least in regions.

Abstract: The invention relates to a balloon catheter for an X-ray applicator and an X-ray applicator—for use with the corresponding balloon catheter. Said balloon catheter can be filled with a medium and comprises a balloon—that expands with respect to the volume and a catheter shaft for inserting the X-ray applicator. Said balloon or the catheter shaft comprises a rigid inner end piece in the extension of the catheter shaft.
