Systems and methods are provided for treating cervical and/or uterine cancers in brachytherapy with an intracavitary brachytherapy applicator. The system comprises a tandem adapted for insertion into a cervix of a patient. An ovoid assembly comprises first and second inflatable ovoids and an ovoid support mechanism. The first and second inflatable ovoids are adapted for insertion within fornices of a patient. First and second retractors are adapted to be coupled to the ovoid assembly. The first retractor is adapted to be positioned to retract the bladder of a patient during treatment. The second retractor is adapted to be positioned to retract the rectum of a patient during treatment. The tandem and the first and second inflatable ovoids are adapted to be coupled to a radioactive source to deliver an implant radiation dose suitable for cancer treatment at a cancerous cervical treatment site in a patient.

The invention describes method for delivering and positioning radio-isotopes. The method uses encapsulating free flowing medicament into a leak proof vehicle and positioning the vehicle into the body. Also provided is a system for delivering and positioning radio-isotopes into the body, the system comprising fluid radio-isotope encapsulated in a leak proof material and/or absorbable material.

An apparatus for providing treatment to at least one tissue includes a distal balloon, a proximal balloon, and an intermediate balloon positioned between the distal balloon and the proximal balloon and inflatable independently from the distal and proximal balloons. A source lumen is positioned within at least the intermediate balloon receives a radiation source to treat target tissue adjacent the intermediate balloon.

A dual double balloon catheter includes a catheter having a proximal end portion, a central portion and a distal end portion, and a secondary treatment balloon for a catheter. The catheter includes a plurality of lumens within the catheter extending from the proximal end portion, a plurality of inflatable balloons positioned in the central portion and a secondary treatment balloon communicatively associated with the distal end portion of the catheter, and the balloons and the secondary treatment balloon being communicatively connected with a corresponding one of the plurality of lumens to selectively inflate/deflate the corresponding inflatable balloon or to receive a radioactive dose or a therapeutic agent for a treatment.

The invention provides a device for treating tumors at a target site, the device comprising a first balloon containing a radio isotope; a second balloon encasing the first balloon wherein the second balloon comprises structures to create a void between the first balloon and the second balloon; and a third balloon encasing the second balloon, wherein the third balloon facilitates removal of material from the target site. The invention also provides a method for treating a tumor excise site, the method comprising simultaneously exposing the tumor to heat and radiation.

A multi-purpose balloon intra-cavity catheter includes a catheter having a proximal end portion, a central portion and a non-branching distal end portion, a plurality of lumens associated with the catheter extending from the proximal end portion, and a plurality of inflatable balloons positioned in the central portion and/or the non-branching distal end portion. Each of the plurality of inflatable balloons is communicatively associated with a corresponding one of the plurality of lumens, the plurality of inflatable balloons being selectively inflated or deflated to position and stabilize the catheter in a cavity for delivery of a medical treatment. The catheter can include an extraction opening associated with a lumen to remove fluids and materials from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a fluid medium or a radioactive isotope provided to a corresponding lumen for delivery of the medical treatment.

Systems and methods are provided for treating cervical and/or uterine cancers in brachytherapy with an intracavitary brachytherapy applicator. The system comprises a tandem adapted for insertion into a cervix of a patient. An ovoid assembly comprises first and second inflatable ovoids and an ovoid support mechanism. The first and second inflatable ovoids are adapted for insertion within fornices of a patient. First and second retractors are adapted to be coupled to the ovoid assembly. The first retractor is adapted to be positioned to retract the bladder of a patient during treatment. The second retractor is adapted to be positioned to retract the rectum of a patient during treatment. The tandem and the first and second inflatable ovoids are adapted to be coupled to a radioactive source to deliver an implant radiation dose suitable for cancer treatment at a cancerous cervical treatment site in a patient.

A balloon applicator for an intraoperative radiation therapy system includes an x-ray beam shaping component for emitting x-rays in a plurality of possible directions in three dimensions. The balloon applicator includes connecting structure for connecting to the intraoperative radiation therapy system and an inflatable balloon contactor having an outer surface. The balloon applicator has a beam hardening system including a beam hardening compound disposed between the x-ray beam shaping component and the outer surface of the balloon. The beam hardening system is capable of hardening the beam in beam directions in three dimensions. An intraoperative radiation therapy system and a method for conducting intraoperative radiation therapy are also disclosed.

Validation of a therapeutic radiation treatment involves using an applicator balloon surrounding an X-ray radiation source to support a plurality of X-ray sensor elements (XRSE). The XRSE are supported on the applicator balloon at distributed locations to sense applied radiation from the radiation source. At least one parameter of the applied radiation which has been sensed by the XRSE is compared to a corresponding parameter of a predetermined radiation treatment plan. Based on the comparing, a determination is made as to whether one or more requirements of the predetermined radiation treatment plan have been satisfied.

Embodiments of the present disclosure relate to a modular applicator for enabling a brachytherapy treatment, comprising a central core and an outer sleeve, wherein the central core is adapted with a fixation mechanism for affixing the outer sleeve to the central core, wherein the outer sleeve is manufactured from a substantially rigid or shapeable material.
