Systems and methods for treating cancer using brachytherapy
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.
CATHETER APPARATUS AND BRACHYTHERAPY SYSTEM
A catheter apparatus (10) includes a tubular member (11); multiple fluid-flow pipe members (13), each having a proximal end (19) and a distal end (18), and being disposed along a first axial direction of the tubular member; multiple node members (15) disposed along a first axial direction of the tubular member, wherein two adjacent node members (15) form a segment (1a); and a periphery member (14), wherein the periphery member (14) wraps the multiple node members (15) to form a space (1b) with the segment (1a) formed between the two adjacent node members (15). The catheter apparatus (10) can irradiate the entire diffuse tumor during one brachytherapy process without repeated placement of the catheter. Meanwhile, it can be smoothly inserted into the patient's narrow body cavity because there are no external balloons. A brachytherapy system adopts the catheter apparatus (10).
MULTI-PURPOSE BALLOON CATHETER FOR INTRA CAVITY RADIATION DELIVERY
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.
Multi-purpose balloon catheter for intra cavity radiation delivery
A multi-purpose balloon catheter includes a catheter having a proximal end portion, a central portion and a 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 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 and deflated to position and stabilize the catheter in a cavity for delivery of a treatment. The catheter can include an extraction point associated with a lumen to remove fluids and material from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a liquid saline solution, a fluid medium, or a radioactive isotope provided to a corresponding lumen for delivery of the treatment.
BALLOON CATHETER SYSTEM AND METHOD FOR OPTICAL TUMOR TREATMENT
A balloon catheter system includes: a light irradiation probe including, at a distal end portion of a fiber probe, a light irradiation portion for irradiating light; a balloon catheter including a shaft having a through hole through which the light irradiation probe is insertable, the through hole allowing liquid feeding, with the light irradiation probe being arranged, and a balloon provided to the shaft and configured to be expandable and contractable by a liquid injected into the balloon; and an injection apparatus including a measuring portion capable of measuring a quantity of the liquid, and an injection portion for injecting the liquid measured by the measuring portion into the balloon, and the balloon expands by the injected liquid, to thereby extend a wall of a region to be treated and retain the wall of the region to be treated in an extended state.
BEAM HARDENING FOR INTRAOPERATIVE RADIATION THERAPY USING A BALLOON APPLICATOR
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.
