Abstract
Systems and methods for minimally invasively delivering radiation therapy to a patient, e.g., with bladder cancer, is provided. The radiotherapy system includes one or more catheters that may be introduced to a patient's anatomical structure via a sheath using an intracavitary approach. The proximal end of the one or more catheters may be coupled to an afterloader for selectively delivering the radiation therapy, and the distal portion of the one or more catheters is transitionable between an uncoiled delivery state within the sheath and a coiled deployed state having a spherical configuration within the anatomical structure of the patient, such that the one or more catheters contacts at least a portion of the anatomical structure in the deployed state.
Claims20
A radiation therapy system to treat a patient, the system comprising:
- a sheath having a proximal end, a distal end, and one or more lumens extending therebetween;
- one or more catheters independently moveable within the one or more lumens of the sheath, a distal portion of the one or more catheters configured to transition from an uncoiled delivery state to a coiled deployed state having a spherical shape within an anatomical structure of the patient, the one or more catheters configured to selectively deliver radiation therapy to a target area within the anatomical structure in the coiled deployed state.
A method of delivering radiation therapy system to treat a patient, the method comprising:
- positioning a distal end of a sheath within an anatomical structure of a patient;
- inserting one or more catheters in an uncoiled delivery state within one or more lumens of the sheath until a distal portion of the one or more catheters is positioned adjacent the distal end of the sheath within the anatomical structure of the patient;
- moving the sheath relative to the one or more catheters until the distal portion of the one or more catheters is exposed beyond the distal end of the sheath and transitions to a coiled deployed state having a spherical shape within the anatomical structure of the patient;
- and
- selectively delivering radiation therapy via the distal portion of the one or more catheters to a target area within the anatomical structure in the coiled deployed state.
