Abstract
Provided are multi-segmented inflatable brachytherapy devices. Also provided are systems and methods including multi-segmented inflatable brachytherapy devices.
Claims29
A sleeve for positioning on a brachytherapy applicator, comprising:
- (a) a first inflatable segment having a primary lumen;
- (b) a second inflatable segment having a primary lumen;
- and
- (c) wherein the first and second segments are selectively inflatable by delivery of fluid into each lumen.
1 more element
13-18. (canceled)
A system for providing brachytherapy treatment, comprising:
- (a) a brachytherapy applicator for insertion into a cavity of a subject;
- (b) a sleeve for positioning about the brachytherapy applicator, said sleeve comprising a first inflatable segment having a primary lumen and a second inflatable segment having a primary lumen, wherein the first and second segments are selectively inflatable by selective delivery of fluid into each primary lumen;
- and
- (c) a fluid delivery apparatus for delivering fluid into each primary lumen, wherein the fluid delivery apparatus delivers the fluid with sufficient force to cause inflation of each segment and movement of subject tissue when said applicator and sleeve are positioned within the cavity.
1 more element
A method of reducing radiation exposure of tissue in a subject, comprising:
- (a) inflating an inflatable device with a contrast agent wherein the inflating expands the size of the device and causes movement of the tissue;
- and
- (b) applying radiation to the subject, wherein exposure of the moved tissue is reduced.
