Abstract
The disclosure describes devices and methods for asymmetrical irradiation at a body cavity or site, such as after removal of tissue, e.g. biopsy or cancer. One device includes a lumen which is off-set or off-settable from a longitudinal axis to increase the intensity of radiation received from a radiation source by a first tissue portion surrounding the body cavity and to reduce or minimize radiation received by a second tissue portion (e.g. healthy tissue) surrounding the body cavity.
Claims6
A method for treating tissue surrounding a body cavity of a patient, comprising:
- a) providing a device having a distal portion, a treatment location at the distal portion and at least one tubular member extending within the treatment location having a lumen extending therein having or configured to receive a radiation source;
- b) inserting the device into the patient and advancing the device therein until the treatment location is deployed within the body cavity;
- c) positioning at least one tubular member within the body cavity so that the lumen therein is closer to a first portion of tissue surrounding the body cavity than a second portion of tissue surrounding the body cavity;
- and
- d) providing a radiation source within the lumen of at least one tubular member closer to the first portion of tissue surrounding the body cavity to asymmetrically irradiate tissue surrounding the body cavity so that the first portion of tissue surrounding the body cavity receives a greater amount of radiation than the second portion of tissue surrounding the body cavity.
