Abstract
Devices and methods are disclosed for treatment to tissue surrounding a body cavity or other intracorporeal site, such as after removal of tissue, e.g. cancer. Such a device includes a treatment location on a distal portion of the device with one or more radiation shielding components that partially encircle a radiation source at the treatment location to control emitted radiation from the radiation source. The device minimizes radiation damage to healthy tissue surrounding the body cavity or other site while irradiating tissue not shielded by the radiation shielding components. A device embodying features of the invention can include a sealing member at a location on a shaft of the device proximal to a treatment location to seal the passageway leading to the body cavity.
Claims28
A device for delivering a radiation source into a body cavity or other intracorporeal site within a patient, comprising:
- a.) an elongated shaft having a longitudinal axis, a distal portion with a treatment location and an arcuate shaped lumen which is off set from the longitudinal axis and which extends within the shaft to the treatment location;
- b.) an inner radiation delivery lumen configured to extend to the treatment location and which is configured to guide the radiation source to the treatment location;
- and
- c.) an arcuate shaped radiation shielding component which is slidably disposed within the arcuate shaped lumen and which partially encircles or is configured to partially encircle the treatment location of the distal portion of the elongated shaft.
A device for delivering a radiation source into a patient, comprising:
- an elongated shaft having a longitudinal axis, a distal portion with a treatment location, an arcuate shaped lumen which is radially spaced from the longitudinal axis and which extends within the shaft to the treatment location, and an inner radiation delivery lumen configured to extend to the treatment location;
- and
- an arcuate shaped radiation shielding component comprised at least in part of radiation absorbing material, and which is slidably disposed within the arcuate shaped lumen and which partially encircles or is configured to partially encircle the treatment location of the distal portion of the elongated shaft.
