Abstract
A brachytherapy device including a primary guide, a telescoping primary applicator, a locator assembly for fixing the primary guide and the telescoping applicator, and a control system for managing the different components of the device is described. The primary applicator can be adjusted based on patient anatomy. The locator assembly includes a secondary applicator and a secondary guide connected to an expandable structure that can be inflated after insertion into the patient.
Claims31
A brachytherapy device for administration of intrauterine radiation, the device comprising
- a primary guide configured to be inserted into a patient that extends along a primary guide axis and that defines a primary interior space along the primary guide axis,
- a telescoping primary applicator configured to temporarily house a first radioactive source within the patient that is customizable to the shape of patient-specific intrauterine anatomy, the telescoping primary applicator including
- (i) an extension configured to move from a retracted position arranged within the primary interior space of the primary guide to an extended position arranged largely outside the primary interior space of the primary guide, wherein the extension is configured to have a customized arcuate shape when in the extended position, and
- a locator assembly comprising
- (i) at least one secondary guide configured to be inserted into the patient that extends along a secondary guide axis and that defines a secondary interior space along the secondary guide axis, the secondary guide further including
- (i) an expandable structure surrounding the secondary radioactive source, the expandable structure configured to be in a position that ranges from a completely expanded position to a completely collapsed position, and
- (ii) a flexible skin configured to cover the expandable structure, and
- (ii) a secondary applicator positioned in each secondary guide configured to temporarily house a secondary radioactive source in the secondary interior space, and
- a control system including a first user input configured to drive motion of the extension in/out of the primary interior space and a second user input configured to control the position of the expandable structure.

A brachytherapy device for administration of intrauterine radiation, the device comprising
- at least one guide configured to be inserted into a patient that extends along a guide axis and that defines an interior space along the guide axis,
- an applicator positioned in each guide configured to temporarily house a radioactive source, the guide including
- i. an expandable structure surrounding the radioactive source configured to comprise an expanded diameter or a collapsed diameter, and
- ii. a flexible skin configured to cover the expandable structure, and
- a control system including a first user input configured to control the diameter of the expandable structure and a second user input configured to lock the diameter of the expandable structure, wherein the flexible skin is configured to prevent the radioactive source from contacting patient tissue.
