Claim Text:
1. A system for treating cervical and/or uterine cancers in brachytherapy with an intracavitary brachytherapy applicator, comprising: a tandem adapted for insertion into a cervix of a patient, wherein the tandem comprises an endoscopic viewing element to facilitate treatment and one or more radiographic markers; an ovoid assembly comprising first and second adjustably inflatable capless colpostats and an ovoid support mechanism, the ovoid support mechanism adapted to support the colpostats and to allow for user manipulation to control the relative position of the colpostats for insertion of the colpostats within the fornices of a patient, the first and second adjustably inflatable capless colpostats having a deflated configuration for insertion into a patient and one or more adjustably inflated configurations for positioning the ovoid assembly during treatment, wherein a first handle portion of the ovoid support mechanism supports an inflation catheter shaft for delivering fluid through the first handle portion to control inflation of the first adjustably inflatable capless colpostat, and wherein a second handle portion of the ovoid support mechanism supports an inflation catheter shaft for delivering fluid through the second handle portion to control inflation of the second adjustably inflatable capiess colpostat, the ovoid assembly adapted to be pre-assembled as a single unit prior to insertion into a vagina of the patient such that the first and second adjustably inflatable capless colpostats in the deflated configuration are sized and configured to be simultaneously inserted into the patient as integrated pieces of the single unit during treatment, the first and second colpostats each having one or more radiographic markers, the ovoid assembly comprising a tandem connector adapted to releasably and adjustably couple the tandem to the ovoid assembly to allow for pivotal and translational motion of the tandem relative to the ovoid assembly and to limit rotational movement of the tandem about a longitudinal axis of the tandem; first and second adjustably inflatable retractors adapted to be releasably coupled to the ovoid assembly at first and second retractor connector portions, the first and second inflatable retractors having a deflated configuration for insertion into a patient and an adjustably inflated configuration for retraction of tissue during treatment, wherein the first retractor is adapted to be positioned to retract the bladder of a patient during treatment and the second retractor is adapted to be positioned to retract the rectum of a patient during treatment; wherein the tandem and the first and second adjustably inflatable capless colpostats are adapted to be coupled to a radioactive source to deliver an implant radiation dose suitable for cancer treatment at a cancerous cervical and/or uterine treatment site in a patient, wherein the first handle portion of the ovoid support mechanism supports a radiation transfer catheter shaft for delivering radiation through the first handle portion to the first adjustably inflatable capless colpostat, and wherein the second handle portion of the ovoid support mechanism supports a radiation transfer catheter shaft for delivering radiation through the second handle portion to the second adjustably inflatable capless colpostat.
