The balloon may be inflatable with the introduction of fluid into the balloon from the flexible catheter. The balloon may be composed of a plurality of sections, including a center section and side sections. The inflated balloon may have shapes such as cylindrical, semi-cylindrical, or pillow shape. The intracavity balloon catheter may further include a securing device, such as a positioning ring, for securing the position of an inserted intracavity balloon catheter. This securing device may be composed of two, matable components with a passage extending through. The flexible catheter may be insertable into the passage. Tabs may be provided, either on one of the components or on a locking mechanism provided between the components, to prevent sliding of an inserted flexible catheter. ## Claims ### Claim 1 An intracavity balloon catheter, comprising: a flexible catheter having a proximal catheter portion, a distal catheter portion having a distal tip, and a fluid passageway traversing between the distal tip and the proximal catheter portion; a balloon disposed at the distal end of the catheter, the distal tip of the flexible catheter extending into the balloon, the balloon inflatable between a deflated condition and an inflated condition by introduction of a fluid into the balloon from the distal tip of the flexible catheter; and, a positioning ring comprising a first component matable with a second component at a connection point, and a passage along a longitudinal axis of the positioning ring, the passage having a first opening at a first end of the first component and a second opening at a second end of the second component, wherein the flexible catheter is positionable through the passage, and wherein the positioning ring is securable to the flexible catheter between the proximal catheter portion and the distal catheter portion. ### Claim 2 (depends on 1) The intracavity balloon catheter of claim 1, further comprising: a plurality of tabs provided proximate to the first end and extending into the passage thereby preventing sliding of an inserted flexible catheter. ### Claim 3 (depends on 2) The intracavity balloon catheter of claim 2, wherein the plurality of tabs are resilient and angled towards the passage and the second component. ### Claim 4 (depends on 1) The intracavity balloon catheter of claim 1, further comprising: a plurality of ribs provided proximate to the second end, each rib running parallel to the longitudinal axis of the positioning ring. ### Claim 5 (depends on 1) The intracavity balloon catheter of claim 1, further comprising: a latching mechanism at the connection point, the latching mechanism comprising a first latch on the first component securable with a second latch on the second component. ### Claim 6 (depends on 1) The intracavity balloon catheter of claim 1, further comprising: a locking mechanism provided about the passage between the first end and the second end, the locking mechanism including a plurality of tabs projecting towards the passage. ### Claim 7 (depends on 1) The intracavity balloon catheter of claim 1, wherein the distal tip of the flexible catheter defines an opening adapted for the injection of the fluid into the balloon from the fluid passageway. ### Claim 8 (depends on 1) The intracavity balloon catheter of claim 1, wherein the fluid passageway is adapted to be controlled by a valve, and wherein the inflated condition of the balloon comprises between 40 cubic centimeters and 70 cubic centimeters of the fluid.
