Patent ID: 7955246

Claim:
A method of temporarily filling an intracorporeal site within a patient's body, comprising: a. providing a catheter device having an elongated shaft with a flexible proximal shaft section, a distal shaft section and a cavity filling member on the distal shaft section; b. forming a passageway from an opening in the patient's body to a desired intracorporeal location; c. forming a cavity at the desired intracorporeal location; d. inserting the catheter device through the opening and advancing the catheter device within the passageway until the cavity filling member on the distal shaft section is disposed within the cavity, wherein the cavity filling member is an inflatable balloon and the inflatable balloon is inflated after deployment within the cavity; e. folding or coiling the flexible proximal shaft section and placing the folded or coiled flexible proximal shaft section within the patient's body; f. closing the opening; g. deflating the inflated inflatable balloon; h. opening the closing or forming a new opening; i. removing the catheter device from the patient; and j. inserting a radiation balloon catheter having an inflatable balloon on a distal shaft section into the patient through the passageway and inflating the inflatable balloon on the radiation balloon catheter to expand the inflatable balloon within the cavity.
