Abstract
A method for maintaining access to a biopsy site within a patient, includes forming a passageway from an opening in an exterior site on the patient to a desired location for a biopsy specimen within the patient; removing a tissue specimen from the desired location thereby leaving a biopsy cavity; providing a temporary catheter having an elongate shaft, a flexible proximal shaft section, and a distal shaft section having a cavity filling member thereon; inserting the cavity filling member on the distal shaft section into the biopsy cavity; inflating the cavity filling member after inserting the cavity filling member within the biopsy cavity, but before closing the opening, using the flexible proximal shaft section; placing the flexible proximal shaft section at an intracorporeal location; and closing the opening so as to seal the passageway.
