    • The disclosure is directed to radiation catheter devices, methods for controlled application of irradiation to tissue at a body site, such as a cavity formed after removal of tissue, e.g. cancer, using such radiation catheter devices, solutions for forming a more lubricious luminal surface and method for lining lumens of such devices to improve the frictional characteristics thereof. The catheter device includes a flexible elongated shaft which is formed of low durometer polymeric material, which can be readily folded or coiled for securing the shaft to or under the skin of the patient and a radiation lumen lined with high durometer polymeric material to improve the frictional characteristics. The elongated shaft has at least one inner lumen for receiving a radiation source which has a layer of high durometer polymeric material that provides lower surface friction to facilitate advancement of a radiation source therein.

    • 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.

    • The invention is directed to an intracorporeal marker, a delivery device and assembly for such marker and the method of delivering one or more of the markers to an intracorporeal location within a patient. The marker is a body formed at least in part of a bioabsorbable fibrous material such as a fibrous mat or fabric. The delivery devices preferably also include one or more bioabsorbable short term markers which are configured to expand within the body cavity due to contacting a body fluid. The fibrous marker has a radiographically detectable member which preferably hold a portion of the fibrous body in a compressed condition. Preferably, the fibrous marker has a fibrous felt core formed of bioabsorbable material with a fabric jacket formed of bioabsorbable material. Therapeutic, diagnostic and binding agents may be incorporated into the fibrous body of the marker.
