    摘要： 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.

    摘要： A marker delivery device includes an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen. At least one elongated fibrous marker body is slidably disposed within the inner lumen of the elongated delivery cannula. The at least one elongated fibrous marker body includes a plurality of bioabsorbable polymeric strands. The strands are compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula. A releasable plug is disposed within a distal portion of the inner lumen and distal to the at least one elongated fibrous marker body so as to at least partially occlude the discharge opening in the distal end section.
