    摘要: The invention provides materials, devices and methods for marking biopsy sites for a limited time. The biopsy-marking materials are ultrasound-detectable bio-resorbable powders, with powder particles typically between about 20 microns and about 800 microns in maximum dimension, more preferably between about 300 microns and about 500 microns. The powders may be formed of polymeric materials containing cavities sized between about 10 microns and about 500 microns, and may also contain binding agents, anesthetic agents, hemostatic agents, and radiopaque markers. Devices for delivering the powders include tubes configured to contain the powders and to fit within a biopsy cannula, the powders being ejected by action of a syringe. Systems may include a tube containing powder, and a syringe containing sterile saline. The tube may be configured to fit within a biopsy cannula such as a Mammotome® or SenoCor 360™ cannula.

    摘要: An intracorporeal marker includes a fibrous unitary marker body having bioabsorbable fibers compressed into a compressed configuration, and bound in the compressed configuration by a polymer binding agent. The intracorporeal marker may be incorporated into an intracorporeal marker delivery device having a delivery cannula which has a distal tip, an inner lumen and a discharge opening in communication with the inner lumen. The compression and binding occur prior to insertion of the fibrous unitary marker body into the inner lumen of the delivery cannula. The fibrous unitary marker body is slidably disposed within and pushable through the inner lumen of the elongated delivery cannula proximal to the discharge opening.
