    摘要: A system for at least partially filling and marking a cavity at a site within a patient's body includes a marker delivery device having a chamber configured to contain a marking substance and having a mechanism configured to expel the marking substance. A quantity of the marking substance is contained within the chamber of the marker delivery device. The marking substance is configured to at least partially fill the cavity and form therein a porous bioabsorbable body. A delivery tube is coupled in fluid communication with the chamber of the marker delivery device. The delivery tube has a distal end with a discharge port through which the marking substance is expelled. A releasable remotely detectable distal tip is coupled to the distal end of the delivery tube and is configured to be released to remain within the porous bioabsorbable body within the cavity upon the formation thereof.

    摘要: A solution for forming a marker or filler mass for an intracorporeal site. The solution contains a polar, water soluble non-aqueous solvent such as dimethyl sulfoxide and a bioabsorbable, essentially water insoluble polymer such as polylactic acid, or copolymers of lactic acid and glycolic acid. The solution may be delivered to the biopsy site by a suitable syringe and delivery tube. The delivery tube is preferably provided with a releasable radiopaque element on the distal tip which can be released within the polymeric marker mass formed in the biopsy cavity.

    摘要: The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging. The biopsy site marker may be accurately fixed to the biopsy site so as to resist migration from the biopsy cavity when a placement instrument is withdrawn, and when the marked tissue is subsequently moved or manipulated.
