Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A marking system, comprising: a delivery tube; and an ultrasound-detectable biopsy marker carried by the delivery tube, the ultrasound-detectable biopsy marker formed of particles of material having internal bubble cavities, wherein a particle size of the particles is between about 200 microns and about 500 microns, and the bubble cavities have a size of at least 50 microns, wherein the bubble cavities have geometric centers and the bubble cavity size is…
