Patent number: 11877898Abstract: A biopsy site marker configured to expand upon deployment into a biopsy cavity, and visible under several different imaging modalities, comprises a superabsorbent hydrogel component and a radiopaque element. The hydrogel is in a compressed, dehydrated state prior to deployment to facilitate placement of the marker within the biopsy site, and thereafter expands upon deployment in the biopsy site.

Patent number: 11877857Abstract: Examples of the present disclosure describe systems and methods for the long-term, real-time active monitoring of a wireless implant. In aspects, a wireless biosensor may be implanted in a breast biopsy cavity. The biosensor may detect biochemical parameter data of the breast biopsy cavity and the human body. The biosensor may transmit the detected biochemical parameter data in real-time to a surveillance system wirelessly coupled to the biosensor. The surveillance system may then facilitate the evaluation of the biochemical parameter data. In examples, the evaluation may comprise detecting trends in a tumors microenvironment, monitoring the progress of a treatment, or adjusting a treatment to tailor a personalized treatment.Type: GrantFiled: September 10, 2018Date of Patent: January 23, 2024Assignee: Hologic, Inc.Inventor: Estefania Alvarez

Publication number: 20240016461Abstract: For a biopsy guided by contrast-enhanced x-ray imaging, a breast imaging system may image a patient's breast subsequent to injection of contrast agent to locate a site for biopsy and/or position a biopsy device relative to the site. Once a tissue specimen is removed from the site for diagnostic evaluation, a confirmation that the specimen was removed from an intended area of interest for biopsy is performed using the systems and methods described herein. For example, the breast imaging system and/or a separate specimen imaging system may capture high and low energy images of the specimen, subtract the low energy image from the high energy image to generate a subtracted image of the specimen, and determine, based on the subtracted image, that the contrast agent is present within the specimen to confirm the site from which the specimen was removed is the intended site for biopsy.Type: ApplicationFiled: August 31, 2021Publication date: January 18, 2024Applicant: HOLOGIC, INC.Inventors: David WOLFF, Stewart SCHIFFMAN
