Patent number: 11944509Abstract: An implantable tissue marker device is provided to be placed in a soft tissue site through a surgical incision. The device can include a bioabsorbable body in the form of a spiral and defining a spheroid shape for the device, the spiral having a longitudinal axis, and turns of the spiral being spaced apart from each other in a direction along the longitudinal axis. A plurality of markers can be disposed on the body, the markers being visualizable by a radiographic imaging device. The turns of the spiral are sufficiently spaced apart to form gaps that allow soft tissue to infiltrate between the turns and to allow flexibility in the device along the longitudinal axis in the manner of a spring.Type: GrantFiled: September 27, 2022Date of Patent: April 2, 2024Assignee: HOLOGIC, INC.Inventors: George D. Hermann, David B. Willis, Michael J. Drews, Gail S. Lebovic, James B. Stubbs

Publication number: 20230157810Abstract: Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.Type: ApplicationFiled: November 21, 2022Publication date: May 25, 2023Applicant: HOLOGIC, INC.Inventors: Gail S. LEBOVIC, David B. WILLIS, George D. HERMANN, Jonathan M. OLSON

Publication number: 20220273394Abstract: Tissue localization devices and methods of localizing tissue using tissue localization devices are disclosed. The tissue localization device can comprise a handle comprising a delivery control, a delivery needle extending out from the handle, and a localization element within the delivery needle. The localization element can be deployed out of the delivery needle or retracted back into the delivery needle when the delivery control is translated in a first direction or a second direction, respectively. The localization element can be coupled to a flexible tracking wire.Type: ApplicationFiled: March 17, 2022Publication date: September 1, 2022Applicant: HOLOGIC, INC.Inventors: George D.
