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: 20230389690Abstract: Described herein are devices for cleansing the internal surface of various body cavities. The devices generally include a handle and one or more cleansing tips having different sets of cleansing surfaces. In addition to removing debris, and disrupting bacterial biofilms so as to make these bacteria more susceptible to various cleansing agents, the devices may be configured to deliver an antiseptic agent, an anti-inflammatory agent, or a fragrance to the body cavity surfaces, or deliver UV light to sanitize the surfaces. Methods for cleansing the surfaces of body cavities such as the nasal passages and vaginal cavity are also described herein. Systems including one or more cleansing devices and one or more cleansing formulations are further described.Type: ApplicationFiled: May 11, 2023Publication date: December 7, 2023Inventors: Gail S. LEBOVIC, Michael J. DREWS, Steven N. GROLLE, George D. HERMANN

Patent number: 11826029Abstract: A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable laterally within a plane of the base material to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return laterally towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch or integrally attached to a tubular graft or in various shapes.Type: GrantFiled: June 29, 2020Date of Patent: November 28, 2023Assignee: Solinas Medical Inc.Inventors: James Hong, Michael J. Drews

Patent number: 11752361Abstract: An implantable device has a body that is substantially rigid and has an imageable shape. The body is further bioabsorbable and may contain permanent metallic elements to aid in its imaging. When the device is implanted in a resected cavity in soft tissue, it can cause the cavity to conform substantially to a known imageable shape. The implantable device is further imageable due to its attenuation properties being different from those of soft tissue such that the boundaries of the tissue corresponding to the predetermined shape can be determined.Type: GrantFiled: January 30, 2019Date of Patent: September 12, 2023Assignee: HOLOGIC, INC.Inventors: James B. Stubbs, George D. Hermann, Gail S. Lebovic, Michael J. Drews

Patent number: 11756452Abstract: Described herein are anatomical models for medical training, surgical planning, or patient demonstration. The anatomical models include a replica of a target body part that may be altered, unfinished, or deformed so that an anatomical component may be attached thereto to complete the replica and provide visual training with respect to symmetry and other aspects of medical or surgical procedures. For example, the anatomical models may be altered, unfinished, or deformed to simulate a post-surgical deformity. Systems and methods including the anatomical models are also described herein.Type: GrantFiled: September 22, 2021Date of Patent: September 12, 2023Assignee: Silicon Valley Innovations, Inc.Inventors: Gail S.
