Patent number: 8858628Abstract: A tissue expansion device implanted in a non-activated state over a region of desired tissue growth. Once implanted and positioned the device is activated creating a supporting structure that creates a convex shaped dome over the underlying tissue. The convex shaped dome formed by the tissue expansion device places a tensile stress against the underlying tissue that promotes tissue growth. Alone or with the introduction of tissue enhancing agents and/or adipose tissue, new tissue within the convex shaped void grows until a balance is achieved eliminating the induced stress. Periodically the tissue expansion devices is again activated and enlarged creating an even larger void. Again, the newly enlarged void places additional tensile stress on the underlying tissue thus repeating the cycle of new tissue growth. Once the desired amount of tissue growth has been achieved the device is deactivated and removed.Type: GrantFiled: December 14, 2007Date of Patent: October 14, 2014Assignee: Allergan, Inc.Inventors: Gino Rigotti, Guido Baroni

Patent number: 8821574Abstract: A valve assembly for an implant has an inner shell, a self-sealing material disposed within the inner shell, and an insertion pathway extending through the self-sealing material. At least one gap is formed in the self-sealing material that intersects with the insertion pathway to define a proximal pathway section and a distal pathway section. A filling tube is passed through the valve assembly for filling the outer shell of the implant with a fluid. After the implant is filled, the filling tube is removed. As the filling tube is removed, if the self-sealing material within the distal section of the pathway is unable to self-seal before the fluid reaches its proximal end, the fluid is diverted into the gap. The time that elapses before the gap is completely filled by the fluid provides sufficient time for the self-sealing material within the proximal section of the pathway to self-seal.Type: GrantFiled: December 5, 2012Date of Patent: September 2, 2014Assignee: Mentor Worldwide LLCInventor: Amir Davodian

Publication number: 20140156001Abstract: A valve assembly for an implant has an inner shell, a self-sealing material disposed within the inner shell, and an insertion pathway extending through the self-sealing material. At least one gap is formed in the self-sealing material that intersects with the insertion pathway to define a proximal pathway section and a distal pathway section. A filling tube is passed through the valve assembly for filling the outer shell of the implant with a fluid. After the implant is filled, the filling tube is removed. As the filling tube is removed, if the self-sealing material within the distal section of the pathway is unable to self-seal before the fluid reaches its proximal end, the fluid is diverted into the gap. The time that elapses before the gap is completely filled by the fluid provides sufficient time for the self-sealing material within the proximal section of the pathway to self-seal.Type: ApplicationFiled: December 5, 2012Publication date: June 5, 2014Applicant: Ethicon, Inc.Inventor: Amir Davodian

Publication number: 20140148901Abstract: The apparatus includes a funnel member, a coupling member and retractors. The funnel member is flexible and is frusto-conical in shape. The funnel member proximal end opening is larger than the distal end opening. The funnel member couples to a distal or coupling member that is located at the funnel member distal end portion. The distal or coupling member is rigid and has catches for removably coupling to the retractors. In use, the retractors anchor the apparatus to the patient while allowing the funnel member to be manipulated to force the prosthesis into a surgical cavity of a patient.Type: ApplicationFiled: January 29, 2014Publication date: May 29, 2014Inventors: Robert G. Anderson, Bryan Hunt

Publication number: 20140142696Abstract: An implant for marking an area within a living body includes a matrix material and a marking material. The implant is formable to fit the shape and size of a cavity in the human body. The implant is configured to support tissue surrounding the cavity and to allow in-growth of fibrous tissue into and replace at least a portion of the matrix material.Type: ApplicationFiled: January 28, 2014Publication date: May 22, 2014Applicant: SenoRx, Inc.Inventor: John D.

Patent number: 8728159Abstract: Disclosed is a mammary prosthetic implant with an expandable mammary prosthesis that expands to an enlarged state after implantation. A prosthetic device supports, and conforms to the shape of, the mammary prosthesis before, during, and after the mammary prosthesis is expanding within the implantation site. The prosthetic device has an absorbable main body formed of other than biological tissue, and is penetrable for the in-growth of dermal or subcutaneous tissue. The main body has an anterior end portion, an opposite posterior end portion, and a size relative to the mammary prosthesis upon implantation so that the anterior end portion engages an incised portion of a pectoralis major extending anteriorly of the mammary prosthesis while the opposite posterior end portion engages tissue inferiorly spaced from the incised portion of the pectoralis major and near the inframammary fold. Methods of preparing and using a prosthetic device as described herein also are disclosed.Type: GrantFiled: November 29, 2011Date of Patent: May 20, 2014Assignee: Northwestern UniversityInventor: John Y S Kim
