The soft segment comprises (a) at least 2% by weight of the soft segment of at least one polyether macrodiol, and/or at least one polycarbonate macrodiol; and (b) at least 2% by weight of the soft segment of at least one polyisobutylene macrodiol and/or diamine.Type: GrantFiled: December 6, 2019Date of Patent: November 16, 2021Assignee: University of Massachusetts LowellInventors: Rudolf Faust, Umaprasana Ojha

Patent number: 11154393Abstract: Full contour absorbable implants for breast surgery redistribute breast volume between the breast's upper and lower poles in exact and desirable ratios. The implants preferably redistribute breast volume so that the upper pole breast volume is 20-40% of the total volume, and the lower pole breast volume is 60-80% of the total volume. The implants are also designed to provide specific curvatures to the poles of the breast, and to angulate the nipple areolar complex slightly skyward so that the patient's nipple is positioned at an angle above the nipple meridian reference line. The implants are designed to be transitory, with sufficient strength retention to allow transition from support of the breast by the implant to support by regenerated host tissue growing in and around the implants, without any significant loss of support during or subsequent to remodeling. The implants may optionally be used with permanent breast implants.Type: GrantFiled: January 30, 2019Date of Patent: October 26, 2021Assignee: Tepha, Inc.Inventors: Skander Limem, Said Rizk, Simon F.

Patent number: 11116620Abstract: Devices, systems, and methods for delivering prosthesis implants into surgically-created implant pockets in a subject and for preventing capsular contracture resulting from surgical insertion of prosthesis implants. The device may include a delivery member operable to wrap around the implant thereby forming a conforming cavity around the implant that conforms to the shape of the implant. The delivery member is also operable to propel the implant from the conforming cavity into the implant pocket in the subject upon the application of mechanical force to the delivery member. The device also includes a shielding member coupled with the delivery member. The shielding member is operable to shield the implant from at least a portion of the dissection tunnel connecting the incision to the implant pocket during delivery of the implant to the implant pocket.Type: GrantFiled: December 10, 2020Date of Patent: September 14, 2021Inventor: Stephen David Bresnick

Patent number: 11096771Abstract: A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.Type: GrantFiled: July 26, 2017Date of Patent: August 24, 2021Assignee: Leibniz-Institut für Neue Materiallen gemeinnützige GmbHInventors: Eduard Arzt, Sarah Fischer, Klaus Kruttwig, René Hensel, Bernhard Schick, Gentiana Wenzel

Patent number: 11090146Abstract: A size adjustable cover used for soft tissue reinforcement which is adapted to envelop an implantable device, such as a breast implant, in a surgical application. The cover is formed using a circular two-dimensional implantable matrix material having an inner circle and a plurality of fringes which radiate circumferentially from the inner circle. The implantable device is positioned upon the inner circle, and the plurality of fringes are folded inwardly to form an overlapping implant pocket which envelops the implantable device. Each fringe further has a punched opening, allowing a loop of suture thread to link each fringe together. Certain fringes are excluded from the loop to create stabilization tabs which radiate from the inner circle and are attached to a site of host implantation to stabilize the cover and the implantable device within.Type: GrantFiled: July 18, 2019Date of Patent: August 17, 2021Inventor: Anke Young
