Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.

A three-dimensional (3D) biocompatible, degradable soft tissue implant, comprising a bioprinted composite scaffold, the composite scaffold comprising a recombinant human collagen (rhCollagen) and a biocompatible synthetic polymer and features: a porous wall; an inner cavity at least partially enclosed within the porous wall; and at least one injection port that connects the inner cavity with an outer most surface of the scaffold, wherein the injection port has an opening sized to permit insertion of an injection device through the port, processes of preparing same and uses thereof in soft tissue reconstruction are provided. Injectable matrices for use in soft tissue reconstruction, either alone or in combination with the implant are also provided.

The present invention relates to breast-conserving surgery with volume replacement using dADM for breast cancer.

The surgical method according to the present invention is oncologically and cosmetically effective in terms of reducing postoperative fat necrosis, and may easily preserve the volume and shape of the preoperative breast mound. The effective shortening of the surgical time and a significant reduction in intraoperative bleeding may significantly reduce the incidence of postoperative complications such as postoperative intramammary fat necrosis and skin flap necrosis after the occurrence of subcutaneous fat necrosis.

A hybrid medical device that can aid in reconstructive or augmentative surgery of the breast is disclosed. The device can utilize a suitable biological collagen tissue matrix combined with a synthetic material, for example, that can impart a high initial strength to the repair site while permitting proper healing and revitalization of the implanted device.

A method for manufacturing an implant for implantation into a human body, includes preparing a mold having an inner space part so as to have an inner shape corresponding to a defective portion in a human body; injecting silicone foam into the space part of the mold; curing the silicone foam while applying pressure to same; and removing the mold.

Autologous prevascularized breast tissue constructs created via 3D printing and methods for 3D printing autologous prevascularized breast tissue constructs. The method comprises steps of: (i) providing a triculture consisting of adipose mesenchymal stem cells, fibroblasts, and endothelial progenitor cells, (ii) mixing the triculture cells with a bioink composed of biopolymers, (iii) printing three-dimensional structures of the breast tissue construct using the triculture-added bioink from step (ii), where the cells of the triculture are pretreated with growth media before printing so that the endothelial progenitor cells differentiate into endothelial cells and the adipose mesenchymal stem cells differentiate into adipocytes. After 3D printing, the development of vascular-like structures is induced.

This invention relates generally to a breast implant having an ePTFE layer, a Silicone layer of a breast implant core, and an interface between the ePTFE layer and the Silicone layer.

Embodiments herein relate to an implant for insertion into a patient. The implant comprises a plurality of unit cells arranged to form a three-dimensional lattice structure, the three-dimensional structure comprising a resting volume of the implant. The plurality of unit cells are arranged to form a porous network of the three-dimensional structure, and wherein the three-dimensional structure is a reversibly compressible three-dimensional structure, wherein a bulk porosity of the three-dimensional structure of the implant is at least 50%. Also disclosed is a method of tissue reconstruction or tissue augmentation. The method comprises implanting into the body of a subject an implant of the disclosure.

Tissue engineering devices and methods employing scaffolds made of absorbable material for use in the human body for tissue genesis and regenerative and cellular medicine including breast reconstruction and cosmetic and aesthetic procedures and supplementing organ function in vivo.

A method is disclosed for preparing a soft tissue site, and augmenting the soft tissue site, such as the breast(s), scar, depression, or other defect, of a subject through use of devices that exert a distractive force on the breast(s) and grafting of autologous fat tissue such as domes and sealing rims for surrounding each of the soft tissue site and a regulated pump. The method for preparing the soft tissue site, and enhancing fat graft results, entails application of the distracting force to the targeted soft tissue site at least intermittently for some period of time and preferably several weeks prior to the graft procedure. A rotated aspect of the invention includes following the preparation steps by transfer of fat from other areas of the subject to the subject's soft tissue site, and then reapplication of the distractive force to the soft tissue site that received the autologous fat graft. Alternatively, fat from genetically related sources may be used, and the fat may be further processed prior to injection. Substantial soft tissue augmentation, high rates of graft survival and negligible graft necrosis (data demonstrating 80% survival and only 20% necrosis is presented) or calcification result from the practice of these methods.
