MEDICAL DEVICES CONTAINING COMPOSITIONS OF POLY(BUTYLENE SUCCINATE) AND COPOLYMERS THEREOF
Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The 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 molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

Apparatus, system and methods for improved breast surgery with myointegration
The present disclosure is directed to Myointegration, the improvement of breast implant apparatus, system and methods for a design that extends the breast implant centrifugally, or in which a separate device is utilized in combination with a breast implant, that has one or more straps originating from the breast implant extension or from the separate device. The one or more straps are looped through the pectoralis major muscle then back into the implant extension or the separate device repeatedly. The straps are eventually attached in some manner to themselves, to the implant extension, or to the separate device. Since the pectoralis major muscle contains neuromuscular spindles that sense length, velocity and acceleration, when the user changes position from supine to vertical, the gravitational force generated by the mass of the breast implant pulls on the strap or straps, which pulls the muscle and stimulates the neuromuscular spindles, thereby generating lift of the implanted breast insert.
FIXED-SHAPE TISSUE MATRIX AND RELATED METHODS
The present disclosure provides tissue products produced from a combination of three-dimensional biologic scaffolds and acellular tissue matrices. The tissue products may include features for suture or fixation reinforcement. The tissue products may harness various properties of different acellular tissue matrices and different three-dimensional biologic scaffolds to provide improved composite structures with desired mechanical and/or biologic properties.
PRE-SHAPED ALLOGRAFT IMPLANT FOR RECONSTRUCTIVE SURGICAL USE AND METHODS OF MANUFACTURE AND USE
An acellular dermal matrix (ADM) graft product includes an ADM graft derived from full-thickness skin, with a pre-formed shape having a mesh pattern formed therein. The ADM graft is disposed in a sterilization package and irradiated to provide a two year shelf-life for the ADM graft product, which is used in the time-saving, efficient, and effective surgical reconstruction of soft tissue defects. One manufacturing method involves providing a portion of full-thickness donor-derived skin, removing an epidermis and a fat layer form the portion of the skin, decellularizing the portion of the skin to form a portion of ADM graft material, pre-shaping and meshing the ADM graft material, verifying a thickness of the ADM graft material, and packaging the pre-shaped, meshed ADM graft material in a sterilizable package and irradiating for a two-year shelf-life to form the ADM graft product. Other embodiments are also disclosed.
HERNIA REPAIR, BREAST RECONSTRUCTION AND SLING DEVICES CONTAINING POLY(BUTYLENE SUCCINATE) AND COPOLYMERS THEREOF
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.
Medical/Surgical Implant
The present invention relates to the field of implants. In particular, the present invention relates to an implant for tissue reconstruction which comprises a scaffold structure that includes a void system for the generation of prevascularized connective tissue with void spaces for cell and/or tissue transplantation. Moreover, the present invention relates to a method of manufacturing such an implant, to the internal architecture of such an implant, to a removal tool for mechanical removal of space-occupying structures from such an implant, to a kit comprising such an implant and such a removal tool, to a removal device for the removal of superparamagnetic or ferromagnetic space-occupying structures from such an implant, as well as to a guiding device for providing feedback to a surgeon during the procedure of introducing transplantation cells into the void spaces generated upon removal of space-occupying structures from such an implant.
TISSUE TRANSFER SYSTEMS
Devices and methods for tissue transfer are described where a cannula may be inserted into the breast of a subject at one of several points of entry. Insertion of the cannula into the breast may be accomplished by using a guidance system to distinguish between tissue types. Once desirably positioned, the cannula may be withdrawn from the breast while automatically (or manually) injecting the fat in multiple deposits of adipose tissue or fat such that the deposited fat remains within the tract formed by the withdrawn cannula. Multiple tracts of the deposited fat may be injected within the breast until the breast has been desirably remodeled and/or augmented.
SOFT TISSUE REPAIR GRAFTS AND PROCESSES FOR PREPARING AND USING SAME
Soft tissue repair grafts are provided for supporting, covering, and/or retaining an implant positioned in the body of a subject. The grafts are particularly suitable for use for pre-pectoral breast reconstruction with a breast implant or tissue expander. The grafts include positional notches for more accurate positioning in a subject. The grafts also include at least one cuff element which is folded to form a reinforced folded edge for suturing the graft more securely to adjacent tissues than previously known grafts. The grafts also include a plurality of arcuate slots which form a plurality of circular patterns arranged concentrically about a focal point, thereby enabling the grafts to expand without tearing and to conform more closely to the implant and/or adjacent body tissues such as the breast pocket, than previously known grafts. Acellular dermal matrices are particularly suitable for making the soft tissue repair grafts.
POLAND SYNDROME AND METHODS OF TREATMENT
This invention is directed to grafts and compositions and methods of using the same to treat Poland Syndrome.
