摘要: 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.

摘要: Resorbable multifilament yarns and monofilament fibers including poly-4-hydroxybutyrate and copolymers thereof with high tenacity or high tensile strength have been developed. The yarns and fibers are produced by cold drawing the multifilament yarns and monofilament fibers before hot drawing the yarns and fibers under tension at temperatures above the melt temperature of the polymer or copolymer. These yarns and fibers have prolonged strength retention in vivo making them suitable for soft tissue repairs where high strength and strength retention is required. The multifilament yarns have tenacities higher than 8.1 grams per denier, and in vivo, retain at least 65% of their initial strength at 2 weeks. The monofilament fibers retain at least 50% of their initial strength at 4 weeks in vivo. The monofilament fibers have tensile strengths higher than 500 MPa. These yarns and fibers may be used to make various medical devices for various applications.

摘要: Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

摘要: Oriented resorbable implants made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof, have been developed that contain one or more antimicrobial agents to prevent colonization of the implants, and reduce or prevent the occurrence of infection following implantation in a patient. These oriented implants are particularly suitable for use in procedures where prolonged strength retention is necessary and there is a risk of infection. Coverings and receptacles made from poly-4-hydroxybutyrate and copolymers thereof, containing antimicrobial agents, have also been developed for use with implantable devices to prevent colonization of these devices, and to reduce or prevent the occurrence of infection following implantation of these devices in a patient. These coverings and receptacles may be used to hold, or partially or fully cover, devices such as pacemakers and neurostimulators. Preferably, the coverings and receptacles are made from meshes, non-wovens, films, fibers, and foams, and contain rifampin and minocycline.

摘要: Resorbable three-dimensional implants that can be temporarily deformed, implanted by minimally invasive means, and resume their original shape in vivo, have been developed. These implants are particularly suitable for use in minimally invasive procedures for tissue reinforcement, repair of hernias, and applications where it is desirable for the implant to contour in vivo to an anatomical shape, such as the inguinofemoral region. In the preferred embodiment, the implants are made from meshes of poly-4-hydroxybutyrate monofilament that have reinforced outlying borders that allow the meshes to form three-dimensional shapes that can be temporarily deformed. These implants can resume three-dimensional shapes after being temporarily deformed that contour to the host's tissue or an anatomical shape, for example, in the repair of a hernia, and particularly a hernia in the inguinofemoral region. The implants can contour to the host's tissue for example, of the inguinofemoral region, without the implants wrinkling, bunching or folding.

摘要: Expandable absorbable implants have been developed that are suitable for breast reconstruction following mastectomy. The implants can be implanted in the vicinity of a tissue expander, for example, by suturing to the detached edge of the pectoralis major muscle to function as a pectoralis extender, and used to form a sling for a tissue expander. The implants, which permit tissue-ingrowth and slowly degrade, can be expanded in the breast using a tissue expander in order to form a pocket for a permanent breast implant. After expansion, the tissue expander can be removed and replaced with a permanent breast implant. The expandable implants help reduce patient discomfort resulting from tissue expansion, and avoid the need to use allografts or xenografts to create the pocket for the tissue expander. The expandable absorbable implant preferably comprises poly-4-hydroxybutyrate or copolymer thereof.
