摘要:
An implant (10) for repairing a segmental defect in a subject's bone at a segmental defect site, the implant comprising a scaffold (20) for implantation at the segmental defect site and the implant optionally comprising: a plate for internal fixation, the plate being attachable to or integral with the scaffold, and the plate having means for securing it to bone outside of the segmental defect site; a hollow cavity within the scaffold; a plurality of longitudinal channels within the scaffold; and or a membrane received around the scaffold.
摘要:
An enclosure provides a prophylactic barrier that may be permeable to gases, hormones, proteins, and peritoneal fluid, but restrains tumor cells within the enclosure so as to inhibit ovarian cancer invasion of adjacent tissue, and increase the speed of diagnosis of ovarian dysplasia, including cancer. The enclosure includes one or more of fiducial markers, heat sensors, and blood flow reflectors, which may be imaged non-invasively in order to detect conditions or pathology affecting the ovary. The enclosure may also include an access port that permits sampling of the enclosure's contents to further aid in detecting or treating conditions or pathology affecting the ovary.
摘要:
An implantable, pliable silk device (e.g., in a form of a knitted mesh) for use in human soft tissue support and/or repair that provides stretch or pliable properties, e.g., multi-directional elongation properties. Such a device permits physicians or users to alter or manipulate the device dimension and/or shape at the time of device implantation, thereby permitting the device to conform to the contour of a target area or tissue more easily and providing more precise positioning of the device over the target area or tissue. In some embodiments, the implantable pliable silk device comprises a knit pattern feature that substantially prevents unraveling and preserves the stability of the mesh when cut. For example, the pliable silk device is a knitted mesh comprising at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes.

Compliance control stitch patterns sewn or embroidered into biotextile or medical textile substrates impart reinforcing strength, and stretch resistance and control into such substrates. Compliance control stitch patterns may be customizable to particular patients, substrate implantation sites, particular degenerative or diseased conditions, or desired time frames. Substrates having compliance control stitch patterns sewn or embroidered into them may be used in tissue repair or tissue reconstruction applications.
摘要:
One aspect of the present disclosure relates to a tissue repair implant comprising a first layer of extracellular matrix and a second support layer of biocompatible material securely attached to the first layer at one or more fixation points. At least one of the fixation points comprises a first projection that is associated with the first layer and securely attached, via a fixation mechanism, to the second support layer.

摘要:
Methods of tissue passivation are described herein for use in preserving normal tissue architecture, reducing post-surgical inflammation, and reducing or preventing the development of pathogenic collagen bundles and adhesions following surgical procedures (e.g., grafting, implanting).
摘要:
This invention relates generally to a dehydration device and methods for drying biological materials to produce dried biological materials having enhanced structural properties. More specifically, the invention relates to a dehydration device and related methods for drying biological tissue to produce enhanced tissue grafts.
摘要:
Described herein are tissue grafts derived from the placenta that possess good adhesion to biological tissues and are useful in would healing applications. In one aspect, the tissue graft includes (1) two or more layers of amnion, wherein at least one layer of amnion is cross-linked, (2) two or more layers of chorion, wherein at least one layer of chorion is cross-linked, or (3) one or more layers of amnion and chorion, wherein at least one layer of amnion and/or chorion is cross-linked. In another aspect, the grafts are composed of amnion and chorion cross-linked with one another. In a further aspect, the grafts have one or more layers sandwiched between the amnion and chorion membranes. The amnion and/or the chorion are treated with a cross-linking agent prior to the formation of the graft. The presence of the cross-linking agent present on the graft also enhances adhesion to the biological tissue of interest. Also described herein are methods for making and using the tissue grafts.
