    摘要: A keratin hydrogel-filled implantable prosthetic device. One device is a breast implant for augmenting or reconstructing a human breast including an envelope containing a keratin hydrogel. Another device is an implant for the intervertebral disc space. One keratin hydrogel is formed from a solid precursor which forms a keratin hydrogel upon addition of water. One source of keratin is human hair. In one method, an envelope suitable for implantation and a solid keratin hydrogel precursor are provided. The solid can be in fibrous or powder form. The solid precursor can be inserted into the envelope interior. A small incision near the breast can be made and the envelope inserted into the incision. After insertion, water can be injected into the envelope interior, preferably through the incision and through a self-sealing port in the envelope. In one method, the implant is provided as a kit, with the envelope and keratin hydrogel provided. The hydrogel can be injected into the envelope either before or after insertion into the breast area. One kit has a powdered, keratin hydrogel precursor disposed within the envelope interior, awaiting the addition of water, preferably after insertion of the implant into the body. In another method, the implant can include an envelope with a hydrogel or hydrogel precursor already placed in the envelope.

    摘要: Systems and method in accordance with embodiments of the present invention can includes an implant having a spacer with an expandable portion. An insert can be positioned within a groove of the spacer to distract the expandable portion away from the main portion of the spacer. The expandable portion can optionally include a grip that can at least partially deform to conform to a contour of a spinous process to provide a frictional grip to prevent the implant from shifting position. Implants in accordance with the present invention can also include a binder that can be arranged around the adjacent spinous processes to limit flexion movement.
